Biology Flashcards: DNA, RNA, and Protein Synthesis

Front

Adenine

Back

One of the four nitrogen bases in DNA and RNA; pairs with thymine in DNA and with uracil in RNA.

Front

Thymine

Back

A nitrogen base found only in DNA; pairs with adenine.

Front

Guanine

Back

A nitrogen base found in both DNA and RNA; pairs with cytosine.

Front

Cytosine

Back

A nitrogen base in both DNA and RNA; pairs with guanine.

Front

Uracil

Back

A nitrogen base found only in RNA; pairs with adenine.

Front

Ribose

Back

A sugar found in RNA nucleotides.

Front

Deoxyribose

Back

A sugar found in DNA nucleotides.

Front

Nucleotide

Back

The building block of DNA and RNA; made of a sugar, a phosphate, and a nitrogen base.

Front

DNA (Deoxyribonucleic acid)

Back

The molecule that stores genetic information in cells.

Front

RNA (Ribonucleic acid)

Back

A single-stranded molecule that helps carry out the instructions from DNA to make proteins.
