Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the complementary strand for the following sequence:ATG TGA CAG
A
ATG TGA CAG
B
TAC ACT GTC
C
GTA AGT GAC
D
CAT TCA CTG
Explanation: 

Detailed explanation-1: -Answer and Explanation: If a DNA strand has the sequence 5’-ATG-3’, the complementary messenger RNA (mRNA) sequence made using this DNA template would have the sequence 3’-UAC-5’.

Detailed explanation-2: -Complementary sequence: Nucleic acid sequence of bases that can form a double-stranded structure by matching base pairs. For example, the complementary sequence to C-A-T-G (where each letter stands for one of the bases in DNA) is G-T-A-C.

Detailed explanation-3: -The reverse complement of a DNA sequence is formed by reversing the letters, interchanging A and T and interchanging C and G. Thus the reverse complement of ACCTGAG is CTCAGGT. What is a genome?

Detailed explanation-4: -Two strands are considered complementary if each nucleotide in one strand can form a pair with the corresponding nucleotide in the other strand. For example, AACG is complementary with TTGC.
