Question

question 39
a functioning allele on one chromosome.
a can prevent a disease.
b can cause a protein deficiency disease.
c can never be inherited by the offspring.
d can never make up for a defective allele.
e is usually inherited from the mother.
question 40
how many different amino acids are responsible for making up the thousands of different proteins found in a eukaryotic cell?
a 3
b 4
c 15
d 20
e thousands

Explanation:

• For Question 39: A functioning allele can produce the necessary protein product, which may prevent a disease - related phenotype from manifesting. It doesn't cause protein - deficiency diseases, can be inherited, can sometimes compensate for a defective allele, and there's no general rule that it's usually inherited from the mother.
• For Question 40: There are 20 different amino acids that are the building blocks for making up the various proteins in a eukaryotic cell.

Answer:

Question 39: A. can prevent a disease.
Question 40: D. 20
