Study Guide Chromosome Structure & Transposable Elements After these lectures you should be able to Answer the following questions from your textbook: o Chapter 11 2, 4, 8, 10 , 12, 19, 24, 27, 35, 37, 39 Compare and contrast prokaryotic and eukaryotic DNA packing mechanisms Describe the various levels of DNA packaging seen in eukaryotic chromosomes Describe the essential elements of eukaryotic chromosomes Distinguish between heterochromatin and euchromatin Compare and contrast the types of DNA sequences in eukaryotes (unique, highly repetitive, moderately repetitive) Identify any repetitive sequences that are functional. Describe the types of Highly repetitive DNAs -differentiate between satellite DNA and smaller mini and microsatellites Describe why the P element in drosophila is a genetic sexual disease.

Unformatted text preview: Describe how DNA transposons move compared to retrotransposons Describe what transposable elements are in the human genome What is the difference between a LINE or SINE retroelement? What is a retroelement? How does it move? WORD LIST centromere HU protein- bacteria Satellite DNA-highly repetitive near centromeres DNA transposon IS element SINE e.g. AluI element ERV-endogenous retrovirus LINE Supercoiling of DNA euchromatin Microsatellite DNA telomerase heterochromatin nucleosome telomere highly repetitive DNA origin of replication Topoisomerase/gyrase histones repetitive DNA transposase Histone tails-acetylation retrotransposon unique sequence DNA Histone H1 reverse transcriptase 30nm fiber...
