Chapter 28: Problem 31

Write the mRNA complement for \(5^{\prime}\)-TCAACGAT-3'.

Short Answer

Expert verified
Answer: The mRNA complement for the given DNA sequence is 5'-AGU UGC UA-3'.

Step by step solution

01

Determine complementary mRNA bases for each DNA base

For each base in the given DNA sequence, find its complementary mRNA base according to the base-pairing rules: - Adenine (A) pairs with uracil (U) - Thymine (T) pairs with adenine (A) - Cytosine (C) pairs with guanine (G) - Guanine (G) pairs with cytosine (C)
02

Write the mRNA complement

Replace each base in the DNA sequence with its complementary mRNA base: 5'-TCAACGAT-3' 5'-AGUUGCUA-3' By applying the base-pairing rules, we find the mRNA complement for the given DNA sequence is 5'-AGU UGC UA-3'.
