Question

The bacterium E. coli, which is a major model system for the study of genes and DNA, has a singular circular chromosome of about 4x106 bp. In contrast, human diploid cells have __1__ chromosomes, of __2__ different types (don’t forget that the X 1 Y!). The total amount of DNA found in a haploid cell such as a sperm or egg is called the organism’s “C-value”; the human C-value is __3__.

Explanation / Answer

1) the human chromosomes have 23 pairs that means 46 chromosomes in them..

2) the two different types are X and Y and are autosomes(Homologous chromosomes) and sex chromosomes(hetrologous chromosomes). .

3) the C- value of human egg or sperm is 3.099351..
