What is the Central Dogma of Biology?

Back

The Central Dogma of Biology describes the flow of genetic information from DNA to RNA to protein, outlining the processes of transcription and translation.

Front

Where does transcription occur in the cell?

Back

Transcription occurs in the nucleus.

Front

What is the role of ribosomal RNA (rRNA) in translation?

Back

Ribosomal RNA (rRNA) serves as the workbench for translation, providing a site for mRNA and tRNA to interact.

Front

Which enzyme unwinds the DNA double helix during replication?

Back

Helicase unwinds and opens the double helix during DNA replication.

Front

What are codons?

Back

Codons are sequences of three nucleotides in mRNA that correspond to specific amino acids during protein synthesis.

Front

What is the function of DNA replication?

Back

The function of DNA replication is to make a copy of the DNA molecule.

Front

What is the role of messenger RNA (mRNA)?

Back

Messenger RNA (mRNA) carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is the function of transfer RNA (tRNA)?

Back

Transfer RNA (tRNA) transports specific amino acids to the ribosome during protein synthesis.

Front

What are the three main stages of protein synthesis?

Back

The three main stages of protein synthesis are transcription, translation, and post-translational modification.

Front

What is the significance of 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 sequence of amino acids in proteins.
