Detailed explanation-1: -As mentioned above, ribosomes are the molecular machines responsible for protein synthesis. A ribosome is made out of RNA and proteins, and each ribosome consists of two separate RNA-protein complexes, known as the small and large subunits.
Detailed explanation-2: -Ribosomes produce proteins by following instructions that come from DNA.
Detailed explanation-3: -The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm. Translation, the second step in getting from a gene to a protein, takes place in the cytoplasm.
Detailed explanation-4: -The nucleus contains the cell ‘s DNA and directs the synthesis of ribosomes and proteins.
Detailed explanation-5: -Ribosomes. Ribosomes are the protein factories of the cell. Composed of two subunits, they can be found floating freely in the cell’s cytoplasm or embedded within the endoplasmic reticulum.
