Question

MRNA is released from the ________________ into the cytoplasm where the ____________ , the organelle responsible for assembling proteins, are located.

A) centriole, golgi body
B) chloroplast, mitochondria
C) mitochondria, endoplasmic reticulum
D) nucleus, ribosomes

Answer 1

The answer is D) nucleus, ribosomes

Answer 2

Answer: The correct answer for the fill in the blank is D) Nucleus, ribosomes.

In all eukaryotic cells, the process of transcription (formation of mRNA from DNA) takes place in the nucleus. mRNA (messenger RNA) is then transported to cytoplasm where it is translated to form proteins at the site called ribosomes.

Ribosome is a specialised membrane bound organelle that is responsible for assembly of proteins.

Thus, option D) Nucleus, ribosomes is the right answer.
