UNIT 4 concept 1 flashcard

Front

What are the components of a DNA nucleotide?

Back

A DNA nucleotide consists of deoxyribose sugar, a phosphate group, and a nitrogenous base (adenine, guanine, cytosine, or thymine).

Front

What sugar is found in RNA?

Back

The sugar found in RNA is ribose.

Front

What sugar is found in DNA?

Back

The sugar found in DNA is deoxyribose.

Front

What type of bonds connect the base pairs in DNA?

Back

Weak hydrogen bonds connect the base pairs in DNA.

Front

What is the structure of DNA?

Back

The structure of DNA is a double helix.

Front

What is the role of deoxyribose in DNA?

Back

Deoxyribose is the sugar component of DNA nucleotides, providing structural support.

Front

What is the role of ribose in RNA?

Back

Ribose is the sugar component of RNA nucleotides, providing structural support.

Front

What are nitrogenous bases?

Back

Nitrogenous bases are the components of nucleotides that form the genetic code; they include adenine, thymine, cytosine, and guanine.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.

Front

What is a polypeptide?

Back

A polypeptide is a chain of amino acids linked by peptide bonds, forming proteins.
