Which one of the codons below would stop the translation of mRNA by ribosomal subunits?

Biology
1 answer:
Ostrovityanka [42]2 years ago
5 0

Answer:

The correct option is D) UAG, UAA, UGA

Explanation:

The amino acid sequencing code or mRNA code contains specific codes which start and stop the process of translation at the right time. If the stop codon were not present then the ribosomal machinery would have made faulty proteins. If the stop codons are not at the right place, then it results in the production of faulty proteins. The stop codons which terminate the process of translation are UAG, UAA and UGA.

Arada [10]

Answer:

a. autotriploid of species A: 63 chromosomes

b. autotetraploid of species B: 96 chromosomes

c. allotriploid from species A and B: 1) 66 chromosomes and 2) 69 chromosomes

Explanation:

<u>For a.</u>

this species will have 3 haploid sets of chromosomes ('tri' means 3)

one haploid set = 21

21 × 3 = 63 chromosomes

<u>For b.</u>

this species will have 4 haploid sets of chromosomes ('tetra' means 4)

one haploid set = 24

24 × 4 = 96 chromosomes

<u>For c.</u>

there are two ways to do this:

1) two sets of chromosomes from species A and one from species B

42 + 24 = 66 chromosomes

2) one set of chromosomes from species A and two from species B

21 + 48 = 69 chromosomes

Hope that answers the question, have a great day!
