Understanding Nucleic Acids

Mr. Anderson explains nucleic acids, focusing on DNA and RNA's roles in protein synthesis and genetic inheritance. He describes nucleotide structures, including phosphate groups, sugars, and nitrogenous bases. The video covers the differences between DNA and RNA, such as their bases and structural forms. It also introduces Eterna, a game for designing RNA sequences.

What is the primary function of DNA and RNA in cells?

• To store energy

• To make proteins

• To provide structural support

• To transport nutrients

What are the building blocks of DNA and RNA?

• Monosaccharides

• Fatty acids

• Nucleotides

• Amino acids

Which component of a nucleotide contains nitrogen?

• Carbon backbone

• Nitrogenous base

• Pento sugar

• Phosphate group

Which nitrogenous base is found in RNA but not in DNA?

• Thymine

• Adenine

• Uracil

• Guanine

What type of bond connects nucleotides in a single strand of RNA?

• Covalent bond

• Hydrogen bond

• Ionic bond

• Metallic bond

What structural feature distinguishes DNA from RNA?

• RNA is found only in the nucleus

• DNA is a double helix

• DNA is a single helix

• RNA contains thymine

Where is DNA primarily located within a cell?

• Cytoplasm

• Ribosome

• Nucleus

• Cell membrane

What is the purpose of the Eterna video game?
