Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What would be the complementary DNA strand to the given strand of ATCGTA
A
GCATCG
B
TAGCAT
C
ATGCTA
D
CATGAC
Explanation: 

Detailed explanation-1: -If one strand of DNA has the base sequence ATCGTA the complementary strand would be TAGCAT as A and T pair and C and G pair.

Detailed explanation-2: -The correct option is C The complementary DNA strand of the sequence ATGC will be TACG. The complementary base pairing in DNA is as per the Chargaff’s rules.

Detailed explanation-3: -noun Biochemistry. either of the two chains that make up a double helix of DNA, with corresponding positions on the two chains being composed of a pair of complementary bases. a section of one nucleic acid chain that is bonded to another by a sequence of base pairs.

Detailed explanation-4: -Step 1: Starting on the left, read the first letter in the DNA sequence and write down the complementary base. The first base in this sequence is “A", which pairs with “T", so the first letter in our complementary sequence will be “T". Step 2: Continue from left to right until the complementary sequence is complete.
