Slide 10 Flashcards
Example of polyploidy
Down syndrome (trisomy 21)
Can polyploidy cause new species to appear
Yes
SPARCL is an example of _____
Gene duplication event
Pericentric vs paracentric inversion
Pericentric inversion includes centromere
Paracentric inversion does not include centromere
Paracentric for this reason should be safer
Whole genome shotgun approach vs next generation sequencing
Rapid DNA sequencing by randomly fragmenting the genome, assembling overlapping sequences to reconstruct the entire genome.
Next generation: more advanced and efficient iteration, enabling faster and cheaper sequencing of entire genomes or specific regions
Genomes vary in
Size
Number of genes
Genome desntiy
Describe the relationship between genome size and number of protein coding genes
Proportional
Define transposable elements
Stretches of DNA that can move from one location to another within the genome (75% in humans)
Does gene number explain complexity?
No! Humans only have 50% more genes than drosophila melanogaster
Why is alternative splicing useful?
Allows one gene to code multiple proteins
