The human and chimpanzee genomes are 98% identical: a. How many nucleotide positions of the human genome differ from the corresponding positions of the chimp genome? Assume that the human genome is 3200 Mb. b. If the coding fraction (that in exons) of the human genome is 1.5% of the […]

It has been conclusively demonstrated that related cells can differ in their metabolic activities under various conditions.

TO obtain clones that differ in the level of metabolic activity associated with their […]
