DNA Structure and Protein Synthesis

Front

What is DNA?

Back

DNA (Deoxyribonucleic Acid) is the molecule that carries the genetic instructions for life, composed of two strands forming a double helix.

Front

What are the four nucleotide bases in DNA?

Back

The four nucleotide bases in DNA are adenine (A), thymine (T), guanine (G), and cytosine (C).

Front

What is a hydrogen bond in the context of DNA?

Back

A hydrogen bond is a weak bond that forms between the nitrogenous bases of DNA, holding the two strands of the double helix together.

Front

What is the role of mRNA in protein synthesis?

Back

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

Front

What is transcription in the process of protein synthesis?

Back

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

Front

What is translation in the context of protein synthesis?

Back

Translation is the process where ribosomes read mRNA sequences to assemble amino acids into a polypeptide chain.

Front

What is an amino acid?

Back

An amino acid is a building block of proteins, consisting of a central carbon atom, an amino group, a carboxyl group, and a variable side chain.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that specifies a particular amino acid.

Front

What is the significance of the genetic code?

Back

The genetic code is the set of rules by which information encoded in DNA or mRNA is translated into proteins.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where translation occurs, synthesizing proteins by linking amino acids together.
