Bio 104 questions
final
| Question | Answer |
|---|---|
| what would happen if the Hardy-Weinberg equilibrium is met? | allele frequency would remain the same and cause no evolution |
| How do you get transcription? | transcription factors then RNA polymerase |
| What are the changes happening to cells undergoing apoptosis? | cut DNA, become smaller, and flip membrane |
| What are factors being evaluated before a cell is allowed to begin G1 and proceed past the G1 checkpoint? | signal to divide, size, DNA integrity, and proper nutrients |
| chromosomal alterations include: | deletion, translocation, inversion, and duplication |
| sequence of events in translation | initiation, elongation, and termination |
| during replication of DNA, DNA polymerase... | needs a primer to begin |
| correct order of enzymes as they function during DNA replication in eukaryotic cells | begin with helicase, RNA polymerase, then DNA can attach and then add onto the primer |
| what is the result of a cell not meeting the criteria to pass a checkpoint | there is one chance to fix itself and if not, apoptosis occurs |
| what leads to variation of genetic materials | mutations, crossing over, random assortment, and fertilization |
| what is the importance of crossing over | genetic variation |
| evolutionary speaking, why do asexual species have a disadvantage over sexually reproducing species? | less chance of variety |
| can genetic disorders be caused by mutations in introns? | introns are important in regulation and if there are mutations, they cause problems |
| how an allele becomes the most common allele in a population? | because it is preferred in that environment |
| Why was it useful to Darwin to learn that respected geologists thought the earth was very old? | there was enough time for evolution to occur/show |
