If one nucleotide is replaced by another it is called?
If one nucleotide is replaced by another, it is called a point mutation. This type of mutation involves a change in a single nucleotide within the DNA sequence.
What is a point mutuation?
A point mutation is a type of genetic mutation that involves a change in a single nucleotide base pair in DNA. This can result in the substitution of one nucleotide for another, the insertion of an extra nucleotide, or the deletion of a nucleotide. Point mutations can lead to changes in the amino acid sequence of a protein, which can affect its structure and function.
How did substitution mutation get its name?
Substitution mutations are named for the process by which one nucleotide in the DNA sequence is replaced or "substituted" with another nucleotide. This change can result in a different amino acid being incorporated into a protein or may have no effect at all, depending on the nature of the substitution. The term highlights the specific alteration of a single base pair without the insertion or deletion of additional nucleotides.
A change in which part of a gene is the result of a mutation?
A mutation can result in a change in the DNA sequence of a gene. This can involve a substitution of one nucleotide for another, an insertion or deletion of nucleotides, or rearrangement of the existing nucleotides. These changes can alter the protein produced by the gene and may lead to genetic disorders or other consequences.
What are the three types of mutation?
The three types of mutations are substitution (a single nucleotide is replaced with a different one), insertion (an extra nucleotide is added to the DNA sequence), and deletion (a nucleotide is removed from the DNA sequence).
If one nucleotide is replaced by another it is called?
If one nucleotide is replaced by another, it is called a point mutation. This type of mutation involves a change in a single nucleotide within the DNA sequence.
How are substitution mutations caused?
Substitution mutations are typically caused by errors during DNA replication, where a wrong nucleotide is incorporated into the DNA sequence. This can also be caused by exposure to mutagens, such as certain chemicals or radiation, which can lead to changes in the DNA nucleotide sequence.
Is substitution a type of gene mutation?
Yes, substitution is a type of gene mutation where one nucleotide is replaced by another in the DNA sequence.
Which mutation occurs when one nucleotide is replaced with another base?
Substitution

What is one example of a substitution mutation?
One common example of a substitution mutation is a point mutation where one nucleotide base is replaced by another. This can lead to changes in the amino acid sequence of a protein during translation. An example would be a mutation where a Cytosine (C) is substituted for a Thymine (T) in the DNA sequence.
Which mutation occurs when one nucleotide base in replaced with another base?
A point mutation occurs when one nucleotide base is replaced with another base. This can lead to changes in the amino acid sequence during protein synthesis, potentially affecting the protein's function.

What is point mutation substitution?
When a nitrogen base is substituted for a different one so it may code for a different amino acid. Sometimes substitution still codes for a same amino acid, in which case it becomes a silent mutation, but in other times it may alter the protein entirely.
What are the three types of mutation?
The three types of mutations are substitution (a single nucleotide is replaced with a different one), insertion (an extra nucleotide is added to the DNA sequence), and deletion (a nucleotide is removed from the DNA sequence).
What describes a substitution mutation and how does it impact the genetic code?
A substitution mutation is a type of genetic mutation where one nucleotide is replaced by another in the DNA sequence. This can lead to a change in the amino acid sequence during protein synthesis, which can alter the function of the protein produced. The impact of a substitution mutation on the genetic code depends on where it occurs in the DNA sequence and what amino acid is substituted, which can result in a variety of effects ranging from no change to a significant alteration in the protein's function.
