Module 5C Homework Name ______________________ 10 points total
We’ve got some homework. I’ve taken problems from chapter 9. Some of them require you to go to the website for the National Center for Biotechnology Information. If you become a geneticist, a biochemist or a molecular biologist, you’ll go to this website often.
I recommend that you read the Chapter questions on page 213. They are easy, and provide the answers..
Genomics on the web at http://www.ncbi.nlm.nih.gov. Go to that website and bookmark it. Do these problems, found on page 216 of Snustead and Simmons. At the NCBI website, in the search bar type in Genome data Viewer. In the search bar for organisms, Search Homo sapiens. Scroll to the bottom of the page. You will see ideograms (illustrations) of chromosomes on the bottom right. Click on the largest chromosome to answer #1, and the smallest to answer #2. Use the search function to answer #3.
The available evidence indicates that each eukaryotic chromosome contains one giant DNA molecule.
- Which human chromosome contains the largest DNA molecule? How large is it in base pairs (the answer is at the top of the screen beside the name of the chromosome)? (2 pts) ___
- Which human chromosome contains the smallest DNA molecule? How many base pairs does it contain? (2 pts) ___
- Which human chromosomes contain genes encoding H1 histones? Just select the ones that have H1 in the title. (use the Search bar on the left nav panel, type in histone H1) (3 pts) ___
- What was the objective of the experiment carried out by Hersey and Chase? How was it accomplished, and what was the significance of the experiment? (2 pts) ___
- Are the scaffolds of eukaryotic chromosomes composed of histone or nonhistone chromosomal proteins? (1 pt) ___
