To review:
The organisms from Table 1, which has similar GC (cytosine and guanine) and AT (adenine and thymine) contents and the mechanism by which their genetic makeup is similar yet they are different from each other.
Given:
The data of the total content of AT and GC in the tissues of some organisms is compiled in the form of Table 1, below:
Table 1: Total AT and GC content of DNA in some organisms.
Organism and the tissue from which DNA is extracted | A+T | C+G |
Herring sperm | 55.3 | 44.8 |
Rat bone marrow | 57 | 42.9 |
Human sperm | 61.9 | 38.1 |
Escherichia coli | 49.9 | 50.1 |
Yeast | 64.2 | 35.8 |
