julia-pushkina [17]

Answer:

Please, see the answer below.

Explanation:

The statement is inaccurate because a growing baby is not just a ball of multiplying cells that eventually grows large enough to form a baby.

<u>After fertilization and the formation of a single-cell zygote, the zygote continues to divide to form a ball of cells. However, at some points, the cells start to differentiate to give rise to various organs that make up the baby.</u>

<em>Without differentiation, there is not way the dividing cells will give rise to baby. Hence, a growing baby should be rather viewed as a ball of multiplying cells that eventually differentiates to form a baby.</em>

Which of the following mRNA sequences could code for the polypeptide met-arg-ser-leu-glu?
vampirchik [111]

Answer:

5'-AUGCGUAGCUUGGAGUGA-3'  

Explanation:

(a) Break the string into triplets.

5'-AUG-CGU-AGC-UUG-GAG-UGA-3'

The string contains six codons.

The initiation codon is AUG (Met)

That eliminates Options 1 and 4.

(b) Identify the stop codon

There are six codons, so the sixth is the stop codon, which must be UAA, UGA, or UAG .

That eliminates Option 2, which ends with UGG.

The correct answer must be Option 3.

(c) Check

Translate the codon string.

5'-AUG-CGU-AGC-UUG-GAG-UGA-3

    met   arg    ser    leu    glu    stop

That's the correct sequence.
