DNA transcription and translation

Front

What is DNA?

Back

DNA (Deoxyribonucleic Acid) is the molecule that carries the genetic instructions for life. It is found in all living organisms, including animals, plants, and bacteria.

What is the role of RNA in protein synthesis?

Back

RNA (Ribonucleic Acid) plays a crucial role in translating the genetic information from DNA into proteins. It acts as a messenger between DNA and ribosomes, where proteins are synthesized.

Front

What are amino acids?

Back

Amino acids are organic compounds that serve as the building blocks of proteins. There are 20 different amino acids that combine in various sequences to form proteins.

What is transcription in the context of DNA?

Back

Transcription is the process by which the information in a segment of DNA is copied into messenger RNA (mRNA). This occurs in the nucleus of eukaryotic cells.

What is translation in the context of protein synthesis?

Back

Translation is the process by which ribosomes read the sequence of mRNA and assemble amino acids into a polypeptide chain, forming a protein.

Front

What sugar is found in RNA?

Back

The sugar found in RNA is ribose.

Front

What is the complementary base pairing rule in DNA?

Back

In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). This is known as complementary base pairing.

Front

How many nucleotides are needed to code for one amino acid?

Back

Three nucleotides are needed to code for one amino acid. This sequence of three nucleotides is called a codon.

Front

What is a codon?

Back

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

What is the function of ribosomes?

Back

Ribosomes are cellular structures that facilitate the translation of mRNA into proteins by linking amino acids together in the order specified by the mRNA.
