Chromosomes are _______ that reside in the nucleus of the cell. Generally DNA resides in a long strand inside the cell's nucleus but as the cell undergoes division the DNA becomes _________________ and separates into chromosomes.
Homework Answers
Chromosomes are thread-like structures (of histone protein and DNA) that reside in the nucleus of the cell. Generally DNA resides in a long strand inside the cell's nucleus but as the cell undergoes division the DNA becomes duplicated and condensed and separates into chromosomes.
Chromosomes are structures that reside in the nucleus of the cell. Generally, DNA resides in a long strand inside the cell's nucleus, but as the cell undergoes division, the DNA becomes condensed and tightly coiled and separates into chromosomes.

Long molecules of DNA can fit into the tiny nucleus because within each chromosome the DNA is packed into an elaborate, multilevel system of coiling and folding. Sexual reproduction may enhance fitness by producing offspring of varied genetic makeup, speeding adaptation to a changing environment. Cancer cells do not respond normally to the specialized proteins that control the cell cycle; they divide excessively and may invade other tissues of the body. During cell division, each daughter cell receives one identical...

Telomeres are long stretches of non-coding DNA at the ends of linear (eukaryotic chromosomes. A beneficial effect of having telomeres is that they -7 speed up the rate of cell proliferation. B)prevent shortening of the leading strand of the DNA during replication prevent shortening of the lagging strand of the DNA during replication D. eliminate the need for RNA primers during DNA replication E. help to splice out introns

In order to fit inside the nucleus of a cell eukaryotic DNA needs to be compacted sinificantly (A) Discuss the role of histones in the compaction of eukaryotic DNA. Make sure you first define what histones are before describing how they aid in compaction. Also discuss how the enzyme Nase I was used to determine the structure of nucleosomes (B) What are radial loops, and how do they further aid in DNA Compaction! Be sure to state how the loops...

Which among A-D is false regarding most DNA virus infections and most non-retroviral RNA virus infections? A. Once inside the host cell, RNA virus replication usually (though not always) occurs completely in the cytoplasm. B. The genome of DNA viruses generally must enter the nucleus of the host cell they infect. C. A (+) sense RNA strand produced by an RNA virus could serve as an mRNA and be directly translated into protein. D. DNA viruses typically are assembled in...
