MCQ
Which ones are simple sequence repeats (SSRs):
- AMinisatellite sequences
- BMicrosatellites
- CPseudogenes
- DMultiple gene family.
Explanation:
Simple sequence repeats (SSRs), sometimes described as genetic 'stutters,' are DNA tracts in which a short base-pair motif is repeated several to many times in tandem (e.g. CAGCAGCAG). These sequences experience frequent mutations that alter the number of repeats similar to Multigene Family, a set of genes descended by duplication and variation from some ancestral gene.
