Chapter 24, Problem 112A

Interpretation Introduction

Interpretation : The base sequence for the amino acid sequence Trp-Met-Leu is to be interpreted.

Concept Introduction : The building blocks of proteins are amino acids, which are the chemical compounds that come together to make proteins. These biomolecules are essential for human growth and development and are engaged in a number of biological and chemical processes in the body.

Answer to Problem 112A

The base sequence for sequence Trp-Met-Leu is uncertain due to the possibility of six codes for Leucine.

Explanation of Solution

The formation and maintenance of the body's proteins, muscles, enzymes, and neurotransmitters depend on the amino acid tryptophan, which is also necessary for infants' optimal growth.

Tryptophan is an essential amino acid.

Meat, fish, and dairy items all contain methionine, an essential amino acid.

According to the table, tryptophan (Trp) is coded as ACC.

According to the table, methionine (Met) is coded as TAC.

Here, A stands for adenine, C stands for cytosine, T for thymine.

The gene code for the DNA combination Trp-Met-Met is ACC-TAC-TAC.

One of the three necessary branched-chain amino acids is leucine (BCAAs).

Skeletal muscles can utilize these amino acids to provide energy during exercise.

According to the table, leucine (Leu) can be coded as AAT, AAC, GAA, GAG, GAT and GAC.

Here, A stands for adenine, C stands for cytosine, T stands for thymine, and G stands for guanine.

There are six codes for leucine.

The gene code for DNA combination Trp-Met-Leucine gives a number of codes and it is uncertain to determine it.
