Question

A coding strand of DNA is 5'-ATGCCGATCCAT-3'. What is the mRNA for this strand? :

a) 3'-UACGGCCUGGUA-5'
b) 5'-AUGGAUCGGACA-3'
c) 3'-TACGGCCTGGTA -5'
d) 5'-ATGCCGATCCAT-3'
e) 5'-AUGCCGAUCCAU-3'

Answer 1

The mRNA sequence for the given coding strand is 5'-AUGCCGAUCCAU-3'.

Step-by-step explanation:

The coding strand of DNA, which is read during transcription to produce mRNA, has the nucleotide sequence 5'-ATGCCGATCCAT-3'. To determine the mRNA sequence, we need to find the complementary base pairing. Adenine (A) pairs with uracil (U) in RNA, thymine (T) pairs with adenine (A) in RNA, cytosine (C) pairs with guanine (G), and guanine (G) pairs with cytosine (C). Therefore, the mRNA sequence for the given coding strand is 5'-AUGCCGAUCCAU-3'.
