Causes a shift in the reading codons by one base?
A frameshift mutation is caused by the insertion or deletion of a nucleotide in the DNA sequence, leading to a change in the reading frame of codons. This can result in a completely different protein being produced from the altered sequence, affecting the functionality of the protein.
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.
Changes in a DNA sequence caused by substitution of one nucleotide for another?
A substitution mutation occurs when one nucleotide in a DNA sequence is replaced with a different nucleotide. This can lead to a change in the corresponding amino acid in the protein produced from that gene, potentially altering the protein's structure and function. Substitution mutations can be silent (no change in the amino acid), missense (change in one amino acid), or nonsense (premature stop codon).
What type of mutation in the DNA leads to a single change in the amino acid sequence of the protein?
Yes, it already has by changing the amino acid you have a mutation. That one amino acid counld be in the active site of an enzyme and that one amino acid being changed could result in loss of function or reduction in function of the enzyme. Sickle cell animea is caused by a single such amino acid substiution.
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.
Suppose part of an amino acid sequence of a protein changed from tyrosine proline glycine alanine to tyrosine histidine glycine alanine this change was most likely caused by a point mutation called?
This change was most likely caused by a point mutation called a missense mutation. Missense mutations involve the substitution of a single nucleotide in the DNA sequence, leading to a change in one amino acid in the protein sequence. In this case, the substitution of a single nucleotide led to the change from tyrosine to histidine in the protein 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.
What is a change in nucleotide-base sequence of a gene or DNA molecule?
A change in the nucleotide base sequence of a gene or DNA molecule is known as a mutation. Mutations can be caused by various factors such as errors during DNA replication, exposure to mutagens like UV radiation or chemicals, or genetic predisposition. These changes can alter the functioning of the gene or protein it codes for, which may lead to genetic disorders or diseases.

A change in a sequence of DNA is called?
Any change in the sequence of DNA nucleotides is called mutation.
A nucleotide sequence changes from attcgg to atcgg what type of mutation occurred?
There are 3 types of mutations that are possible. Insertion Substitution Deletion If we use a bit of logic and knowledge to figure out what each action does, then we can find out the answer. Insertion will the Insert. Substitution will be Substitute. Deletion will be Delete. To insert would mean to put into. To substitute would mean to replace. To delete would mean to take away. Using that knowledge we can assume that the type of mutation that occurred is deletion.
How are point mutations different from flame shift mutations?
Point mutations are when a single nucleotide is replaced by a different one, but this doesn't affect the length of the DNA sequence, which usually will not affect the way the protein that is produced. A phase shift (what I think you meant) mutation is caused by an addition or deletion of a base that changes the length of the sequence. This causes problems because codons to make proteins are in sets of 3 and deleting a nucleotide makes the reading frame different and will add incorrect amino acids to the proteins from the mutation on, resulting in an ineffective protein.
What type of mutation in the DNA leads to a single change in the amino acid sequence of the protein?
Yes, it already has by changing the amino acid you have a mutation. That one amino acid counld be in the active site of an enzyme and that one amino acid being changed could result in loss of function or reduction in function of the enzyme.

Can a change in a nucleotide cause a disease?
By changing a gene's instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. So, yes.
