Mutations that change one or just a few of nucleotides in a gene on a chromosome are called what?
the correct answer is C. a substitution i know this cause i have this book to this question and point mutation is not one of the answer and i found the answer in the book -No its substituton you jack wagon your books wrong
A mutation that involves a single nucleotide is called a(an)?
Point Mutation- a type of gene mutation in which only a single nucleotide in a gene has been changed.
Mutations that occur at one single nitrogen base are referred to as?
Mutations that occur at one single nitrogen base are referred to as a point mutation.
True or false a point mutation is the failure of a chromosome pair to separate during mitosis?
false, point mutation is the change in any single base within DNA at a given time.it occurs only once during a single mutation
A mutation in which a single base is added to or deleted from DNA is called what?
translocation .. this is wrong.its a point mutation :)
The substitution addition or removal of a single nucleotide in DNA is called a what mutation?
point mutation
A change in a single nucleotide in DNA-?
A mutation
Is galactosemia a frameshift mutation insertion mutation or substitution mutation?
There are 5 different disorders that result in galactosemia differentiated into three main types. The worst is the Classic form and there are over 180 different mutations associated with this form. The GALT gene is modified by substitution is these examples. The most common one in Caucasian is a single substitution of arginine for glutamine at position 188 on the protein. Another mutation that occurs almost exclusively in individuals of African decent is a single substitution of leucine for serine at position 135.
Which types of mutation causes sickle cell anemia?
No single mutation is responsible for this disease. It just happens by abnormality in the red blood cells. It affects the hemoglobin.

What type of mutation causes sickle cell anemia substitution deletion insertion mutagen?
The type of mutation that causes a defect in the gene (causing sickle cell anaemia) is a substitution mutation.A single nucleotide substitution (A to T) in the β-globin gene causes the amino acid valine to replace glutamic acid. This changes the resulting protein, causing a haemoglobin with an abnormal shape to be created.
What kind of mutation will result from the mistake made during DNA replication in the nucleotide sequence above?
The specific type of mutation resulting from a mistake during DNA replication will depend on the nature of the mistake and the type of nucleotide substitution that occurred. Some possible types of mutations include point mutations (such as a substitution, insertion, or deletion of a single nucleotide), frameshift mutations, or silent mutations.
A change in a single DNA nucleotide is called?
Yes but Mutation point 😂 A. Point Mutation
Mutation that involves a single nucleotide is called?
Point Mutation is the mutation that involves a single or few nucleotide. This type of mutation replaces a single nucleotide to another.
What would a single change in the sequence of nitrogenous bases in a DNA molecule most likely result in?
A mutation
What occur at single point in DNA sequence?
At single point or a single base, many things can happen.If it is changed by any chance (mutation) it may cause deleterious effect (a disease like sickle cell anemia). Single point may act as a singnal for a protein to bind and activate a biochemical process. It also do act as a splicing signal.
A mutation that involves a single nucleotide is called a(an)?
Point Mutation- a type of gene mutation in which only a single nucleotide in a gene has been changed.
