Central Dogma of Molecular Biology correct answers 1. DNA Replication: makes DNA copies that are passed down 2. Transcription: produces RNA copy of a gene 3. Translation: produces a polypeptide using the information in mRNA Polypeptide can then become part of a functional protein that contributes to an organisms traits Life Cycle of the Cell correct answers G1-G0-G1-S-G2-Mitosis G1 correct answers Interphase growth period within the cell G0 correct answers Interphase rest period S correct answers Interphase period of DNA replication, contents of chromosomes double G2 correct answers Second phase of interphase growth Molecular Structure of DNA correct answers DNA, also called Deoxyribose nucleic acid, is an anti-parallel double helix composed of nucleotides. Each nucleotide contains a phosphate group, a 5 carbon sugar group, and a nitrogen base (A,G,C,T) Nucleotides are attached together to form two long strands that spiral to create a structure called a double helix. If you think of the double helix structure as a ladder, the phosphate and sugar molecules would be the sides, held together by phosphodiester bonds, while the bases would be the rungs. The bases on one strand pair with the bases on another strand: A pairs with T, and G pairs with C, forming the DNA molecule.
