Question

Here is a portion of the nucleotide sequence in phenylalanine tRNA. $$ \text { 3'-ACCACCUGCUCAGGCCUU-5' } $$ Write the nucleotide sequence of its DNA complement.

Short answer

Answer: The DNA complement of the given RNA sequence is 5'-TGGTGGACGAGTCCGGAA-3'.

Step-by-step solution

Write down the given RNA sequence

The given RNA sequence is: 3'-ACCACCUGCUCAGGCCUU-5'

Convert the RNA sequence to DNA

To find the DNA complement of the RNA sequence, we'll first convert the RNA sequence to its DNA counterpart: 3'-ACCA(CCU/GCA)TC-5' (Replace U with T)

Write the complementary DNA sequence

Now we will find the complementary DNA sequence by following the base pairing rules: For the given DNA sequence: 3'-ACCACCT/GCATC-5' The complementary DNA sequence will be: 5'-TGGTGGACGAGTCCGGAA-3' (Replace A with T, T with A, C with G, and G with C) So, the nucleotide sequence of its DNA complement is: $$ \text{5'-TGGTGGACGAGTCCGGAA-3'} $$
