Today we covered pages 195-201 of the book. The chapter starts with DNA structure and function, although we threw in a little bit of RNA structure and function as well. The videos about transcrption and translation didn't work in the presentation I had in class, but I'll post them in this blog shortly.
Next reading: Chromosomes - pages 202-219 and 233-245
Quiz #5 Q&As
1. What are the three main steps of PCR?
Denaturation, annealing, extension (a.k.a. elongation)
2. What are the building blocks of DNA?
Sugar, phosphate group, nitrogenous base
3. What is transcription?
Trnasfer of information from DNA to RNA
4. What is gene duplication?
The copying of a gene and accidental retention of the copy within the genome. The two copies are functional, but one of them may mutate and become a pseudogene and/or eventually become a new functional gene.
5. What is a gene family?
A group of genes that have been generated throufh several gene duplication events, and therefore are similar to eac other in sequence and probably in function.
