DNA Structure and Replication

Front

What is the basic structure of DNA?

Back

double helix

Front

If a DNA strand has 35% A, what percent T would be present?

Back

35%

Front

Which 2 molecules form the sides (backbone) of the DNA ladder?

Back

deoxyribose sugar and phosphate

Front

What is meant by semi-conservative replication?

Back

Each new DNA molecule consists of one original strand and one newly synthesized strand.

Front

What was Rosalind Franklin's contribution to the discovery of DNA?

Back

She took the first X-Ray image of DNA.

Front

What are the four nitrogenous bases in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), Guanine (G).

Front

What is the role of DNA polymerase in DNA replication?

Back

DNA polymerase synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the function of the phosphate group in DNA?

Back

The phosphate group forms part of the backbone of the DNA structure, linking deoxyribose sugars.

Front

What is the significance of complementary base pairing in DNA?

Back

Complementary base pairing ensures accurate replication and transcription of genetic information.

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.
