Use the information gathered in the nucleotides molecular structure tutorial to answer the question. select the phrases that accurately describe properties of the most common form of the dna double helix. the nitrogenous bases are exposed to the solvent, whereas the sugar–phosphate backbone of each nucleotide strand is in the interior of the double helix. the phosphodiester bonds between nucleotide residues run in opposite directions in the two strands. base pairs have a spacing of 20 å. dna contains equal amounts of adenine and thymine, and equal amounts of cytosine and guanine. a helical turn consists of about 10 base pairs.

6. in domesticated cats, the following are independently assorting: normal ears (t) is dominant to tufted ears (t); curved whiskers (c) is dominant to straight whiskers (c); the presence of six toes (s) is dominant to five toes (s); gene for hair length is an x-linked codominant. the three phenotypes for hair length are long (xhxh), medium (xhxh), and short (xhxh); medium is the heterozygous condition. given two parents: ttccssxhxh x ttccssxhy how many different gametes could be formed in the female cat with respect to these four traits? how many phenotypes are possible in the offspring from this mating?

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.
