What do molecular clocks use to measure evolutionary time?
mutation rates
What will most likely happen to a monkey if mutation occurs in an eye cell?
the monkey will not be strongly affected.
What are Symptoms of the human mutation and effects?
The curious thing about any type of genetic mutation is that it can change anything in any place on the affected chromosome. Most genetic mutations have no affect on the phenotype. In some extreme cases though (i.e. LOTS of radiation) offspring are known to have extensive genetic mutation.
Is marfan syndrome a genetic disease?
Yes, Marfan syndrome is a genetic disorder. It is not a disease. It is caused by a mutation in fibrillin and is an autosomal dominant mutation. This means that if you have a Marfan causing mutation, you have Marfan, and you have a 50/50 chance of passing it on to any children you may have. Severity of Marfan can vary within a family, even though all affected family members have the same mutation. It can not skip generations.
What event will increase the frequency of a mutation in a population over time?
Mutation is the alteration of the nucleotide sequence of an organism, virus, or gene. A mutation can be caused by many factors like radiation and chemical exposure, inadequate nutrition, drastic changes in the environment, or an error in DNA replication. The frequency of occurrence of a particular mutation in the gene pool can be affected by drift, natural selection, sexual selection.
What is the relationship between mutation rates and generation span?
The relationship between mutation rates and generation span is that they both have in impact on the Mitochondrial DNA diversity patterns,unexpected variation of mutation rate across species
Are mutation rates higher in prokaryotes that reproduce by binary fission?
yes
What do molecular clocks use to measure evolutionary time?
mutation rates
If a nucleotide pair were removed from a gene what would be affected?
Every pair in the sequence after that pair would be affected. Probably resulting in a mutation.
What are molecule clocks?
Molecular Clocks- are models that use mutation rates to measure evolutionary time.
What is considered to be the average natural mutation rate that occurs during DNA replication?
It is suggested that mutation rates are on the order of 10 X(neg8) per site per generation.
What will most likely happen to a monkey if mutation occurs in an eye cell?
the monkey will not be strongly affected.
What functions of cells can be affected by a mutation?
because of an error during meiosis or mitosis or because of something in the enviroment.
What rays increases mutation rates?
UV rays. These cause thymine to form dimers in skin cell DNA.
Why are male mutation rates higher than female?
This is because mutations occur in x chromosomes. The male, who has "xy" sex chromosomes, will have the mutation if it is present in the x chromosome. Females, there is a smaller chance because there are two "xx" chromosomes, which reduces the chance that the mutation will be present.
Mutations in body cells can be passed on to offspring of the affected individual?
No. As long as the mutation does not occur in the reproductive cells (sperms or ovum), it will not be pass on to the offspring.
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.
