Nonsense mutation Study guides, Revision notes & Summaries

what can restore a frameshift mutation? - another frameshift, microdeletion, and microinsertion A mutation in a particular gene that results in the premature halting of transcription (and, consequently, protein translation) is a___________ mutation. - nonsense Consider a mutation in which the change is from UAC to UAU. Both codons specify the amino acid tyrosine. Which type of point mutation is this? - Silent mutation A ʺpoint mutationʺ refers to mutations involving - a substitution, dele...

The correct answer is 32. 2x2x2x2x2=32 64 10 5’ AUC GGA ACA 3’ 5' AUA GUA ACA 3' The correct answer is 5' AUC GUA ACA 3' Ile Val Thr 5’ AUG GUA ACA 3’ 5’ AUC GCA ACA 3’ 7 If the original coding sequence is 5’ CGA TAC TTC AGA 3’ and it is mutated to 5' CGA TAT TTC AGA 3', what type of mutation would have taken place? (0/1 Points) Silent Missense The correct answer is silent mutation. The nucleotide sequence changes, but it codes for the same amino ...

DNA replication - correct answer untwisted and zipped by hydrogen bonds being broken between two pairs DNA polymerase - correct answer pairs new bases, aka complementary base pairing (ATCG) Chromosome aberrations occur where? - correct answer occurs among number or structure Explain base pair substitution - correct answer mutation where ATCG base pairing is mixed Missense mutation - correct answer A base-pair substitution that results in a codon that codes for a different a...

ADP + P Glucose NAD Which of the following IS a capability of natural selection? Allows for the fittest individuals to produce more offspring. What does it mean when we say the genetic code is redundant? More than one codon can specify the addition of the same amino acid. What amino acid sequence will be generated, based on...

What are the three things a USMLE question about genetics will ask you to do using a pedigree? (Ans- Recognize a mode of inheritance Predict the recurrence risk of a disease, say in an unborn child Identify an OBLIGATE carrier for disease How do you determine the probability of an unborn child being affected by an AR trait when you know the father is a carrier and the mother has probability X of being a carrier? (Ans- Multiply the odds of the baby being affected IF the mother was a carr...

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...
