Ribosomes and Protein Synthesis Quiz

What is the structure of ribosomes?

• Single subunit made up of DNA and proteins

• Two subunits made up of ribosomal RNA (rRNA) and proteins

• Three subunits made up of ribosomal DNA (rDNA) and lipids

• No specific structure, just a collection of proteins

What is the structure of ribosomes?

• Ribosomes are composed of two subunits, one large and one small, made up of ribosomal RNA (rRNA) and proteins.

• Ribosomes are composed of a single subunit made up of phospholipids and carbohydrates.

• Ribosomes are composed of three subunits, two large and one small, made up of DNA and lipids.

• Ribosomes are composed of one subunit made up of carbohydrates and amino acids.

What is the primary role of mitochondria?

• DNA replication

• Energy production

• Protein synthesis

• Cell division

What is the primary function of ribosomes in protein synthesis?

• Ribosomes break down proteins into amino acids

• Ribosomes assemble amino acids into proteins according to the instructions from mRNA.

• Ribosomes transport proteins to different parts of the cell

• Ribosomes store amino acids for future use

What is the process of protein synthesis?

• Replication and recombination

• Transcription and translation

• Mitosis and meiosis

• Photosynthesis and respiration

What is the first step in protein synthesis?

• Formation of DNA, mRNA, and initiator tRNA

• Activation of the ribosome, mRNA, and initiator tRNA

• Assembly of the ribosome, mRNA, and initiator tRNA to form the initiation complex.

• Breakdown of the ribosome, mRNA, and initiator tRNA

What is the function of tRNA in protein synthesis?

• tRNA helps in cell division

• tRNA produces energy for the cell

• tRNA carries amino acids to the ribosomes

• tRNA is responsible for maintaining cell structure

What is the role of tRNA in protein synthesis?

• tRNA carries genetic information in the form of nucleotides

• tRNA carries genetic information in the form of amino acids

• tRNA carries genetic information in the form of enzymes

• tRNA carries genetic information in the form of codons

What is the function of mRNA in protein synthesis?

• mRNA breaks down proteins during protein synthesis

• mRNA carries the genetic information from DNA to the ribosome during protein synthesis

• mRNA regulates gene expression during protein synthesis

• mRNA transports amino acids to the ribosome during protein synthesis

How does tRNA contribute to the process of protein synthesis?

• tRNA transports lipids to the ribosomes during protein synthesis.

• tRNA transports nucleic acids to the ribosomes during protein synthesis.

• tRNA transports amino acids to the ribosomes during protein synthesis.

• tRNA transports carbohydrates to the ribosomes during protein synthesis.
