DNA Vs RNA And Protein Synthesis Updated Answer Key Latest Updated 2023 Rated A+

Q: What type of nucleic acid is single-stranded and contains the bases Guanine, Cytosine, Adenine, and Uracil, and the sugar ribose? A: RNA ________________________________________ Q: What is the role of DNA in controlling the cell and how is it structured? A: DNA’s role is to store genetic information and control cellular functions, and it is structured as a double helix. ________________________________________ Q: In eukaryotic cells, where does DNA replication take place, and when does it occur in the cell cycle? A: DNA replication takes place in the nucleus during the interphase (specifically the S phase) of the cell cycle. ________________________________________ Q: Which type of nucleic acid has the sugar deoxyribose and the base Thymine? A: DNA ________________________________________ Q: What are the roles of helicase, primase, DNA polymerase, and ligase during DNA replication? A: Helicase unwinds the double helix by breaking hydrogen bonds, primase creates an RNA primer, DNA polymerase replicates the DNA molecules to build a new strand, and ligase connects DNA fragments together. ________________________________________ Q: Which type of RNA travels out of the nucleus to a ribosome in eukaryotic cells? A: Messenger RNA (mRNA)
