Mutations that occur in germ-line cells are?
Somatic mutations occur in somatic body cells. These mutations are passed on to daughter cells during mitosis and to the offspring of those cells in turn, but are not passed on to sexually produced offspring.
Mutations that occur at random are called?
Mutations that occur at random are called spontaneous mutations.
When does point mutation occur?
Bacic Answer:Point mutations occur when a single nucleotode is replaced with another nucleotide tide base. Insertion and come in this category.More Detail Answer:Point mutations occur when a single nucleotide is replaced with another nucleotide tide base. Insertion and come in this category. Error in the process of replication of DNA molecule results in point mutations. Sometimes heat of high level radiation cause the error in DNA replication. There are different effects of point mutations. if this type of mutation occurs in the sequence of DNA molecule or exon, then the protein sequence changes present in the gene. If the mutation occurs in the RNA effecting the codon of gene Sickle cell anemia is cause by the point mutations. Changes occur in the beta hemoglobin. it converts GAC sequence into GUG, Point mutation can be subdivided into three types:1) Nonsense mutations are the ones which code for the same amino acid.2) Misssense mutations occur in the genes which code for different amino acid.3)Silent mutations do not affect the function of the protein and code for different of same amino acid.
Mutations that occur at one single nitrogen base are referred to as?
Mutations that occur at one single nitrogen base are referred to as a point mutation.
What type of mutations do not effect phenotype?
Synonymous mutations. These are mutations that happen in the coding regions of genes that change one nucleotide for another. However, because of redundancy in the genetic code (where one amino acid may be coded for by more than one nucleotide sequence) the amino acid sequence of the protein isn't altered. Mutations that occur in non-coding, non-control regions of the genome also don't affect phenotype. You may also wish to look at Wikipedia's entry on silent mutations.
What is a silent muation?
A silent mutation is a type of genetic mutation that does not result in any change to the amino acid sequence of a protein due to redundancy in the genetic code. These mutations often occur in the third position of a codon and are therefore considered "silent" because they do not affect the resulting protein.
Mutations that occur in germ-line cells are?
Somatic mutations occur in somatic body cells. These mutations are passed on to daughter cells during mitosis and to the offspring of those cells in turn, but are not passed on to sexually produced offspring.
What are the impact of mutations and how mutations can have no impact?
Mutations are usually anomalies in the sequence of a particular strand of DNA. The change is the sequence can be of various kinds and their individual effects vary. Sometimes mutations occur but they are never expressed. In such cases, on the whole, the mutation has had no impact. Changes in a single nucleotide can change the reading frame for protein coding regions and can cause misreading of the genetic code. For example, nonsense mutations caused by the exchange of a nucleotide leading to a stop codon can cause truncation of a protein. On the other hand, we can have silent mutations which show no effect because the nucleotide that has been exchanged does not cause change in amino acid sequence. So this would be an example of a mutation which shows no effect.
Mutations that occur at random are called?
Mutations that occur at random are called spontaneous mutations.
Can a frameshift mutation be a silnt mutation?
A frameshift mutation completely changes the genetic code from the point of the mutation, so the protein made as a result of the mutation would have the incorrect structure and would not function as it should.
What is one way that changes can occur in a DNA sequence?
A radioactive carbon isotope can "convert" ... changing the chemistry of a codon.
Mutations in DNA often occur during replication During which phase of the cell cycle do such mutations occur?
Interphase

What are the types of mutations that can occur during transcription and translation?
During transcription and translation, mutations can primarily be classified into three types: point mutations, insertions, and deletions. Point mutations involve a change in a single nucleotide, which can lead to silent, missense, or nonsense mutations. Insertions and deletions involve the addition or loss of nucleotides, potentially causing frameshifts that alter the reading frame of the genetic code. These mutations can impact protein synthesis, leading to functional changes in the resulting proteins.
What types of mutations occur during dan replication and do they cause genotypic and phenotypic changes in offspring?
During DNA replication, mutations can occur as point mutations (like substitutions), insertions, or deletions. These mutations can lead to changes in the genetic code, potentially resulting in genotypic changes that may also manifest as phenotypic changes in offspring. However, not all mutations affect the phenotype; some may be silent or neutral, while others can lead to beneficial or harmful traits. The overall impact on the offspring depends on the nature of the mutation and its effect on protein function.
What type of mutations do not effect phenotype?
Synonymous mutations. These are mutations that happen in the coding regions of genes that change one nucleotide for another. However, because of redundancy in the genetic code (where one amino acid may be coded for by more than one nucleotide sequence) the amino acid sequence of the protein isn't altered.
