Question

question 20 of 50
which strand of mrna would be made during transcription using the dna strand shown below?
gat ccg
a. gtu ggc
b. cua ggc
c. cta ggc
d. gat ccg

Explanation:

Step1: Understand base - pairing rules

In transcription, DNA bases pair with RNA bases. DNA has A (adenine), T (thymine), C (cytosine), G (guanine). RNA has A, U (uracil), C, G. The base - pairing rules are A - U and T - A, C - G, G - C.

Step2: Apply rules to each base

For the DNA strand "GAT CCG":

• G (DNA) pairs with C (RNA), A (DNA) pairs with U (RNA), T (DNA) pairs with A (RNA), C (DNA) pairs with G (RNA), C (DNA) pairs with G (RNA), G (DNA) pairs with C (RNA).

So the mRNA strand is "CUA GGC".

Answer:

B. CUA GGC
