What type of mutation will the deletion of a DNA nucleotide from a strand of DNA cause?
The DNA sequence of a gene can be altered in a number of ways. Gene mutations have varying effects on health, depending on where they occur and whether they alter the function of essential proteins.
The types of mutations include: missense mutation, nonsense mutation, insertion, deletion, duplication, frameshift mutation or repeat expansion.
A deletion changes the number of DNA bases by removing a piece of DNA. Small deletions may remove one or a few base pairs within a gene, while larger deletions can remove an entire gene or several neighboring genes. The deleted DNA may alter the function of the resulting protein(s).

What type of mutation when a nucleotide is dropped from a DNA sequence?
A deletion mutation occurs when a nucleotide is dropped from a DNA sequence. This can cause a shift in the reading frame, leading to a non-functional protein being produced.
How many nucleotides would cause a frame shift mutation?
Adding or subtracting just one nucleotide would cause a frame shift mutation.
Can a point mutation cause a change in one single nucleotide in a DNA sequence?
Yes, a point mutation can cause a change in one single nucleotide in a DNA sequence.
What happens in deletion mutation?
"A type of gene mutation wherein the deletion (as well as addition) of (a number of) nucleotide(s) causes a shift in the reading frame of the codons in the mRNA, thus, may eventually lead to the alteration in the amino acid sequence at protein translation."
Mutations that change one or just a few of nucleotides in a gene on a chromosome are called what?
the correct answer is C. a substitution i know this cause i have this book to this question and point mutation is not one of the answer and i found the answer in the book -No its substituton you jack wagon your books wrong

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.
Can a point mutation cause a change in one single nucleotide in a DNA sequence?
Yes, a point mutation can cause a change in one single nucleotide in a DNA sequence.
What are the three ways chromosomes can cause mutations?
point mutation, insertion and deletion

A mutation that causes antibiotic resistance in bacteria is a what mutation?
Missense mutation Nonsense mutation Frameshift insertion Frameshift deletion All may cause antibiotic resistance in bacteria
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.

Why does a deletion mutation cause more defects than a point mutation?
A deletion mutation removes one or more nucleotides from the DNA sequence, potentially disrupting the reading frame of the gene, which can lead to a completely nonfunctional protein. This frame shift can affect all downstream amino acids, resulting in significant changes or loss of function. In contrast, a point mutation typically alters only a single nucleotide, which may lead to a missense mutation (changing one amino acid) or a silent mutation (no change in amino acid). Therefore, deletions often have a more drastic impact on protein structure and function compared to point mutations.
What nucleotide could be included in the sequence agatgcgagttacgg to form a genetic mutation?
The nucleotide sequence should be AGA TGC GAG TTA CGG (all upper case). AGA TGC GAG TTA CGG (first strand) on DNA TCT, ACG, CTC, AAT, GCC (complementary strand) to the above DNA mRNA: UGU,UGC,GUG,UUA,CGG producing these amino acids:cytoseine, cytosine, valine and arginine. Adding an adenine could cause a mutation at the second codon (stop).
Which do you suppose would be more harmful A mutation that changed the nucleotide sequence of an mRNA molecule or a mutation that changed the nucleotide sequence of a DNA molecule?
A mutation in a DNA nucleotide sequence would be more harmful than a mutation in a mRNA nucleotide sequence because it could cause the synthesis of multiple nonfunctional proteins in comparison to a mutation in a mRNA nucleotide sequence that would be less harmful because it would result in a few nonfunctional proteins.
