how Genes are Expressed Flashcards
Gene Organisation in Eukaryotes -
Which part of a Eukaryotic gene carries instructions for protein synthesis?
= Exons
Which part has no instructions for protein synthesis?
= Introns
Which sections are spliced out (removed)?
= Introns
What protects the ends after splicing?
= 5’ Cap & 3’ Poly A Tail
Gene Organisation in Bacteria (a prokaryote) -
What are genes organised into in bacterial cells?
= operon
Do several genes share a promoter in bacteria?
= yes
Do bacteria have a membrane-bound nucleus?
= no (free floating)
what is Gene Expression?
Gene Expression is the process of how genes become expressed (used) to make proteins.
The process of gene expression(the synthesis of protein) occursthrough two stages, what are these stages?
Transcription = Converting DNA to mRNA Translation = converting mRNA to Proteins
where does Transcription occurs
Transcription occurs in Eukaryotic and Bacterial Cells.
what does Transcription convert
Transcription converts DNA to RNA (mRNA)
what is Transcription
the process where information is transcribed from the gene into a molecule of messenger RNA to later be translated into proteins.
where does Transcription occur
occurs in the nucleus in Eukaryotes and in the cytoplasm in Prokaryotes.
