Protein Synthesis and Mutations

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base.

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 is a substitution mutation?

Back

A substitution mutation is a type of mutation where one nucleotide base is replaced by another, potentially altering one amino acid in a protein.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when nucleotides are inserted or deleted from the DNA sequence, changing the reading frame and affecting all subsequent amino acids.

Front

What are amino acids?

Back

Amino acids are organic compounds that combine to form proteins; they are the building blocks of proteins.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are cellular structures that facilitate the translation of mRNA into proteins by linking amino acids together.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically mRNA, which carries the genetic information to the ribosome.

Front

What is translation?

Back

Translation is the process by which ribosomes synthesize proteins using the information encoded in mRNA.

Front

What is the Central Dogma of molecular biology?

Back

The Central Dogma describes the flow of genetic information from DNA to RNA to protein.

Front

What is a gamete?

Back

A gamete is a sex cell, such as a sperm or egg, that carries half the genetic information of an organism.
