FLASHCARD QUESTION

Front

What is the structure of DNA?

Back

DNA is structured as a double helix, consisting of two strands that wind around each other.

2.

FLASHCARD QUESTION

Front

What are the building blocks of DNA?

Back

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

FLASHCARD QUESTION

Front

What are the four nitrogenous bases in DNA?

Back

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

4.

FLASHCARD QUESTION

Front

How do nitrogenous bases pair in DNA?

Back

Adenine pairs with thymine (A-T) and cytosine pairs with guanine (C-G).

5.

FLASHCARD QUESTION

Front

What is Chargaff's Rule?

Back

Chargaff's Rule states that in any given sample of DNA, the amount of adenine (A) is equal to thymine (T), and the amount of cytosine (C) is equal to guanine (G).

FLASHCARD QUESTION

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand during DNA replication.

7.

FLASHCARD QUESTION

Front

What is the significance of the anti-parallel structure of DNA?

Back

The anti-parallel structure of DNA allows for the proper base pairing and replication of the DNA strands.
