If I have 14 guanine and 37 thymine, how many adenine will I have?
Answers
If I have 14 guanine and 37 thymine, then 37 adenine bases will be present in the individual.
What is base pairing?Base pairing is the process by which nitrogenous bases in DNA molecules bind to each other through hydrogen bonds to form the characteristic double-stranded structure of DNA.
Adenine (A) is always associated with thymine (T), and cytosine (C) is always associated with guanine (G).
As a result, knowing the number of guanine and thymine bases in a DNA sequence allows us to calculate the number of adenine and cytosine bases.
We know there are 37 adenine bases because adenine always pairs with thymine and you have 14 guanine bases and 37 thymine bases.
This is because the number of A bases in a double-stranded DNA molecule will always equal the number of T bases, and the number of G bases will always equal the number of C bases.
Thus, there will be 37 adenines.

The graphs here show the distribution of beak depths for the ground
finches on Daphne Major, an island in the Galapagos. The bird beaks were
measured over a multi-year study, including a time period before and after
a drought. The drought reduced the supply of seeds and left most of the
seeds as thick-walled nuts that survived the drought. Analyze the data and
select the claim about natural selection and genetic diversity that is
supported by the data.
Natural selection tends to reduce genetic variation, as there was a smaller distribution
of beak depths, but it tends to select for the most fit phenotypes, as there was an
increase in average beak depth after the drought.
Natural selection tends to increase genetic variation, as there were more ground

Explanation:
Kidney is the main organ which is responsible for helping to keep the water concentration equal on each side of the cell membrane.
What is Kidney?The kidneys are the main organs in the body which remove waste products and extra water from the blood in the form of urine and also help to keep the chemicals such as sodium, potassium, and calcium balanced in the body. The kidneys also secrete hormones which help control blood pressure and stimulate bone marrow to make red blood cells.
Kidneys maintain water concentration in the body. Kidneys maintain homeostasis through osmosis. Osmosis is the phenomenon of movement of water or fluid particles from a region of higher concentration to a region of lower concentration through a semi-permeable membrane.

What are some ethical and philosophical questions that surround the issue of
genetic counseling? Might it sometimes be unwise to know ahead of time about
possible genetically linked disorders that might afflict your child or yourself?
Answers
Answer:
Genetic counseling raises concerns associated with confidentiality and privacy of the information. I consider that genetic information always is beneficial for the individual because this information can be used to determine the genetic predisposition of developing a particular inherited disease (and therefore prevent it).
Explanation:
Genetic counseling has historically been associated with concerns with confidentiality and privacy of genetic information. Genetic information about an individual such as carrier status (i.e., the presence of recessive deleterious alleles in the genome of the individual), his/her chance of developing a certain disease (e.g., cancer), or transmit this disease to his/her offspring is always stigmatizing, and therefore it must be kept confidential. In consequence, genetic information must be carefully handled by professionals because any filtration of this information may be harmful to the individual (for example, unscrupulous companies might use this information to select personal regarding the genetic predisposition to suffer inherited diseases). However, genetic information is very useful in order to determine the genetic predisposition of developing a particular inherited disease and thus take the necessary actions to prevent it (e.g., avoid high salt foods if there is a genetic predisposition of developing cardiovascular diseases).

What is the role of gene expression
Answers
Answer:
Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a particular cell determine what that cell can do.
Explanation:
In mouse, genes X, Y and Z are on chromosome 2. The map of genes X, Y and Z is:
X--------20mu--------Y---------------30mu---------Z.
You cross an individual with genotype XXYYZZ to an individual with genotype xxyyzz, and F1 progeny are collected. Assume interference between regions (X-Y and Y-Z) is 40%. You then perform a cross between an F1 individual and an individual with genotype xYz/xyz. Among 1000 progeny, how many of them will be of the genotype xxyyzz?
Answers
Answer:
36 individuals xxyyzz
Explanation:
Available data:
X-Y = 20MUY-Z = 30MUCross: XXYYZZ x xyyzzF1= XxYyZzI = 40%2nd Cross: XxYyZz x xxYyzzF2 = 1000 individualsWe need to know how many individuals from the F2 are going to be xxyyzz
xxyyzz genotype is the result of a double recombinant event.
First, we need to analyze the given information:
→ Distances between genes
The genetic distance result from multiplying the recombination frequency of each region by 100 and expressing it in map units (MU). So, if we have the genetic distance we can divide it by 100 and get the recombination frequency:
Let us say that region I is the distance between X and Y. And region II is the distance between Y and Z.
GD = genetic distance
RF = Recombination frequency
GD (X-Y) = RF x 10020MU = RF x 100
20MU/100 = RF
0.2 = RF (Region I)
GD (Y-Z) = RF x 10030MU = RF x 100
30MU/100 = RF
0.3 = RF (Region II)
Now we have the recombination frequency of Region I and Region II.
→ Interference
Knowing the interference value will let us know the value of the coefficient of coincidence, which will also lead us to the number of individuals xxyyzz.
I = 40%
I = 1 - CC ⇒ CC = coefficient of coincidence
Clearing this equation gives us the value of CC
CC = 1 - I
CC = 1 - 40% = 1 - 0.4
CC = 0.6
To calculate the coefficient of coincidence, CC, we can also use the next formula:
CC = observed double recombinant frequency/expected double recombinant frequency
Now, we are interested in knowing the value of the observed double recombinant frequency.
Note:
observed double recombinant frequency = total number of observed double recombinant individuals/total number of individuals expected double recombinant frequency = recombination frequency in region I x recombination frequency in region II.So, to get the value of the observed double recombinant frequency, first, we need to get the value of the expected double recombinant frequency. And we can do it because we already have the recombination frequencies in both regions.
expected double recombinant frequency = recombination frequency in region I x recombination frequency in region II
- Recombination Frequency - RI = 0.2
- Recombination Frequency - RII = 0.3
expected double recombinant frequency = 0.2 x 0.3
expected double recombinant frequency = 0.06 = EDRF
Now that we know the value of the CC and the expected DRF, we can get the observed double recombinant frequency.
CC = observed double recombinant frequency/expected double recombinant frequency
- CC = 0.6
- EDRF = 0.06
CC x expected double recombinant frequency = observed double recombinant frequency
0.6 x 0.06 = observed double recombinant frequency
0.036 = observed double recombinant frequency = ODRF
Finally, as this is a frequency, we need to multiply it by the total number of individuals in the F2 to get the number of observed double recombinant individuals.
- ODRF = 0.036
- N = 1000
Double recombinant individuals = 0.036 x 1000 = 36 individuals xxyyzz.

Answers
Answer:
Cytotoxic T cell - kills infected human cells after recognizing antigens displayed on MHC class 1 B.
Helper T cell - does not directly kill microbes; after recognition of a specific antigen displayed on MHC Class 2, it secretes molecules that help other cells to do so.
B cell - phagocytoses microbes after recognizing specific antigens; secretes antibodies
Natural Killer Cell - kills virus-infected human cells by releasing perforin and granzymes.
Macrophage - Phagocytoses microbes after recognizing PAMPs; acts as an Antigen Presenting Cell to activate another type of immune cell
Mast Cell - Does not directly kill microbes; secretes histamine to initiate an inflammatory response.
Explanation:
T cell are immune-response cells that originate in the bone marrow but migrate and develop in the thymus gland. They are of two classes; Cytotoxic T cells and Helper T cells.
Cytotoxic T cell - kills infected human cells after recognizing antigens displayed on MHC (Major histocompatibility complex) class 1 B.
Helper T cell - does not directly kill microbes; after recognition of a specific antigen displayed on MHC Class 2, it secretes molecules that help other cells to do so.
B cells are formed and develop in the bone marrow. They make antibodies against antigens, and phagocytoses microbes after recognizing specific antigen.
Natural Killer Cells are cytotoxic lymphocytes of the innate immune system. They kill virus-infected human cells by releasing perforin and granzymes.
Macrophages are a type of white blood cells that detects and phagocytoses microbes after recognizing PAMPs (Pathogen-associated molecular pattern) They also act as Antigen Presenting Cell (APCs) to activate another type of immune cell
Mast Cells are cells found in the connctive and they function as part of the immune system of the body. They do not directly kill microbes. They secrete histamine to initiate an inflammatory response.
