Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Transcribe the following sequence of DNA into RNA:AAG CTT TGC
A
TTC GAA ACG
B
UUC GAA ACG
C
TTC GUU UCG
D
UUC GUU UCG
Explanation: 

Detailed explanation-1: -It involves copying a gene’s DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination.

Detailed explanation-2: -The major steps of transcription are initiation, promoter clearance, elongation, and termination.

Detailed explanation-3: -This leads to a total of 10 codons in the mRNA sequence AUGGCAGUGCCA as AUG, UGG, GGC, GCA, CAG, AGU, GUG, UGC, GCC, CCA.
