Flashcards for Gene Expression at the Molecular Level

Transcription

The process that produces mRNA from DNA.

Gene Expression

The processes of transcription and translation combined.

RNA Polymerase

Enzyme used during transcription.

Ribosomes

The location where translation occurs.

Gene

Organized unit of DNA sequences that enables a segment of DNA to be transcribed into RNA and ultimately results in the formation of a functional product.

Transcribed Region

Region of a structural gene that contains the information that specifies an amino acid sequence.

Promoter

The region of the gene where RNA polymerase binds during transcription.

Cap

Added to the 5' end of pre-mRNA in eukaryotes.

Splicing

Process that removes introns from pre-mRNA.

Spliceosome

Complex responsible for removing introns and joining exons in eukaryotic mRNA.

Ribosome

The location of translation.

Peptide Bond

The type of bond that forms between amino acids during translation.
