Question

Write the sequence of the mRNA molecule synthesized from a DNA template strand having the sequence 5’-ATCGTACCGTTA-3’. (b) What amino acid sequence is encoded by the following base sequence of an mRNA molecule?

Answer 1

Answer:

The mRNA molecule will be synthesized running in the 5' to 3' direction.

Explanation:

From the DNA sequence:

5'-ATCGTACCGTTA-3'

3'-TAGCATGGCAAT-5'

mRNA sequence is

5'-AUCGUACCGUUA-3'

Amino acid sequence will thus be:

Ileu-val-pro-leu.

Answer 2

Answer:

Explanation:

5’-ATCGTACCGTTA-3' }

3'-TACGATGGCAAT-5'}Dna template

mRNA -5'- AUCGUACCGUUA-3'

Ile. Val. Pro. stop

The amino acids include,

AUC- Isoleucine

GUA- -Valine

CCG-prolein

mRNA serves as an intermediary to convey the information in the DNA to the ribosome where translation into amino acid occur.
