Which of the following occurs as a ribosome translocates along a mrna molecule by one codon? a. the polypeptide enters the e siteb. the trna that was in the a site moves into the p site. c. the trna that was in the a site moves to the e site and is released. d. the trna that was in the a site departs from the ribosome via a tunnel. e. the trna that was in the p site moves into the a site.

The correct answer is option B. "The tRNA that was in the A site moves into the P site".

Explanation:

In the ribosome complex for translation, the A-site (aminoacyl) acts as the point of entry for the tRNA, and the location at which the first amino acid is bound. Once the first codon has been translated into the first amino acid, The tRNA that was in the A site moves into the P-site (peptidyl). The P-site is the second binding site for the tRNA, and the location at which all the following amino acids are added.

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
