A mutation that does not cause a disease but that is unstable at mitosis and meiosis and can change into a pathogenic mutation. post-zygotic (somatic) mutation missense mutation dynamic mutation premutation correct answers premutation A pathogenic mutation that is unstable at mitosis and meisis result in progressively severe phenotypes becayse oligonucleotides repeat in length and can increase from one generation to the next. post-zygotic (somatic) mutation missense mutation dynami...

The spectrum of p53 mutations is not a strong argument to infer neomorphic or antimorphic mutations Unlike most other tumour suppressor genes that are inactivated by frameshift or nonsense mutations leading to disappearance or aberrant synthesis of the gene product, almost 80% of p53 gene mutations are missense mutations leading to the synthesis of a stable protein, lacking its specific DNA-binding activity and accumulating in the nucleus of tumour cells (Soussi, 2005). Whether this hig...

Identify the different types of point (base substitution) mutations; missense, nonsense and silent mutations. POINT MUTATION: = A change in a single nucleotide Types: 1) Silent Mutation = When the redundancy of the genetic code kicks in and the change in that single nucleotide results in the same amino acid produced as the original code. 2) Missence Mutation = When the change in a single amino acid changes the amino acid produced 3) Nonsense Mutation = When the change in a single nucl...

which to mechanisms both contribute to genetic diversity Correct Answer-meisosis crossing over You have decided to spend money to have all of your potential breeders tested for the presence of a lethal allele. You then breed only those who tested negative. This is an example of: Correct Answer-marker assisted selection The mating of an individual with a dominant phenotype to one that is a known homozygous recessive id termed as: Correct Answer-testcross ______ mating is the mating amo...

Methylases - Answer adds methyl group to restriction sites on cell's own DNA (blocks cleavage) Silent mutation - Answer No change in amino acid sequence Nonsense mutation - Answer Introduction of stop codon Missense mutation - Answer Amino acid change at position Dispersive replication - Answer fragments of original DNA molecules are used as templates Reciprocal translocation - Answer exchange of one part of a chromosome for another (problems in meiosis) Re...
