Document Summary
He201 lesson 27 function of z-dna in living cells. In which parts of the genome might you expect to find at- rich sequences: 13 the human genome has a gc content of 40. 3%. In other words, 40. 3% of the nucleotides in the genome are either g or c. the gc contents for different organisms vary over a wide range. The genome of the malaria parasite, plasmodium falciparium, has a gc content of just 19. 0%, whereas that of the bacterium streptomyces griseolus is. Speculate on the reasons why the gc contents for different species should be so different. A gene is a segment of a dna molecule. The shortest genes are less than 100 bp in length, and the longest ones are over 2,400,000 bp. The biological information that they contain is split into sections called exons, separated by intervening sequences called introns. Protein synthesis is the key to expression of biological information. Proteins of different types have many different functions.
