Genomes and genomics Flashcards
What is a genome?
Entire compliment of hereditary genetic information
What is the genome made up of?
Genes
Regulatory sequences
Structural DNA
“Junk” DNA
What is DNA measured in?
Base pairs (bp)
What is the C-value paradox?
Genome size is not correlate with organismic complexity or the number of genes
