Capitolo 7, Problema 2
A triplet of mRNA nucleotides that specifies a particular amino acid is called a ____________ .
Guida verificata passo dopo passo1
Understand that in molecular biology, the sequence of nucleotides in mRNA is read in groups of three bases.
Each group of three nucleotides in mRNA is known as a codon.
A codon corresponds to a specific amino acid or a stop signal during protein synthesis.
Therefore, the triplet of mRNA nucleotides that specifies a particular amino acid is called a codon.
This concept is fundamental to the genetic code and how proteins are synthesized in cells.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Codon
A codon is a sequence of three nucleotides on an mRNA molecule that corresponds to a specific amino acid or a stop signal during protein synthesis. Each codon directs the addition of a particular amino acid to a growing polypeptide chain.

How to Use the Genetic Code
mRNA (messenger RNA)
mRNA is a type of RNA that carries genetic information transcribed from DNA in the form of codons. It serves as a template for protein synthesis by providing the sequence of codons that determine the amino acid order.

Genetic Code
The genetic code is the set of rules by which the sequence of nucleotides in mRNA is translated into the sequence of amino acids in proteins. It is nearly universal and consists of codons, each specifying one amino acid or a stop signal.
