Answer:
Explanation:
The ribosomes are small organelles made of RNA and proteins. Its function is the same in both prokaryotic and eukrayotic cells: <u>protein synthesis. </u>
The process begins in the nucleus. The DNA and genetic information is housed here. Certain sections are transcribed and copied to make messenger mRNAs that can fit through the nucleus and pores to travel out to the ribosomes.
The ribosomes use the mRNA in a process called translation. They match each set of 3 nucleotides (a codon) in the mRNA to 1of 20 different amino acids. A special sequence of amino acids forms, the molecule folds, and a protein is formed.
So, a ribosome is the main site for protein synthesis and the correct choice is A.

Useful traits have been accumulated in plants and animals over the centuries by how plants have undergone through certain phases, specifically called selection. Most of these traits are accumulated naturally but others may be acquired in the opposite way through man-made cultivation. Hope this answers your question.
