The domestic cat genome contains 2.9×109 base pairs. the length of linker dna in mammals is 50 base pairs. approximately how many nucleosomes are required to organize the 10-nm-fiber structure of the genome?

You have just sequenced a new protein found in mice and observe that sulfur-containing cysteine residues occur at regular intervals. what is the significance of this finding? it will be important to include cysteine in the diet of the mice. cysteine residues are required for the formation of α helices and β pleated sheets. cysteine residues are involved in disulfide bridges that form tertiary structure. cysteine causes bends, or angles, to occur in the tertiary structure of proteins.
