Answer:
There are also various direct methods of preventing landslides; these include modifying slope geometry, using chemical agents to reinforce slope material, installing structures such as piles and retaining walls, grouting rock joints and fissures, diverting debris pathways, and rerouting surface and underwater drainage.
Explanation:
Answer:Single nucleotide polymorphisms or SNPs (pronounced "snips") are DNA
sequence variations that occur when a single nucleotide (A,T,C, or G) in the
genome sequence is altered (point mutation).
SNPs do not cause disease, but they can help determine the likelihood that someone will develop a particular disease.
Because single base mutations can either create additional restriction sites or destroy pre-existing sites, DNA preparations from different individuals frequently exhibit different patterns of size distribution of restriction fragments that hybridize with a particular probe. These differences are called
restriction fragment length polymorphisms (RFLPs).
