16. DNA Stands For...Deoxyribonucleic acidDNA is the blueprint of life, containing the genetic instructions for building and maintaining an organism. It is a complex molecule composed of two long chains of nucleotides that are twisted into a double helix shape.17. The Nitrogenous Base Found in RNA But Not in DNA Is...Uracil (U)Uracil replaces thymine (T) in RNA. Both are pyrimidines, a class of nitrogenous bases characterized by a single-ring structure.18. The Process of Making an RNA Copy from DNA is Called...TranscriptionTranscription is the first step in gene expression, where the genetic information encoded in DNA is transferred to RNA. This process is catalyzed by the enzyme RNA polymerase.19. The Sugar Found in RNA is Called...RiboseRibose is a five-carbon sugar that forms the backbone of RNA molecules. In contrast, DNA contains deoxyribose, which lacks an oxygen atom on the second carbon.20. In DNA, Adenine (A) Always Pairs with...Thymine (T)Adenine and thymine form a complementary base pair in DNA through two hydrogen bonds. This pairing is crucial for maintaining the double helix structure and ensuring accurate replication.21. The Shape of DNA is Described as a...Double HelixThe double helix structure of DNA is a defining characteristic, resembling a twisted ladder. The two strands are held together by hydrogen bonds between complementary bases.22. In RNA, Adenine Pairs with...Uracil (U)In RNA, adenine forms a base pair with uracil, which replaces thymine. This pairing is essential for RNA's diverse functions, including protein synthesis.23. The Three Types of RNA Involved in Protein Synthesis Are...Messenger RNA (mRNA): Carries genetic information from DNA to ribosomes, where proteins are synthesized.Transfer RNA (tRNA): Transports specific amino acids to the ribosome, matching them to the mRNA codons.Ribosomal RNA (rRNA): Forms part of the ribosome structure, providing a platform for mRNA and tRNA to interact during protein synthesis.24. The Building Blocks of DNA and RNA Are Called...Nucleotides25. The Process of Assembling a Protein from mRNA at the Ribosome is Called...TranslationTranslation is the second step in gene expression, where the genetic code carried by mRNA is decoded into a specific amino acid sequence, forming a protein.26. The Enzyme Responsible for Unzipping the DNA Double Helix During Replication is...HelicaseHelicase is an enzyme that unwinds the DNA double helix, separating the two strands to allow for replication. This process is essential for creating two identical DNA molecules from one.
