Which of the following is true of transcription?

ribosomes assemble amino acids to make proteins

none of the above

mrna is made from dna in the nucleus

occurs in the cytoplasm

C

Explanation:

The process in which cells make proteins is called protein synthesis. It actually consists of two processes: transcription and translation. Transcription takes place in the nucleus. It uses DNA as a template to make an RNA molecule. RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. Translation reads the genetic code in mRNA and makes a protein.

We discard answer A, because the process in which ribosomes assemble aminoacids to make proteins is called translation.

We can also discard answer D, as transcriptions occurs in the nucleus.

Answer C is correct, as it's true that mRna is made from DNA in the nucleus during transcription.

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
