DNA MAKES RNA MAKES PROTEIN

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What would be the resulting mRNA strand made in transcription from the following DNA segment:ATA CGC AGT
A
TAT GCG TCA
B
ATA CGC AGT
C
UAU GCG UCA
D
UAT GCG AGT
Explanation: 

Detailed explanation-1: -Template strand is the DNA strand off which the mRNA is synthesized. The coding, or non-template, strand is the DNA strand complementary to the template strand; it has the same sequence (except for T for U substitutions) as the mRNA.

Detailed explanation-2: -In order to determine the gene sequence based off an mRNA template, you can simply do the reverse. You would match up DNA nucleotides with the complementary RNA nucleotides. You can also determine the sequence of the coding strand of DNA by simply changing the RNA U’s into DNA T’s.

Detailed explanation-3: -One strand of the given DNA segment codes for mRNA having the sequence AUC GCG UCA for the synthesis of protein.
