Study Notes
Mutation Types
Frameshift Mutation
- A type of mutation that occurs when there is an insertion or deletion of one or more nucleotides in a DNA sequence
- Results in a change in the reading frame of the genetic code
- Can lead to the creation of a completely new sequence of amino acids in a protein
- Often results in a non-functional protein or a protein with a different function
Point Mutation
- A type of mutation that involves a change in a single nucleotide base in a DNA sequence
- Can be classified as:
- Silent mutation: no effect on the amino acid sequence
- Missense mutation: changes the amino acid sequence
- Nonsense mutation: leads to a premature stop codon
- Can result in a change to the function of a protein or the creation of a new protein
Chromosomal Mutation
- A type of mutation that involves changes to the number or structure of chromosomes
- Can be classified as:
- Numerical mutations: changes in the number of chromosomes (e.g. aneuploidy, polyploidy)
- Structural mutations: changes in the structure of a chromosome (e.g. deletions, duplications, translocations)
- Can result in changes to the expression of genes or the creation of new proteins
Gene Mutation
- A type of mutation that involves a change to a gene or its regulatory elements
- Can affect the expression of a gene, leading to changes in the production of a protein
- Can result in a change to the function of a protein or the creation of a new protein
Spontaneous Mutation
- A type of mutation that occurs naturally, without the influence of external factors
- Can occur due to errors in DNA replication or repair
- Can result in changes to the function of a protein or the creation of a new protein
Note: These notes provide a brief overview of the different types of mutations. Each type of mutation can have significant effects on the function of proteins and the expression of genes.
Mutation Types
Frameshift Mutation
- Occurs when there is an insertion or deletion of one or more nucleotides in a DNA sequence
- Results in a change in the reading frame of the genetic code
- Can lead to the creation of a completely new sequence of amino acids in a protein
- Often results in a non-functional protein or a protein with a different function
Point Mutation
- Involves a change in a single nucleotide base in a DNA sequence
- Can be classified as:
- Silent mutation: no effect on the amino acid sequence
- Missense mutation: changes the amino acid sequence
- Nonsense mutation: leads to a premature stop codon
- Can result in a change to the function of a protein or the creation of a new protein
Chromosomal Mutation
- Involves changes to the number or structure of chromosomes
- Can be classified as:
- Numerical mutations: changes in the number of chromosomes (e.g. aneuploidy, polyploidy)
- Structural mutations: changes in the structure of a chromosome (e.g. deletions, duplications, translocations)
- Can result in changes to the expression of genes or the creation of new proteins
Gene Mutation
- Involves a change to a gene or its regulatory elements
- Can affect the expression of a gene, leading to changes in the production of a protein
- Can result in a change to the function of a protein or the creation of a new protein
