Document Summary
Dna in the cell is always associated with proteins. Prokaryotes have circular chromosome and smaller circular plasmids. Because dna stores your genetic information and is faithfully replicated, information is passed largely unaltered from cell to cell, generation to generation. Dna is condensed into visible chromosomes only for a brief period in life of a cell. Denaturation is when you separate 2 strands of dna. Dna strands with similar sequences will form partial duplexes or hybrids with each other. This is used to find similarities in different species. Fish: process that vividly paints chromosomes with fluorescent dna probes to identify chromosomal abnormalities. This also aids in gene mapping, and toxicological studies. Determine if you have normal chromosomes or chromosomal abnormalities. From birth to rebirth, a cell progresses through characteristic stages that constitute the cell cycle. Caner is one outcome of a runaway cell cycle. Cell spends most of its time in interphase. Allows creation of unique individuals through sexual reproduction.
