Protein Synthesis & Mutations

Front

What is protein synthesis?

Back

The process by which cells generate new proteins, involving transcription of DNA to mRNA and translation of mRNA to amino acids.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where it serves as a template for protein synthesis.

Front

What are amino acids?

Back

Amino acids are organic compounds that serve as the building blocks of proteins. There are 20 different amino acids.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or stop signal during protein synthesis.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in the structure and function of proteins.

Front

What are the types of mutations?

Back

The main types of mutations are substitution, insertion, deletion, and translocation.

Front

What is a substitution mutation?

Back

A substitution mutation occurs when one nucleotide in the DNA sequence is replaced by another, potentially altering the amino acid sequence.

Front

What is an insertion mutation?

Back

An insertion mutation involves the addition of one or more nucleotides into a DNA sequence, which can disrupt the reading frame.

Front

What is a deletion mutation?

Back

A deletion mutation occurs when one or more nucleotides are removed from a DNA sequence, potentially leading to a frameshift.

Front

What is translocation in genetics?

Back

Translocation is a mutation where a segment of DNA is moved from one location to another, which can affect gene expression.
