What else can I help you with?
Is gene mutation and mutation is same?
Yes, gene mutation and mutation are often used interchangeably in biological contexts. Gene mutation specifically refers to a change in the sequence of DNA in a particular gene, whereas mutation can refer to changes in DNA sequences more broadly, including those not within a specific gene.
Which types of mutation affects more genes a gene mutation or a chromosomal?
a gene is passed on from generations and a chromosome is just found in certain cells
Which type of mutation will probably have a larger effect A point mutation or a frameshift?
Both types of mutation have the potential to cause a large effect.In general, a frameshift mutation is more likely to cause a large effect. This is because it shifts the 'reading frame' - so that all of the subsequent codons (groupings of 3 bases that are read to determine which amino acid will be added) will be changed.A point mutation is when a single base is replaced. This can either result in the same amino acid being added to the protein being synthesised (a silent mutation), a different amino acid being added (a missense mutation) or in a STOP codon (a nonsense mutation).If a point mutation causes a premature STOP codon - this is quite likely to have a large effect on the protein.
Which is the worse a serious error in mRNA processing for a gene or a serious mutation in the gene for transfer rna?
a serious mutation in ribosomal RNA gene is worse. the mutated ribosomes may lose their abilty to bind to messenger RNAs through Shine Dalgarno Sequences. they may also present wrongly placed E,P and A sites to the messenger RNA. this will lead to lethal results ranging from abnormal polypeptide formation to no formation at all.
What is the impact of a frameshift mutation, where one or more pairs of nucleotides are removed from a gene, on the resulting protein product?
A frameshift mutation, where nucleotides are removed from a gene, can change the reading frame of the gene. This alters the sequence of amino acids in the resulting protein, leading to a non-functional or abnormal protein. This can have serious consequences on the protein's structure and function, potentially causing genetic disorders or diseases.
When would a mutation in DNA not cause a change in how the gene is expressed or in which proteins are made?
If a point mutation occurs in a location that is not critical to the structure and function of the protein, it will not change the way the gene is expressed. Also, since most amino acids have more than one codon, if the point mutation resulted in a codon for the same amino acid without the mutation, it will not change the way the gene is expressed.
What are the two main sources of genetic variation and which of them is more common?
The two main sources of genetic variation are sexual reproduction, and mutation. Sexual reproduction is more common.
What is the purpose of genetic mapping?
Genetic mapping is mapping genes to a specific location on a chromosome. therefore the purpose is that it helps to tell where on the chromosome a mutation is. For example if scientists find were on a chromosome a gene for a certain mutation, they can conduct gene therapy to replace it with a normal version of that gene. Basically it just tells scientists the location of a mutation so they can fix it more efficiently.
Would a point mutation or a frame shift mutation more likely produce a neutral mutation?
A point shift mutation is more likely to produce a neutral reaction. This is because it involves a change in one nucleotide. A frame shift mutation is more deleterious because it involves the insertion or deletion of multiple base pairs within a gene's coding sequence.
What is a mutation of a single gene?
by what protocol we can mutate a single gene from leishmania BY ANOTHER PERSON - The answer is POINT mutation. I'm doing the worksheet too LOL hahah everyone is doing miggis homework huh === Too bad I can't find the rest of the answers for that homework D: But yea it is Point Some genetic disorders result when a mutation causes the product of a single gene to be altered or missing. ~From my science book o-o lol
A change in a population gene pool due to a chance event?
The sudden change in the genetic make up or genetic form of an individual is called gene mutation.
Why does an insertion mutation cause more defects than point mutation?
An insertion mutation adds one or more nucleotides into the DNA sequence, which can disrupt the reading frame of the gene. This frameshift can lead to the production of a completely different and often nonfunctional protein, resulting in significant defects. In contrast, a point mutation typically alters just a single nucleotide, which may only change one amino acid or have no effect at all, making it generally less disruptive than an insertion mutation. Thus, the broader impact of an insertion mutation often leads to more severe consequences in gene function.
