Complete hydrolysis of a hexapeptide gives 2 gly, leu, phe, pro, and tyr. reaction of the peptide with phenylisothiocyanate gave the phenylthiohydantoin of pro. partial hydrolysis of the peptide gave the following fragments: phe-gly-tyr, gly-phe-gly, pro-leu-gly, leu-gly-phe. what is the structure of the peptide?

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

the answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set
