C) Polymorphism
D) Microsatellite

Question

Microsatellites are a type of molecular marker that consists of short, repetitive sequences of nucleotide bases (usually 1-6 base pairs). They are found mainly in noncoding regions of DNA, and the number of repeats can vary widely between individuals, making them useful for identifying genetic differences and studying population genetics. SNPs (single nucleotide polymorphisms) are another type of molecular marker, but they involve single base pair changes rather than repeated sequences. DNA barcodes are short, standardized DNA sequences used to identify species, and polymorphisms refer to any genetic variation between individuals or populations.
