proteins are synthesized by ribosomes in all cells

|
proteins are synthesized by ribosomes in plant cells only

|
|
proteins are synthesized by the nucleus in all cells

Detailed explanation-1: -Which is the most accurate statement concerning protein synthesis in cells? Proteins are synthesized at the mitochondria in all living cells.
Detailed explanation-2: -The ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence. Ribosomes use cellular accessory proteins, soluble transfer RNAs, and metabolic energy to accomplish the initiation, elongation, and termination of peptide synthesis.
Detailed explanation-3: -Ribosomes join amino acids to form a polypeptide. Ribosomes have a binding site for mRNA and three binding site for tRNA molecules. No protein synthesis within a cell would occur without ribosomes. All of the above statements are true.
