Unit 15: Gene Expression

Flashcards covering key concepts from Unit 15: Gene Expression, focusing on transcription processes and RNA types.

The central dogma of molecular biology illustrates the flow of genetic information from to to __.

DNA, RNA, Protein

In prokaryotes, RNA polymerase requires a __ unit for binding to DNA during transcription initiation.

sigma

The __ is a sequence of DNA that forms a recognition and binding site for RNA polymerase.

promoter

In eukaryotic transcription, the __ box is a common element found in RNA polymerase II promoters.

TATA

__ are sequences that are transcribed but not translated, and are removed during mRNA processing.

Introns

The of mRNA is added at the 5' end during processing.

5' cap

__ is a process that involves the removal of introns from pre-mRNA to produce mature mRNA.

Splicing

In eukaryotic cells, the __ participates in the splicing of pre-mRNA by recognizing intron-exon boundaries.

spliceosome

mRNA processing includes the addition of a poly-A tail at the __ end of the mRNA.

3'.

During prokaryotic transcription, the sequence from the promoter to the terminator is referred to as the __ unit.
