Question

If the sequence of bases in sense strand of DNA is - GTTCATCG -, then the sequence of bases in its RNA transcript would be
(A) 5’ - GTTCATCG - 3’
(B) 5’ - GTTCAUCG -3’
(C) 5’ - CAAGTAGC -3’
(D) 5’ - CAAGUAGC -3’

Answer 1

DNA stands for the deoxyribose nucleic acid which is the double stranded and the RNA stands for ribonucleic acid but it is the single stranded protein. The DNA carries the genetic information from one generation to the other.

Complete answer:
The transcription is defined as the process in which the given genetic code of the double stranded DNA is copied to the messenger RNA. In the process the enzyme transcriptase is involved in the conversion. Where the reverse transcription is to convert the gene from the RNA to the DNA by the enzyme using reverse transcriptase.
According to the complementary base pair rule, A sets with T and G sets with C. Along these lines, if DNA sense strands have a base of GTTCATCG so the grouping of bases in RNA transcriptase would be CAAGUAGC as it is utilized to peruse the normal protein code. This is obtained by changing the letters G and T with the C and A. And the other letters remain the same.

Hence the correct answer is option(D)

Note: Transcription takes place in the nucleus of the cell. Transcription takes place in the three stages as the initiation, elongation and the termination. In this, the DNA template is used to make the RNA by using the enzyme transcriptase.
