Lectures - DNA structure and Chromosomal organization

Friday Jan 30 - Monday Feb 02

We are covering chapter 8 in the textbook: DNA structure and chromosomal organization.
We have been talking about a quick story of how DNA was discovered, the structure of nucleic acids, starting by nucleotides and how they can be put together to form the double stranded DNA and the single stranded RNA.

We started talking about how the large molecules of DNA can be compacted in the space of the nucleus, by wrapping DNA around histone cores to form nucleosomes.

Tomorrow we will finish chapter 8 and start chapter 9.

REMINDER: Exam 2 on Friday. It will include material in chapters 5, 6, and 8.
