What is the function of RNA in the body?

• Carrying instructions from DNA for controlling protein synthesis

• Producing energy for the cell

• Regulating cell division

• Storing genetic information

What is the difference between DNA and RNA?

• DNA is double-stranded and contains the sugar deoxyribose, while RNA is single-stranded and contains the sugar ribose.

• DNA is single-stranded and contains the sugar ribose, while RNA is double-stranded and contains the sugar deoxyribose.

• DNA and RNA are both double-stranded and contain the sugar deoxyribose.

• DNA and RNA are both single-stranded and contain the sugar ribose.

What are the three main types of RNA?

• DNA, tRNA, rRNA

• mRNA, DNA, rRNA

• mRNA, tRNA, rRNA

• mRNA, tRNA, DNA

What is the role of mRNA in protein synthesis?

• mRNA helps in the production of ATP in the mitochondria

• mRNA is responsible for breaking down proteins in the cell

• mRNA acts as a structural component of the cell membrane

• mRNA carries genetic information from DNA to the ribosomes for protein synthesis

What is tRNA and its function in protein synthesis?

• tRNA is responsible for DNA replication

• tRNA carries lipids to the ribosome

• tRNA functions as a structural component of the ribosome

• Carry amino acids to the ribosome and match them to the mRNA codon sequence during translation

What is rRNA and its role in protein synthesis?

• rRNA functions as a storage molecule for genetic information

• rRNA is responsible for DNA replication

• Ribosomal RNA (rRNA) is involved in forming the structure of ribosomes and in the binding of mRNA and tRNA during translation.

• rRNA is involved in the synthesis of lipids
