question 73
the first codon in every mrna is
a aug.
b uac.
c aaa.
d methionine
e different for each mrna.

Explanation:

• For Question 72: In genetics, a functioning allele (often a dominant allele) can prevent the manifestation of a disease caused by a recessive allele. For example, in autosomal - recessive disorders, if an individual has one functioning (dominant) allele and one defective (recessive) allele, the functioning allele can prevent the disease phenotype.
• For Question 73: The start codon in mRNA is AUG. It codes for methionine in eukaryotes and N - formylmethionine in prokaryotes and serves as the initiation signal for translation.

Answer:

Question 72: A. can prevent a disease.
Question 73: A. AUG.
