UNIT 4 concept 1 flashcard

Front

What is a nucleotide?

Back

A nucleotide is the basic building block of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What are the components of a DNA nucleotide?

Back

A DNA nucleotide is composed of deoxyribose sugar, a phosphate group, and one of four nitrogenous bases: adenine, thymine, cytosine, or guanine.

Front

What is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil.

Front

What is the role of deoxyribose in DNA?

Back

Deoxyribose is the sugar component of DNA nucleotides, providing the structural framework for the DNA molecule.

Front

What is the function of phosphate groups in nucleic acids?

Back

Phosphate groups link nucleotides together, forming the backbone of the nucleic acid strand.

Front

What are nitrogenous bases?

Back

Nitrogenous bases are the components of nucleotides that encode genetic information; they include adenine, thymine, cytosine, and guanine in DNA.

Front

What is the significance of the base pairing rules in DNA?

Back

Base pairing rules (A with T and C with G) ensure accurate replication and transcription of genetic information.

Front

How does RNA differ from DNA in terms of structure?

Back

RNA is typically single-stranded, while DNA is double-stranded, forming a double helix.

Front

What is the role of RNA in protein synthesis?

Back

RNA serves as a template for translating genetic information into proteins during the process of translation.

Front

What is the function of ribose in RNA?

Back

Ribose is the sugar component of RNA nucleotides, providing the structural framework for RNA molecules.
