BIOL 112 Final Exam Learning Goals (Starts at mutations) 100% Pass 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 am...

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...

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 young patient (5yrs) presents for the first time to a new dentist with crowded teeth, making them very hard to clean. In further exploration of the issue, she learns that the child had delayed eruption of his teeth. The patient's mother also relays that her pediatrician has several times noted how prominent the veins of his scalp are and his short stature. However, she thinks that this is just part of the spectrum seen in their family given that she herself is quite short and has fair ski...
