Bio Quiz 4

The majority of a eukaryotic cell's life is spent in an "in-between-division" stage referred to as interphase. S phase. static phase. innerphase.

Separation of the chromatids at the end of metaphase leads into the next phase, which is Anaphase Interphase Prophase Telophase

Which of the following are features that distinguish cancer cells from normal cells? Normal cells undergo cytokinesis; cancer cells do not undergo cytokinesis. Normal cells have contact inhibition; cancer cells have no contact inhibition. Normal cells metastasize; cancer cells do not metastasize. Normal cells can divide indefinitely; cancer cells can divide a finite number of times.

Animal cells have "counters" that keep track of how many times a cell has divided. These counters are called centromeres. odometers. telomeres. nuclei.

Errors sometimes occur when DNA duplicates itself. Why might that be a good thing? Most errors are, in fact, good for the organism in which they occur. The rebuilding process proceeds much more quickly when a few errors occur. Errors in DNA replication can never be a good thing. New genes can enter the population and be acted upon by evolution.

What are the two major methods of cellular division in eukaryotic cells? meiosis and cloning fission and cloning meiosis and mitosis mitosis and cloning

During which phase of the cell cycle do the chromosomes align in one plane at the center of the cell? Interphase Prophase Metaphase Anaphase Telophase

During DNA replication, each strand serves as a _____________ for the new ________________ strand proofreader; complementary blueprint; template template; supplementary template; complementary

In most bacteria, the DNA is carried in multiple linear chromosomes. multiple circular chromosomes. a single circular chromosome. a single linear chromosome.

DNA replication occurs during the _____________ of the cell cycle. Gap 2 phase S phase Prophase Gap 1 phase
