DNA REVIEW

Front

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 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 is the base pairing rule in DNA?

Back

In DNA, Adenine pairs with Thymine (A-T) and Cytosine pairs with Guanine (C-G).

Front

What is the process of transcription?

Back

Transcription is the process by which the information in a DNA sequence is copied into a complementary RNA sequence.

Front

What is the role of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is translation in protein synthesis?

Back

Translation is the process where ribosomes synthesize proteins using the information carried by mRNA.

Front

What is tRNA and its function?

Back

tRNA (transfer RNA) is responsible for bringing amino acids to the ribosome during protein synthesis, ensuring they are added in the correct order.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or stop signal during protein synthesis.

Front

What is the significance of the double helix structure of DNA?

Back

The double helix structure of DNA allows for the stable storage of genetic information and facilitates replication and transcription.

Front

Who were Watson and Crick?

Back

James Watson and Francis Crick are scientists known for discovering the double helix structure of DNA.
