Question

If the following oligonucleotide of double-stranded DNA was transcribed, what would be the sequence of the RNA?

5'TGCTAGCTA3'
3'ACGATCGAT5'
A) 5'UGCUAGCUA3'
B) 5'ACGAUCGAU3'
C) 3'ACGATCGAT5'
D) 3'ACGAUCGAU5'

Answer 1

The sequence of the RNA transcribed from the given DNA sequence 5'TGCTAGCTA3' 3'ACGATCGAT5' is 5'UGCUAGCUA3'.

Step-by-step explanation:

The given oligonucleotide sequence of double-stranded DNA is 5'TGCTAGCTA3' 3'ACGATCGAT5'. To transcribe this DNA sequence into RNA, we need to replace each nucleotide with its complementary base.

In RNA, adenine pairs with uracil, guanine pairs with cytosine, cytosine pairs with guanine, and thymine is replaced by uracil. Therefore, the sequence of the RNA transcribed from this DNA would be 5'UGCUAGCUA3'.
