If a nucleotide pair were removed from a gene what would be affected?
If a nucleotide pair were to be removed from a gene, it would cause a frameshift mutation. This would alter the reading frame of the gene, leading to a change in the amino acid sequence of the protein encoded by that gene. This could potentially result in a nonfunctional or altered protein.
A change in a single nucleotide in DNA-?
A mutation
Most common modification in gene structure in the human genome?
Single nucleotide polymorphisms (SNPs) are the most common modification in the human genome. These are variations at a single DNA base pair that occur in at least 1% of the population. SNPs can impact gene function and contribute to traits and diseases.
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.
What is the point mutation of AGGCGTCCATGA?
A point mutation refers to a change in a single nucleotide in a DNA sequence. In the sequence AGGCGTCCATGA, any alteration of a single base pair would qualify as a point mutation. For example, if the first 'G' were replaced with an 'A', the mutated sequence would be AGGCGTCCATGA → AAGCGTCCATGA.

What are types of point mutation?
The types of point mutations are: base-pair substitution, insertions, deletions, and frameshift mutations. In base-pair substitution, one nucleotide and its corresponding partner are replaced with another pair of nucleotide. In insertion, nucleotide pairs are added to a gene. In deletion, nucleotide pairs are taken out of a gene. Frameshift mutation happens as a result of insertion or deletion when more or less than three (or a multiple of three) nucleotide pairs are added to or taken from a gene.
True or false a point mutation is the failure of a chromosome pair to separate during mitosis?
False. A point mutation is a change in a single nucleotide of DNA, leading to a change in the protein encoded by that gene. The failure of a chromosome pair to separate during mitosis is known as nondisjunction, which can lead to chromosomal abnormalities in the daughter cells.

A point mutation involves a change in an?
A point mutation is a genetic mutation when a wrong nucleotide bonded to DNA during replication. Usually, DNA polymerase can prevent that because it's an enzyme that finds the right nucleotides to bond to new DNA strands.
How does a base pair substitution affect the genetic code?
A base pair substitution in the genetic code can change a single nucleotide in the DNA sequence, potentially leading to a different amino acid being incorporated into a protein during translation. This can result in a different protein being produced, which may affect the function of the gene and potentially lead to genetic disorders or changes in an organism's traits.

What are nucleotides pair substitution?
Nucleotide pair substitution is a type of mutation where one nucleotide in a DNA sequence is replaced by another nucleotide. This can lead to changes in the protein encoded by the gene, potentially altering its function. Substitutions can be classified as silent (no effect on protein), missense (changes one amino acid), or nonsense (creates a premature stop codon). These mutations can arise from errors during DNA replication or environmental factors.
What are the building blocks of a nucleotide?
A nucleotide consists of a base pair ( A with T, C with G) with a sugar phospate molecule
Each gene of a gene pair is an?
allele
