DNA Replication and Protein Synthesis

Front

What are the main components of DNA?

Back

DNA is composed of nucleotides, which include a phosphate group, a sugar (deoxyribose), and nitrogenous bases (adenine, thymine, cytosine, guanine).

Front

What is the role of RNA in protein synthesis?

Back

RNA serves as a messenger that carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is the function of DNA helicase?

Back

DNA helicase is an enzyme that unwinds and unzips the DNA double helix during replication.

Front

What is the process of transcription?

Back

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

Front

What is the role of ribosomes in protein synthesis?

Back

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

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 difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil instead of thymine.

Front

What is the significance of the start codon?

Back

The start codon (AUG) signals the beginning of translation and codes for the amino acid methionine.

Front

What is the role of DNA polymerase?

Back

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

Front

What is the end product of translation?

Back

The end product of translation is a polypeptide chain, which folds into a functional protein.
