The alleles for eye color in fruit flies involves one allele that might contain the sequence CCAT. Assume that this allele produces red eyes in a fruit fly, because the allele produces a protein that makes red pigment. Assume that another allele of this gene has a slightly different sequence in the middle: CAAT, instead of CCAT.Which of the statements below is true about the alleles for eye color in fruit flies?

Which of the statements below is true about the alleles for eye color in fruit flies?

A)
The alleles for eye color produce the same phenotype.


B)
The small change in the DNA sequence causes the allele to produce a different protein, resulting in the production of white eyes instead of red eyes in the fruit fly.


C)
Changes in the sequence of DNA bases in a gene do not contribute to genetic variation in the fruit fly population

Answers

Answer 1
Answer:

Answer:

The correct answer would be B)  The small change in the DNA sequence causes the allele to produce a different protein, resulting in the production of white eyes instead of red eyes in the fruit fly.

The amino acid sequence of any protein is determined by the codon sequence of the mRNA which is in turn determined by the nucleotide sequence of the DNA.

Thus, if the nucleotide sequence of the DNA is changed, it will result in the change of amino acid sequence of the protein.

It may result in the change of the structure as well as the function of the protein.

Thus, if the sequence in the gene is changed slightly, it would not result in the production of protein required for a red color trait.

Hence, the eye color of the fruit fly would change to white.
Answer 2
Answer: I'm quite sure answer B is correct :)

In what way does prokaryotic fission resemble eukaryotic mitosis?

Answers

The ways prokaryotic fission resemble eukaryotic mitosis are:


a. movement of chromosomes 

b. genetically identical daughter cells 

c. intracellular mechanisms 


Chromosomes segregate, produce identical cells and it happens internally (to the cell) in both processes.

Which of these statements best compares gravitational and electromagnetic forces in the solar system? Electromagnetic forces are only repulsive but gravitational forces are both attractive and repulsive.
Electromagnetic forces are only attractive but gravitational forces are both attractive and repulsive.
Gravitational forces are only repulsive but electromagnetic forces are both attractive and repulsive.
Gravitational forces are only attractive but electromagnetic forces are both attractive and repulsive.

Answers

Gravitational forces are only attractive but electromagnetic forces are both attractive and repulsive.Because magnetic force has negative and positive charges, it can be both attractive and repulsive. Gravity affects objects at a distance, but the attraction weakens as the objects get farther apart.

Which change to one of the kits would make it useful for modeling proteins? a.Set 1, add a box for phosphorous (P) atoms. b.Set 2, add a box for sulfur (S) atoms c.Set 3, replace the box of phosphorous (P) atoms with a box of sulfur (S) atoms d.Set 4, replace the box of oxygen (O) atoms with a box of nitrogen atoms (N)

Answers

Answer:

The correct answer is - option C.

Explanation:

Proteins are made up of long chains of polypeptide chains made up of amino acids contain the basic elements of organic matter carbon, oxygen, and hydrogen with the addition of nitrogen.

In the given option set 1, and set 2 lacks the nitrogen elements whereas in set 4 the oxygen is not available, and set 3 have all the elements required for the protein.

Thus, the correct answer is - option C.

The kits would make it useful for the modellingproteins if set 3, replace the box of phosphorous (P) atoms with a box of sulfur (S) atoms . The correct option is c.

Proteinmodels can be quite useful in functional genomics because they provide structural insights that are frequently required to understand protein activity.

There are three main approaches to simulating a protein structure:  Threading/fold recognition; Abinitio modeling and homology modelling

Proteins are lengthy polypeptide chains made up of amino acids that contain the basic constituents of organic matter carbon, oxygen, and hydrogen with the addition of nitrogen.

Sets 1 and 2 are deficient in nitrogen elements, whereas Set 4 is deficient in oxygen, and Set 3 contains all of the elements required for the protein.

Thus, The correct option is c.

If a heterozygous plant seed color (Rr) is crossed with a homozygous recessive plant (rr), what is the probability of each seed color being produced?

Answers

If you draw the chart that crosses which genes each offspring would receive, the answer would be Rr, rr, rr and rr. With that you would say there is a 1 in 4 chance of getting Rr and 3 in 4 chances of getting rr.

Answer:

Explanation:If a heterozygous plant for seed color (Rr) is crossed with a homozygous recessive plant (rr), what is the probability of each seed color being produced? ... The probability will be ½ for each seed color.

Feather color in budgies is determined by two different genes Y and B. YYBB, YyBB, or YYBb is green; yyBB or yyBb is blue; YYbb or Yybb is yellow; and yybb is white. Two blue budgies were crossed. Over the years, they produced 22 offspring, 5 of which were white. What are the most likely genotypes for the two blue budgies?

Answers

Answer:

The most likely genotypes for the two blue budgies would be yyBb

Explanation:

There are three options to cross two blue parakeets:

yyBB x yyBB

yyBB x yyBb

yyBb x yyBb

of the first option, the F1 genotypes will be 100% yyBB  (blue)

In the second option, the F1 budgies will be yyBB or yyBb (blue in both cases). In contrast, in the third option, the F1 genotypes will be yyBB, yyBb (blue in both cases) and yybb (white).
