The Structure of the Genome Flashcards
1
Q
What is the genome?
A
A genome is the total hereditary genetic information found in the DNA.
2
Q
What is the genome made up of?
A
Exons (coding regions)- genes that code for protein.
Introns (non-coding)- other DNA sequences that don’t code for proteins.
3
Q
What happens to introns in the genome?
A
Non coding regions removed during RNA splicing.
4
Q
What are the roles of introns on the genome?
A
Regulate transcription (turns transcribed genes on/off)
Transcribed but no translated (rRNA/tRNA)
No known function.
5
Q
What are the two ways of transferring genomes?
A
Vertical
Horizontal
6
Q
Vertical
A
Parent to offspring (eukaryotes)
7
Q
Horizontal
A
Same generation (prokaryotes)
8
Q
Vertical Inheritance
A
Sexual methods may vary.
Asexual methods have no variety.
