Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Transcribe the following DNA sequence to the complementary mRNA sequence. TAC CGG CTG
A
AUG GCC GAC
B
AUG GCC GAG
C
AUG CGG GAC
D
GUA GCC GAC
Explanation: 

Detailed explanation-1: -This leads to a total of 10 codons in the mRNA sequence AUGGCAGUGCCA as AUG, UGG, GGC, GCA, CAG, AGU, GUG, UGC, GCC, CCA.

Detailed explanation-2: -Steps for Writing Complementary DNA Sequences Step 1: Starting on the left, read the first letter in the DNA sequence and write down the complementary base. Step 2: Continue from left to right until the complementary sequence is complete.

Detailed explanation-3: -Answer and Explanation: The complementary DNA strand of the sequence ATGC will be TACG. The complementary base pairing in DNA is as per the Chargaff’s rules. According to these rules, purines always hydrogen bond with pyrimidines and vice-versa.
