Which of these is the primary site of protein synthesis? mitochondria cytoplasm nucleus ribosomes

The primary site of protein synthesis is the ribosome.

The ribosome is a small spherical organelle with two subunits that serve as the site for protein synthesis. During the synthesis of protein, mRNA binds to the ribosome and the genetic codes get translated to their respective amino acids and linked together.

More on the functions of the ribosome can be found here: link

A. Ribosome

Explanation:

Ribosome is a sub cellular structure, that is involved in protein synthesis.

Mitochondria is a sub cellular structure, where cellular respiration takes place, therefore it is called the energy house of the cell.

Cytoplasm is a jelly like structure in which sub cellular structures are found.

Nucleus is the main part of the cell in which all cellular activity is controlled by.

It contains DNA and RNA.

Nucleus is mostly known for it's thread like structure that contains hereditary information which is passed from parents to offspring.

Hope it helps ;) ❤❤❤

i think that you are smart and you should fit for it out

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
