Question

A DNA template strand contains the following sequence:
5'\text{ AGGCTCCAG }3'5
′
AGGCTCCAG 3
′
5, prime, start text, space, A, G, G, C, T, C, C, A, G, space, end text, 3, prime
Which complementary RNA strand can be made from this sequence?
Choose 1 answer:

Answer 1

Answer: Though the answer were not given, the complementary RNA strand is 5'UCCGAGGUC3'

Explanation: RNA is a single stranded nucleic acid produced from DNA. Four bases are usually found in DNA and they include adenine, Uracil, cytosine and guanine whereas adenine, thymine, cytosine and guanine are found in DNA. In RNA base pairing, wherever adenine is found in the DNA template strand, uracil occurs in the RNA strand, wherever thymine is found in the DNA template strand, adenine occurs in the RNA strand and anywhere cytosine occurs in the DNA template strand, guanine occurs in the RNA strand. This means that adenine pairs with uracil, cytosine pairs with guanine and thymine pairs with adenine.
