B. Cell division stops until p53 binds to DNA and repairs the damage. C. p53 is an example of an oncogene, and its expression causes uncontrolled cell division. D. activation of p53 leads to inhibition of the S-phase cyclin-CDK complex.
DNA Extraction and Spooling
DNA forms very long molecules, much longer than the cell in which it is found. The length of DNA can be calculated by multiplying the distance between bases, 3.4 Ångstroms (Å) (100,000,000 Å = 1 cm), by the number of bases in the chromosome, which typically is 1 to …

The number of DNA molecules per chromatid varies between one and two depending on the time in the cell cycle. d. The number of DNA molecules per chromatid is described by the term ploidy. Thus, diploid cells contain two, tetraploid four, etc. e. Each gene is a DNA molecule, and chromosomes contain many genes, therefore each chromatid contains a ...
