What else can I help you with?
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 rapid evolution can come about by the mutation of just a few genes?
Nowadays, it's called a "birth defect".
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.
The DNA of all living organisms is composed of the same what nucleotides?
The four main nucleotides are Guanine (G), Cytosine (C), Thymine (T) and Adenine (A). DNA is a universal code which means that each nucleotide will have the same meaning in almost all species. There are a few exceptions however, including Viruses with RNA genomes instead of DNA genomes. In these cases, Thymine is switched with a nucleotide called Uracil (U) and so the four nucleotides become G, C, U & A.
What determines the type of protein that is produced in protein synthesis?
This could be answered a few ways, but at the most specific, it is the codons that are translated via tRNA which make a protein. Each codon, represented by 3 nucleotides, "codes" for an amino acid. A string of amino acids make a protein, thus the nucleotides in the codons determines the product. To get to this point, requires transcription from DNA into mRNA and then mRNA is translated into the amino acids, so you could say that DNA itself determines the protein produced; however, it is actually the codons in the mRNA that are used to make the protein. The section of DNA that is transcribed is called a gene, so you could also say that it is the gene that determines what is produced.
Mutation that involves a single nucleotide is called?
Point Mutation is the mutation that involves a single or few nucleotide. This type of mutation replaces a single nucleotide to another.

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.
Could a mutation in a cell in the liver of a human be passed on?
For a mutation to be passed onto the next generation it must be on sex chromosome. If mutation occurs in somatic cells of our body, it will not be passed on to the offspring(s). Mutation that changes one or few base pairs in the DNA is called point mutation.
What is the rapid evolution can come about by mutation of just a few genes?
Nowadays, it's called a "birth defect".
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 can mutation lead to?
There are a few activities that are unsafe because they lead to dismemberment and mutation of the body. Playing with guns and or hunting can lead to mutation or dismemberment.
What Activities can lead to mutation?
There are a few activities that are unsafe because they lead to dismemberment and mutation of the body. Playing with guns and or hunting can lead to mutation or dismemberment.
Which mutation provides a survival advantage?
There are quite a few mutations that provide a variety of survival advantages to animals. One mutation is bigger wing span.
What is the rapid evolution that can come about by the mutation of just a few genes'?
Punctuated equilibrium
Is there a white Bengal tiger?
Yes, there are a few. They are considered to be expression of a mutation in the coat color.
When does the mutation occur?
Every few hundred millenia Source: X-Men: The Movie
