Q. 17.114 - An Introduction to General, Organic, and Biological Chemistry

Question

What is the anticodon on tRNA for each of the following codons in an mRNA?

a. GUG b. CCC c. GAA

Step-by-Step Solution

Answer

a. In DNA, Adenine forms complimentary bonding with Thiamine (A=T), and guanine forms complimentary bonding with cytosine $(C\equiv G)$.

b. RNA contain four types of nucleotides: Guanine, Adenine, Cytosine and Uracil, and are represented by letters: G, A, C and U.

c. In DNA, Adenine forms complimentary bonding with Thiamine (A=T), and guanine forms complimentary bonding with cytosine $(C\equiv G)$.

Part(a) Step 1:Given information

We have to find out the what is the anticodon on tRNA for GUG codons in an mRNA.

Part(a) Step 2:Explanation

Each cell type contains a unique set of proteins that regulates the gene expression by controlling different levels; transcriptional level, processing level, and translational level.

RNA contain four types of nucleotides: Guanine, Adenine, Cytosine and Uracil, and are represented by letters: G, A, C and U. 

 In DNA, Adenine forms complimentary bonding with Thiamine (A=T), and guanine forms complimentary bonding with cytosine $(C\equiv G)$.

Part(b) Step 1:Given information

We have to find out the what is the anticodon on tRNA for CCC codons in an mRNA.

Part(b) Step 2:Explanation

The message identifying a specific amino acid is carried by the messenger RNA codon, while the transfer RNA transfers that amino acid to the developing protein chain. The tRNA anticodon is a three-nucleotide sequence that is the inverse of the three-nucleotide mRNA codon.

Part(c) Step 1:Given information

We have to find out the what is the anticodon on tRNA for GAA codons in an mRNA.
