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 are the three types of mutation?
The three types of mutations are substitution (a single nucleotide is replaced with a different one), insertion (an extra nucleotide is added to the DNA sequence), and deletion (a nucleotide is removed from the DNA sequence).
What is a mutation in a gene?
A permanent change in the gene's DNA sequence. Gene mutations involving one or a few nuckeotides is called point mutation. If a nucleotide is added or deleted, the bases are still read in groups of three, but now those groupings are shifted for every codon that follows. This is called frameshift mutation. Your welcome. (:
What do you think would happen if a single nucleotide were added somewhere in the sequence?
If a single nucleotide were added to a DNA sequence, it could result in a frameshift mutation, altering the reading frame of the genetic code. This change may lead to a completely different sequence of amino acids in the resulting protein, potentially affecting its function. Depending on the location and nature of the mutation, the effects could range from benign to detrimental, potentially causing disorders or diseases. In some cases, it might also have no significant effect if it occurs in a non-coding region or does not alter the protein's function.
What is a nucleotide substitution error?
Before you know what a nucleotide substitution error is, you have to know what a nucleotide is. A nucleotide holds the DNA strand together and helps make copies. When a Strand is ready to be copied, Let's say one nucleotide reads for G(Guanine), then another nucleotide would be added, which would mean C (Cytosine) would be added. A substitution error would mean that, that instead of Cytosine being added, Thymine, Adenine, Uracil, or Guanine could be added, resulting in a mutation.
During DNA replication an extra cytosine base is added to the DNA what type of mutation is this?
A frameshift mutation

During the transcription of a certain protein an extra cytosine was placed into a gene region throwing off the correct amino acid sequence what type of mutation occurred?
This is an example of an insertion mutation, where an extra nucleotide (cytosine in this case) is added to the DNA sequence during transcription, causing a shift in the reading frame and resulting in a change in the amino acid sequence of the protein being produced.

Which type of mutation results when bases added to a gene?
Frameshift ~
If a nucleotide is added or removed from a DNA molecule and mrna is created the codons after the mutation will not be read correctly this is a?
This is an example of a frameshift mutation, where the reading frame of the genetic code is shifted due to an addition or deletion of nucleotides. This can lead to a completely different sequence of codons being read during translation, potentially resulting in a non-functional protein being produced.

Frameshift
A nucleotide is about to be added to a growing strand of DNA. What factor determines which type of nucleotide will be added?
The sequence of nucleotides in the template DNA strand determines which complementary nucleotide will be added to the growing strand. A-T and G-C base pairing rules govern the selection of the nucleotide to be added during DNA replication.
Name two major types of mutations?
Frameshift mutations and Point mutations. The difference between the two are that point mutations occur at a single point in the DNA sequence and frameshift mutations shift the "reading frame" of the genetic message.
