Which genetic change is best described by the following statement A random change in the base sequence of DNA results in an alteration of a polypeptide?
A point mutation is best described by this statement. Point mutations occur when there is a change in a single nucleotide base in the DNA sequence, which can lead to changes in the corresponding amino acid sequence of a polypeptide during protein synthesis.
A change in DNA is?
A change in DNA is known as a mutation, which is a alteration in the nucleotide sequence of a gene. Mutations can be caused by various factors such as errors in DNA replication, exposure to radiation or chemicals, and environmental factors. Mutations can have positive, negative, or neutral effects on an organism's traits and evolution.
How is it possible for gene with a mutation in coding region to encode a polypeptide with the same amino acid sequence as the nonmutant gene?
If the mutant codon still codes for the same amino acid (a silent mutation). For example: GUU, GUC, GUA and GUG all code for the amino acid Valine. So if the mutation changed the codon from GUU to GUA - Valine would still be produced and therefore the polypeptide will be identical.
Mutation is any change in a gene or chromosome?
mutations
A change in DNA sequence caused by a mistake in DNA replication or exposure to radiation or chemicals?
A mutation is a change in the DNA sequence that can occur due to errors in DNA replication, exposure to radiation, or chemicals. Mutations can have various effects on an organism, such as causing genetic disorders or contributing to evolutionary changes.
What function does mutation commonly mess up?
suddenly drastic change in the function of an organ of the body
Which genetic change is best described by the following statement A random change in the base sequence of DNA results in an alteration of a polypeptide?
A point mutation is best described by this statement. Point mutations occur when there is a change in a single nucleotide base in the DNA sequence, which can lead to changes in the corresponding amino acid sequence of a polypeptide during protein synthesis.
What is the term for any permanent change in a gene of chromosome?
A mutation is the term for any permanent change in a gene or chromosome. Mutations can be caused by various factors, such as errors during DNA replication or exposure to certain environmental factors like radiation or chemicals.
A change in a sequence of DNA is called?
Any change in the sequence of DNA nucleotides is called mutation.
What is a Missence mutation?
A mutation that causes the code for the wrong amino acid (apexvs.com)
What group who favored drastic change?
Anarchists favored drastic change.
What group favored drastic change?
Anarchists favored drastic change.
What genetic disease may be caused by a change or mutation in the hemoglobin gene?
sickle-cell anemia.
A change in DNA is?
A change in DNA is known as a mutation, which is a alteration in the nucleotide sequence of a gene. Mutations can be caused by various factors such as errors in DNA replication, exposure to radiation or chemicals, and environmental factors. Mutations can have positive, negative, or neutral effects on an organism's traits and evolution.
What mutation can change every amino acid that follows the point of mutation?
A frameshift mutation, where an insertion or deletion of nucleotides causes a shift in the reading frame of the genetic code, can change every amino acid that follows the point of mutation. This can have dramatic effects on the resulting protein's structure and function.
What name do scientists use to describe a change in a gene?
Scientists use the term "mutation" to describe a change in a gene. Mutations can be caused by various factors and can result in a range of effects, from no noticeable change to significant alterations in the organism's characteristics.
What is the sudden change in a gene called?
A sudden change in a gene is called a mutation. Mutations can be caused by various factors, such as errors during DNA replication or exposure to mutagenic agents like radiation or certain chemicals. Mutations can have a range of effects, from being harmless to causing genetic disorders or diseases.
