These are the topics you should know for the test on Thursday:
Chapter 16:
1) Race to discover DNA structure (Pauling, Watson & Crick, Franklin & Wilkins)
2) Basic structure of nucleotides and double helix, hydrogen bonding, base pairing
3) Be able to describe the replication of DNA, using terminology and names of enzymes correctly
4) Understand that replication has an editing process that corrects most mismatches
5) Know what telomeres are and what happens to them in normal somatic cells as the cell divides
6) Be able to describe the packing of chromatin in chromosomes, including the terms: histones, nucleosomes, "beads on a string"
Chapter 17:
7) Be able to describe the processes of transciption and translation for eukaryotes using the vocabulary we used in class, which includes: messenger RNA, RNA polymerase, 5' cap, poly-A tail, introns, exons, transfer RNA, promoter, initiation, elongation, termination, ribosomes (large subunit and small subunit), aminoacyl-tRNA synthetases, etc.
8) Be able to use the genetic code in both directions: determine amino acid sequence by reading code, write code for a particular amino acid sequence, understand the concepts of codons, anticodons, start signal, stop signals
9) Be able to explain how point mutations and frameshift mutations can affect the production of a polypeptide and ultimately affect an organism's phenotype, know which type of mutation is most likely to affect the polypeptide, including where in the gene the mutation occurs
