Replication, Transcription and Translation

Front

What is the process to go from mRNA to a protein called?

Back

Translation

Front

Where does transcription take place in a cell?

Back

Nucleus

Front

What enzyme unzips the DNA to prepare for replication?

Back

Helicase

Front

What determines the code of a DNA molecule?

Back

The order (sequence) of the nitrogen bases.

Front

What is a triplet of mRNA called?

Back

Codon

Front

What is the role of RNA polymerase in transcription?

Back

RNA polymerase synthesizes RNA from the DNA template.

Front

What are the three main types of RNA involved in protein synthesis?

Back

mRNA (messenger RNA), tRNA (transfer RNA), rRNA (ribosomal RNA).

Front

What is the function of tRNA during translation?

Back

tRNA carries amino acids to the ribosome and matches them to the codons on mRNA.

Front

What is the significance of the start codon in translation?

Back

The start codon (AUG) signals the beginning of protein synthesis.

Front

What is the difference between replication and transcription?

Back

Replication copies the entire DNA molecule, while transcription copies a specific gene into mRNA.
