The following DNA strand is used as a template for transcription:

3’ CGTAAGCGGCT 5’

Which of the following RNA strands will be produced:

A. 5’UCGGCGAAUGC 3’
B. 5’ GCAUUCGCCGA 3’
C. 5’ GCATTCGCCGA 3’
D 5’ CGUAAGCGGCU 3’

Respuesta :

The answer is B
C pairs with G, T pairs with A but in RNA T is replaced with U so A pairs with U

DNA replicates and produces two strands that are leading and a lagging strand. The formation of RNA from the antisense strand of DNA is called transcription.

The following RNA strand will be produced:

Option: B. 5’ GCAUUCGCCGA 3’

This can be explained as:

  • The nucleotide bases present in ribonucleic acids are adenine, guanine, cytosine and uracil.

  • RNA does not have thymine rather it contains uracil as a pyrimidine base.

  • When the complementary base will form the hydrogen bonds with the template sequences then adenine will bond with uracil, guanine with cytosine and vice versa.

Therefore, the RNA sequence formed from the DNA template will be

5’ GCAUUCGCCGA 3’
