Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What strand of mRNA would be produced from the strand of DNA shown below?GCT AAG
A
GCA UUG
B
CGA UUC
C
CGA TTC
D
GCT AAG
Explanation: 

Detailed explanation-1: -I believe the strand of mRNA that would be produced will be CGA UUC. mRNA is formed from the process of transcription which takes place in the nucleus where DNA molecule acts as primer, catalyzed by the enzyme RNA polymerase.

Detailed explanation-2: -Explanation: The Adenine joins with thymine while Guanine with Cytocine. So, GCATTA produce the strand of mRNA of CGTAAT sequence.

Detailed explanation-3: -Template strand is the DNA strand off which the mRNA is synthesized.

Detailed explanation-4: -The template strand reads AAC CT, therefore, if copied, TTG GA would result.

Detailed explanation-5: -The enzyme that converts DNA into mRNA is called RNA polymerase, which attaches to the DNA double helix as shown here. Once attached, RNA polymerase can unwind the helix and begin copying one of the DNA strands to form an mRNA transcript of the gene.
