Guida verificata passo dopo passo1
Identify the function of the ribosome: Ribosomes are cellular structures responsible for synthesizing proteins by translating messenger RNA (mRNA) into a polypeptide chain.
Understand the process of translation: During translation, the ribosome reads the sequence of codons on the mRNA and uses transfer RNA (tRNA) to bring the corresponding amino acids.
Recall the types of biological molecules: Proteins are composed of amino acids, while RNA and DNA are nucleic acids, and lipids are hydrophobic molecules like fats and oils.
Eliminate incorrect options: Ribosomes do not synthesize RNA, DNA, or lipids. RNA is synthesized by RNA polymerase, DNA is replicated by DNA polymerase, and lipids are synthesized in the smooth endoplasmic reticulum.
Conclude that the ribosome synthesizes proteins: Based on the ribosome's role in translation, the correct answer is that it synthesizes proteins.
