Which mutation cannot occur in a tRNA encoding gene?
A mutation that changes the start codon of a tRNA gene is unlikely to occur, as that could prevent proper translation of the tRNA. Mutations that disrupt critical structural elements such as the anticodon loop or the acceptor stem are also less likely, as they would affect the tRNA's functionality.
If an enzyme is absent during polypeptide production a mutation can occur?
Yes, if an enzyme necessary for polypeptide production is absent, the process may be disrupted. This could potentially lead to errors in translation, such as misincorporation of incorrect amino acids, which can result in a mutation in the polypeptide sequence.
Explain how a mutation could have no effect on the organism?
It can have absolutely no affect, a bad affect, or even a good affect.*Deletion and Addition are frameshift: most harmful.
What will mutation do if it does not occur in sex cells?
Mutations which do not occur in sex cells are not passed on to the next generation. The mutation will only affect the individual. They could therefore have normal offspring.
What type of mutation could result in a much shorter protein than the original gene product?
A frameshift mutation, such as an insertion or deletion of nucleotides, can cause a shift in the reading frame of a gene during translation, leading to a premature stop codon. This results in a truncated protein that is much shorter than the original gene product.
A mutation changes a gene in a cell in the stomach of an organism This mutation could cause a change in?
This mutation could cause a change in the protein produced by the gene, potentially leading to altered cell function or structure in the stomach. It could also impact the organism's digestion process or increase the risk of developing certain diseases related to the stomach.
What is the main question to ask when considering the effect of a mutation?
The main question to consider when evaluating the effect of a mutation is how it alters the organism's phenotype or function. This involves assessing whether the mutation impacts protein structure or function, gene regulation, or any other biological processes that could affect the organism.
Could a mutation affect phenotype?
Yes, a mutation can occur without affecting the phenotype at all. For example, a point mutation may change a nucleotide in a codon, but sometimes, the codon can still code the same amino acid, so the mRNA strand can still make the same protein.
How does a mutation in a sex cell differ from a mutation in a non-sex cell?
Mutations in sex cells can be passed on to children. Mutations in sex cells only affect offspring. Mutations in sex cells do not affect the organism.
Why does mrna mutation affect the amino acid sequence?
The codon UGU codes for the amino acid Cysteine. The codon UGG codes for the amino acid Tryptophan. Therefore the mutation will cause the amino acid Cysteine to be replaced with Tryptophan. These amino acids are quite different, and the final shape of the protein could be changed as a result. This could affect the function of the protein.
What could be described as a chromosomal mutation?
Chromosomal mutation can have lasting impacts on the person who this happens to. A version of a chromosomal mutation is the mutation that leads to Down's Syndrome.
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.
