In the elongation stage of translation,
a. the codons are read in the 3'-to-5' direction.
b. the polypeptide chain grows from the trp to the met direction.
c. peptidyl transferase activity is catalyzed by a ribosomal protein.
d. rrna plays a passive role.
e. rrna is catalytically active.

The answer is A. Codons are read in the 3'- to - 5'.

Explanation:

Note that translation is a process involving the decoding of ribosomes to a specific amino acid.

Elongation is of the stages of translation, others are initiation and termination.

In elongation, each corresponding amino acid is added to the growing chain. This process continues until the codons are read.

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.
