Question

What are SNPs in the context of human genetic variation?

Options

• Sequential nucleotide points

• Structural nucleotide positions

• Segmented nucleotide patterns

• Single-nucleotide polymorphisms

Answer 1

SNPs stands for single-nucleotide polymorphisms, which are variations in a single nucleotide at specific positions in the DNA sequence. Many variation sites in the human genome are due to SNPs, and they represent one of the primary sources of genetic diversity among individuals, contributing to the 0.1% variation observed between humans.
