1. What is the primary function of DNA in cells?
Explanation: DNA contains the genetic information needed for the synthesis of proteins.
Report for correction2. Which molecule carries genetic information from the nucleus to the ribosomes?
Explanation: mRNA carries genetic information from DNA in the nucleus to the ribosomes for protein synthesis.
Report for correction3. What is the building block of proteins?
Explanation: Amino acids are the building blocks of proteins.
Report for correction4. Which organelle is responsible for ATP production in eukaryotic cells?
Explanation: Mitochondria are the organelles responsible for ATP (adenosine triphosphate) production, which is a form of cellular energy.
Report for correction5. What is the function of enzymes in biological reactions?
Explanation: Enzymes act as catalysts and accelerate chemical reactions in biological processes.
Report for correction6. Which biomolecule stores and transmits genetic information?
Explanation: Nucleic acids, such as DNA and RNA, store and transmit genetic information.
Report for correction7. What is the complementary base pair to adenine (A) in DNA?
Explanation: In DNA, adenine (A) pairs with thymine (T) through hydrogen bonding.
Report for correction8. Which molecule is known as the "universal energy currency" of cells?
Explanation: ATP is often referred to as the "universal energy currency" because it carries and provides energy for cellular processes.
Report for correction9. What is the function of the ribosomes in cells?
Explanation: Ribosomes are responsible for protein synthesis in cells.
Report for correction10. Which organelle is responsible for the synthesis of lipids and detoxification of drugs in liver cells?
Explanation: The endoplasmic reticulum (ER) is responsible for lipid synthesis and detoxification of drugs in liver cells.
Report for correction11. What is the monomer of nucleic acids?
Explanation: Nucleotides are the monomers of nucleic acids, consisting of a phosphate group, a sugar, and a nitrogenous base.
Report for correction12. Which molecule is responsible for carrying oxygen in red blood cells?
Explanation: Hemoglobin is the molecule responsible for carrying oxygen in red blood cells.
Report for correction13. What is the primary function of RNA in cells?
Explanation: RNA is primarily involved in protein synthesis, as it carries genetic information from DNA to the ribosomes.
Report for correction14. Which type of RNA carries amino acids to the ribosomes during protein synthesis?
Explanation: tRNA carries amino acids to the ribosomes during protein synthesis.
Report for correction15. What is the function of the Golgi apparatus in cells?
Explanation: The Golgi apparatus modifies and packages proteins and lipids for transport within the cell or secretion outside the cell.
Report for correction16. Which nucleic acid is single-stranded and plays a key role in protein synthesis?
Explanation: mRNA is single-stranded and carries the genetic information necessary for protein synthesis.
Report for correction17. What is the name of the process by which cells break down glucose to produce ATP?
Explanation: Cellular respiration is the process by which cells break down glucose to produce ATP.
Report for correction18. Which organelle is responsible for photosynthesis in plant cells?
Explanation: Chloroplasts are responsible for photosynthesis in plant cells.
Report for correction19. What is the name of the process by which DNA is copied to produce a complementary strand of RNA?
Explanation: Transcription is the process by which DNA is copied to produce a complementary strand of RNA.
Report for correction20. Which biomolecule serves as the main structural component of cell membranes?
Explanation: Lipids, particularly phospholipids, serve as the main structural component of cell membranes.
Report for correction21. What is the function of DNA polymerase in DNA replication?
Explanation: DNA polymerase is an enzyme that synthesizes new DNA strands during DNA replication.
Report for correction22. What is the name of the process by which proteins are synthesized based on the information in mRNA?
Explanation: Translation is the process by which proteins are synthesized based on the information in mRNA.
Report for correction23. What is the function of ribosomal RNA (rRNA) in protein synthesis?
Explanation: rRNA forms the structural components of ribosomes, where protein synthesis occurs.
Report for correction24. Which molecule stores and carries energy in cells, especially during short bursts of intense activity?
Explanation: ATP stores and carries energy in cells, especially during short bursts of intense activity.
Report for correction25. What is the name of the process by which cells divide to form new cells with identical genetic material?
Explanation: Mitosis is the process by which cells divide to form new cells with identical genetic material.
