You perform a third experiment, in which you add both srp and er membrane vesicles to your protein-synthesizing system, and find that translation of the prolactin mrna now produces a polypeptide 199 amino acids long. what is the explanation of the results? where would you expect to find this polypeptide? drag the terms on the left to the appropriate blanks on the right to complete the sentences. terms can be used once, more than once, or not at all.

See details below...

Explanation:

SRP binds to the ER signal sequence of the newly forming polypeptide chain and halts protein synthesis, thereby preventing the chain from growing beyond 199 amino acids. Upon docking, the nascent peptide chain is inserted into the translocon channel where it enters into the ER. Protein synthesis resumes as SRP is released from the ribosome without this a complete pre prolactin chain might be produced.

i think that the best answer would be c.

tell me if im wrong : )

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
