What would a single change in the sequence of nitrogenous bases in a DNA molecule most likely result in?
A mutation
A change in which part of a gene is the result of a mutation?
Base Sequence
What is a A genetic mutation that does not result in a change in the amino acid sequence of the resulting protein is called?
a silent mutation.
DNA can result in dysfunctional protein production?
yes but it would most likely be unnoticable
How does a mutation in a gene affect the order of DNA based?
A mutation in a gene can happen by addition, deletion or substitution of base pairs. This means that the order of the bases will change- a new base may be added, a base may be lost, or one base may be substituted for another. The result of these mutations is that it causes the DNA to code for a different protein. If a mutation occurs in a sex cell, the mutation can be passed on to an offspring and affect the offspring's phenotype.
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.
Explain how mutations in gametes may result in phenotypic changes in offspring?
mutation in the DNA will cause the amino acids to code for a different protein, creating a new structure, therefore altering the phenotype.
What would a single change in the sequence of nitrogenous bases in a DNA molecule most likely result in?
A mutation
What kinds of phenotype change are the result of evolution?
Changes that are genetic
When when a mutation results in no significant change in the production of a of a functional protein?
When a mutation does not change the result of a normal production of a protein is called harmless. This is because it does no harm to the individual.
A certain mutant bacterial cell cannot produce substance x. the mutation was most likely the result of a change in the?
gene that codes for a specific protein
Which molecular events result in an irreversible change in genes?
