The function of trna is to
a. transfer amino acids to ribosomes.
b. make mrna.
c. make dna.
d. form ribosomes.

The correct answer is a - transfer amino acids to the ribosomes.

In the nucleus, information to synthesize a particular protein is transcribed from DNA and onto messenger RNA (mRNA).

mRNA leaves the nucleus and enters the cytoplasm of the cell where it attaches to a ribosome.  tRNA then begins to read(translate) the information on the attached mRNA, and corresponding to this information, fetches amino acids from the pool of free amino acids in the cytoplasm and brings them to the ribosome where they get  linked together into a long chain or polymer, forming the primary structure of the protein.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
