What is DNA?

Back

DNA (Deoxyribonucleic Acid) is the molecule that carries the genetic instructions for life. It is composed of two strands that coil around each other to form a double helix.

Front

What is the function of DNA polymerase?

Back

DNA polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides to a growing chain during DNA replication.

Front

What is the role of helicase in DNA replication?

Back

Helicase is an enzyme that unwinds and separates the two strands of DNA, allowing replication to occur.

Front

What are the base pairing rules in DNA?

Back

In DNA, adenine (A) pairs with thymine (T), and guanine (G) pairs with cytosine (C).

What is the significance of Rosalind Franklin's photo 51?

Back

Photo 51 was an X-ray diffraction image that provided critical evidence for the double helix structure of DNA, aiding Watson and Crick in their discovery.

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 is the structure of DNA?

Back

DNA has a double helix structure, consisting of two long strands of nucleotides twisted around each other.

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.

Front

What is transcription in the context of DNA?

Back

Transcription is the process of copying a segment of DNA into RNA, which can then be translated into proteins.

Front

What is translation in the context of DNA?

Back

Translation is the process by which ribosomes synthesize proteins using the information encoded in mRNA.
