Additional Problems
When cells of a multi-cellular organism exit either semi-permanently or permanently from the cell cycle and develop a differentiated (specific) function, they are said to be ina. G0b. G1c. G2d. G3
The genome of an organism is all of its: a. Proteinsb. RNAc. Characteristicsd. Genetic materiale. All are correct
Eukaryotic chromosomes become microscopically visible before cell division because:  a. They become less tightly wound b. They become more tightly wound c. They increase in length d. They become more tightly wound and increase in length e. They become less tightly wound and increase in length
One of two identical attached copies of a replicated chromosome defines the term:  a. Centromere b. Chromatin c. Chromosome d. Nucleosome e. Chromatid
A part of a chromosome that attaches sister chromatids to each other defines the term: a. Chromatinb. Nucleosomec. Centromered. Histonee. None of the above are correct
DNA and associated proteins in the nucleus defines the term: a. Centromereb. Nucleosomec. Histoned. Chromatine. Chromosome
A discrete continuous molecule of DNA wrapped around protein defines the term: a. Nucleosomeb. Chromosomec. Centromered. Histonee. Genome 
"Sister chromatids" are: a. Genetically identical and attached to each other at centromereb. Genetically different and attached to each other at centromerec. Genetically differentd. Genetically identicale. Attached to each other at centromere
The correct sequence for the phases of the cell cycle is:  a. Interphase - prophase - prometaphase - metaphase - anaphase - telophase b. Prophase - prometaphase - metaphase - anaphase - telophase c. Prophase - prometaphase - anaphase - metaphase - telophase d. Interphase - prometaphase - prophase - metaphase - anaphase - telophase e. Metaphase - anaphase - interphase - prophase - telophase
