Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

If one strand of DNA has the nitrogen base sequenceTACCAGAA what would be the comp, ementary (opposite) strand sequence?

A	TACCAGAA
B	AAGACCAT
C	TTCTGGTA
D	ATGGTGTT

Explanation:

Detailed explanation-1: -The base pairs on one strand of the DNA bind with the base pairs of the other strand specifically. A always pairs with T with two hydrogen bonds and G always pairs with C with three hydrogen bonds. So if one strand is ATGCTTGA then the complementary strand will be TACGAACT.

Detailed explanation-2: -Answer and Explanation: The complementary DNA strand of the sequence ATGC will be TACG.

Detailed explanation-3: -thus, the complementary one on RNA will be: UAGAC.

Detailed explanation-4: -The sequence of nitrogenous bases in one strand of DNA are 3’ TAC GCG ACG 5’ . The complementary DNA strand should have.

Detailed explanation-5: -Correct option b UAGAC ExplanationIf one strand of DNA has the nitrogenous base sequence as ATCTG the complementary sequence of mRNA will be UAGAC.
