DNA Structure & Replication Test

Front

What is the 'Base-Pair' rule in DNA?

Back

The 'Base-Pair' rule states that in DNA, adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G).

Front

What enzyme is responsible for unzipping DNA during replication?

Back

DNA Helicase is the enzyme that breaks the hydrogen bonds between the base pairs, unzipping the DNA strands.

Front

Who discovered the double helix structure of DNA?

Back

James Watson and Francis Crick are credited with the discovery of the double helix structure of DNA.

Front

What technique did Rosalind Franklin use to study DNA?

Back

Rosalind Franklin used X-ray diffraction to produce images of DNA molecules, contributing to the understanding of its structure.

Front

What does it mean that the genetic code is universal?

Back

The genetic code is universal because a DNA sequence can code for the same proteins across different species.

Front

What are nucleotides?

Back

Nucleotides are the building blocks of DNA and RNA, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What role does DNA Polymerase play in DNA replication?

Back

DNA Polymerase is the enzyme that synthesizes new DNA strands by adding nucleotides complementary to the template strand.

Front

What is the function of DNA telomerase?

Back

DNA telomerase extends the telomeres of chromosomes, helping to maintain their length during replication.

Front

What is the significance of complementary base pairing?

Back

Complementary base pairing ensures accurate DNA replication and transcription, as each base pairs specifically with its partner.

Front

What is the structure of DNA?

Back

DNA has a double helix structure, consisting of two strands that wind around each other, with sugar-phosphate backbones and nitrogenous bases in the center.
