DNA Flashcard

Front

In which phase does the DNA copy itself?

Back

Interphase is the phase where DNA replication occurs, allowing the cell to prepare for division.

Front

What is the 'backbone' of the DNA strand made of?

Back

The backbone of the DNA strand is made of phosphate and sugar.

Front

What is the process called in which DNA makes an exact copy of itself?

Back

Replication is the process by which DNA makes an exact copy of itself.

Front

What determines the code of a DNA molecule?

Back

The order (sequence) of the nitrogen bases determines the code or information of a DNA molecule.

Front

In which phase do the chromatids split apart?

Back

Chromatids split apart during Anaphase.

Front

What are the building blocks of DNA?

Back

The building blocks of DNA are nucleotides, which consist of a phosphate group, a sugar, and a nitrogenous base.

Front

What are the four nitrogen bases in DNA?

Back

The four nitrogen bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G).

Front

What is the base pairing rule in DNA?

Back

The base pairing rule states that adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is the enzyme responsible for adding nucleotides to the growing DNA strand during replication.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil instead of thymine.
