Quiz #1: Nucleosides, Nucleotides and Nucleic Acids

• Unbranched polymers composed 

 of repeating monomers called nucleotides

• Nucleosides

• Nucleotides

• Nucleic Acids

• Nucleoprotein

• Compose DNA and RNA consist of:
  a monosaccharide, a N-containing base, and a phosphate group

• Nucleosides

• Nucleotides

• Nucleic Acids

• Nucleoprotein

• Formed by joining the anomeric carbon of the monosaccharide with a N atom of the base.

• Nucleosides

• Nucleotides

• Nucleic Acids

• Nucleoprotein

• Formed by adding a phosphate group to the 5′-OH of a nucleoside.

• Nucleosides

• Nucleotides

• Nucleic Acids

• Nucleoprotein

• A polynucleotide contains a backbone consisting of alternating sugar and phosphate groups.

• Nucleosides

• Nucleotides

• Nucleic Acids

• Nucleoprotein

Two main types of nucleic acids

• DNA and ATP

• DNA and RNA

• RNA and mRNA

• mRNA and tRNA

What is the structure of DNA?

• B-form double helix

• A-form helix or linear

• Z-form single helix

• Triple-stranded helix

What is the structure of RNA?

• B-form double helix

• A-form helix or linear

• Z-form single helix

• Triple-stranded helix

Which of the following are functions of DNA? (Choose all that applies)

• Storage of genetic information (long term)

• Heredity: Transmission of genetic information to make other cells and new organisms

• Protein synthesis: Translates genetic information in DNA, transfer the genetic code from the nucleus to the ribosomes to make proteins

• Genetic Material in Some Viruses
