Ribosomes are small cellular structures that are the sites of ________________.

• protein synthesis

• DNA decoding

• cellular respiration

• photosynthesis

What is the function of ribosomes in protein synthesis?

• To replicate DNA

• To synthesize lipids

• To synthesize proteins

• To modify proteins

Which part of the cell is the site of translation in protein synthesis?

• Nucleus

• Ribosome

• Endoplasmic reticulum

• Golgi apparatus

What is the role of ribosomes in protein synthesis?

• Copying DNA

• Carrying amino acids

• Synthesizing proteins

• Storing genetic information

What is the main function of ribosomes in a cell?

• Lipid synthesis

• Protein synthesis

Answer explanation

The main function of ribosomes in a cell is protein synthesis. They translate messenger RNA (mRNA) into polypeptide chains, which then fold into functional proteins, essential for various cellular processes.

Why are ribosomes considered the site of protein synthesis in Mia's biology experiment?

• They contain DNA that codes for proteins.

• They are the only cellular structure that contains all types of RNA.

• They facilitate the assembly of amino acids into proteins.

• They modify proteins after synthesis.
