Play media comment.Which of the following best completes the RNA sequence being created?
1 answer:
TACGAGAAT, ATGCTCTTA (DNA sequence)
UACGAGAAU, AUGCUCUUA (RNA sequence)
Explanation:
In RNA Uracil is replaced by Thymine.
SO,
5'TACGAGAAT3'
5'AUGCUCUUA3'
5'ATGCTCTTA3'
5'UACGAGUUA3'
Both RNA and DNA is synthesized from 5'to 3' direction. Uracil requires less energy than thymine to bond with Adenine in RNA hence preferred.
Cytosine easily gets deaminated to produce uracil so thymine is the preferred base in DNA.
