Question

With very few exceptions, all proteins are encoded by nuclear genes and translated in ___________

A) Ribosomes
B) Mitochondria
C) Golgi apparatus
D) Endoplasmic reticulum

Answer 1

Proteins are encoded by nuclear genes and translated in A) ribosomes in the cytoplasm.

Step-by-step explanation:

The correct answer is A) Ribosomes.

Ribosomes are the cellular structures responsible for protein synthesis. They consist of two subunits made up of proteins and ribosomal RNA.

Ribosomes receive instructions from the nucleus in the form of messenger RNA (mRNA), which is transcribed from DNA. The ribosomes read the code provided by the mRNA and use it to assemble amino acids in the correct order, forming a protein.

Proteins are synthesized on ribosomes in the cytosol, except for a few exceptions such as mitochondrial proteins, which are synthesized in the mitochondria. Therefore, the correct answer is Ribosomes.
