DNA & RNA

Front

What is the structure of DNA?

Back

DNA is a double helix composed of two strands of nucleotides that are twisted around each other.

Front

What is the primary function of DNA?

Back

The primary function of DNA is to store and transmit genetic information.

Front

What is RNA and how does it differ from DNA?

Back

RNA (Ribonucleic Acid) is single-stranded and contains ribose sugar, while DNA (Deoxyribonucleic Acid) is double-stranded and contains deoxyribose sugar.

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).

Front

What are the four nitrogenous bases in RNA?

Back

The four nitrogenous bases in RNA are Adenine (A), Uracil (U), Cytosine (C), and Guanine (G).

Front

What is transcription in the context of DNA and RNA?

Back

Transcription is the process of copying a segment of DNA into RNA.

Front

What is the role of Uracil in RNA?

Back

Uracil replaces Thymine in RNA and pairs with Adenine during RNA synthesis.

Front

What is the semi-conservative model of DNA replication?

Back

The semi-conservative model states that each new DNA molecule consists of one old strand and one newly synthesized strand.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the cellular machinery that assembles amino acids into proteins based on the sequence of mRNA.

Front

What is the significance of Rosalind Franklin's work?

Back

Rosalind Franklin's X-ray crystallography images provided critical evidence for the double helix structure of DNA.
