Mutations and Protein Synthesis

Front

What is a point mutation?

Back

A point mutation is a change in a single nucleotide base in the DNA sequence, which can result in a substitution of one amino acid for another in a protein.

Front

What is another name for a point mutation?

Back

Substitution.

Front

What are the possible results of mutations?

Back

Mutations can lead to changes in DNA sequence, genetic variation in a species, and differing amino acid sequences.

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when nucleotides are inserted or deleted from the DNA sequence, altering the reading frame of the genetic code.

Front

What is a deletion mutation?

Back

A deletion mutation is a type of frameshift mutation where one or more nucleotide bases are removed from the DNA sequence.

Front

Identify the deletion mutation from the following: ATG CCA AAT.

Back

ATC CA AT.

Front

What are the building blocks of proteins called?

Back

Amino Acids.

Front

What is the role of amino acids in protein synthesis?

Back

Amino acids are linked together in a specific sequence to form proteins, which perform various functions in the body.

Front

What is the difference between a substitution mutation and a frameshift mutation?

Back

A substitution mutation replaces one nucleotide with another, while a frameshift mutation involves the insertion or deletion of nucleotides, shifting the reading frame.

Front

What is the significance of mutations in evolution?

Back

Mutations introduce genetic variation, which is essential for evolution as it provides raw material for natural selection.
