DNA, RNA & Protein Synthesis 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 is RNA?

Back

RNA (Ribonucleic Acid) is a single-stranded molecule that plays a crucial role in the synthesis of proteins by carrying the genetic information from DNA.

Front

What is the function of mRNA?

Back

mRNA (messenger RNA) serves as a template for protein synthesis by conveying genetic information from DNA to the ribosome.

Front

What is transcription?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically mRNA, which then carries the genetic information to the ribosome.

Front

Where does transcription occur in eukaryotic cells?

Back

Transcription occurs in the nucleus of eukaryotic cells.

Front

What is translation?

Back

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

Front

What are ribosomes?

Back

Ribosomes are cellular structures that facilitate the translation of mRNA into proteins.

Front

What is the role of tRNA?

Back

tRNA (transfer RNA) is responsible for bringing the appropriate amino acids to the ribosome during protein synthesis.

Front

What is the genetic code?

Back

The genetic code is a set of rules that defines how the sequence of nucleotides in DNA and RNA is translated into the amino acid sequence of proteins.

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.
