What is the difference between nucleotide deletion and nucleotide insertion?
Here's a sample nucleotide sequence:AATUGCIf there was a nucleotide deletion (let's say the "G" gets deleted), the sequence would become:AATUCIf there was a nucleotide addition/insertion (let's say a "G" was added between "T' and "U"), the sequence would become:AATGUGCThe difference is that a deletion makes the DNA shorter and an insertion makes it longer.
What type of mutation results when nucleotide is dropped from a DNA sequence?
deletion
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 a loss of complete chromosome called?
deletion-occurs when an end of a chromosome breaks off or when two simultaneous breaks lead to the loss of an internal segment
What are the types of genetic mutations?
1. Insertion- when a nucleotide gets added to the DNA strand2. Substitution- when a nucleotide gets replaced on the DNA strand3. Deletion- when a nucleotide gets deleted from the DNA strandThose are all of the DNA mutation types. Hoped this really helped you out

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.

What is an example of how an enzyme can lead to changes in gene expression and phenotype?
if the coding for an enzyme is not correct due to a deletion or insertion of a nucleotide, this could cause for a noncoding gene of an enzyme needed to complete expression of a certain gene(relating to phenotype, or what someone looks like) it could be more serious, enzymes are needed to complete reactions, without enzymes no reactions and things don't function properly.
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.
What is the difference between a point mutation and an insertion and deletion?
Because a point mutation is the replacement of a single base with another base. Thus, if the replacement base codes for the same type amino acid, such as a hydrophobic type amino acid replacing a hydrophobic amino acid, no change to the protein coded for will occur. If a deletion mutation occurs then the code for the protein is disrupted and the protein product is probably going to be useless to the body and may even cause a disease.
