What is it called when replication is messed up?
Mutation occurs, if a mutation is recessive it is not expressed in the phenotype, if however it is dominant when passed on in the offspring it is expressed in the phenotype.
Which gene mutation is less likely to result in a phenotype change and why?
phylogeny
What is a backmutation?
A backmutation is a mutation in genetics which restores the original sequence and the original phenotype.
Which genotype will give rise to the Bombay phenotype?
The Bombay phenotype is caused by a homozygous recessive mutation in the FUT1 gene, which results in the absence of H antigen on red blood cells. Therefore, the genotype for the Bombay phenotype is hh.
Mutations in introns are less likely to affect phenotype then mutation in exons?
Mutations in introns are less likely to affect phenotype because introns are not translated into protein, unlike exons which contain coding regions for proteins. Introns are involved in regulation of gene expression through processes such as alternative splicing, but mutations within introns typically have a more subtle impact on gene expression compared to mutations in coding regions (exons).
What is it called when replication is messed up?
Mutation occurs, if a mutation is recessive it is not expressed in the phenotype, if however it is dominant when passed on in the offspring it is expressed in the phenotype.
Is a mutation deleterious?
A deleterious mutation has a negative effect on the phenotype, and thus decreases the fitness of the organism. (A harmful mutation)
Which gene mutation is less likely to result in a phenotype change and why?
phylogeny
What cell mutation does not impact the phenotype of the organism because the protein remains unchanged?
It is possible for a point mutation to not change the sequence of amino acids in a protein. This will result in the protein being unchanged and will not affect the phenotype.
Describe 4 ways mutation can occur without change its phenotype?
The phenotype will not be affected with silent mutation and synonymous mutation. It also can be mutated in a coding region that changes the amino acid or changes the protein to be folded.
What is a backmutation?
A backmutation is a mutation in genetics which restores the original sequence and the original phenotype.
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.
A mutation in a gene may not affect an individual's phenotype because?
the mutation may occur in a non-coding region of the gene, resulting in no change to the protein produced. Additionally, the mutation may be silent, meaning it does not alter the amino acid sequence of the protein. In some cases, the organism may have redundant genes that compensate for the mutation, allowing it to function normally.
What is a phenotype that can cause major or minor health problems and is related to an inherited mutation in a gene?
gene
What is it called when DNA replication messes up?
When DNA replication makes a mistake, it is called a mutation. Mutations can lead to changes in the genetic code that may affect the function of the protein encoded by that DNA sequence.
Which genotype will give rise to the Bombay phenotype?
The Bombay phenotype is caused by a homozygous recessive mutation in the FUT1 gene, which results in the absence of H antigen on red blood cells. Therefore, the genotype for the Bombay phenotype is hh.
What is phenotype that can cause major or minor health problems and is related to an inherited mutation in a gene called?
