Question

transcription and translation
what is the correct complementary nucleotide sequence for trna if the mrna nucleotide sequence is cua cca?

Explanation:

Step1: Recall base - pairing rules

In RNA, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G). For tRNA - mRNA pairing, the base - pairing is complementary.

Step2: Pair each nucleotide

Given mRNA sequence \(CUACCA\).

• For \(C\) in mRNA, \(G\) pairs in tRNA.
• For \(U\) in mRNA, \(A\) pairs in tRNA.
• For \(A\) in mRNA, \(U\) pairs in tRNA.

So, \(C
ightarrow G\), \(U
ightarrow A\), \(A
ightarrow U\), \(C
ightarrow G\), \(C
ightarrow G\), \(A
ightarrow U\)

Answer:
