Mutation In Genetics - #194
In biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal dna. Scientists study how much of what makes us us is genetic. Mutations are changes in the genetic sequence, and they are a main cause of diversity among organisms. Some mutations can lead to genetic disorders or illnesses. Genes are made of deoxyribonucleic acid (dna), a long molecule . Complementation from www.wormbook.org Genetic mutations are changes to your dna sequence that happen during cell division when your cells make copies of themselves. While a mutation is defined as any alteration in the dna sequence, biologists use the term single nucleotide polymorphism (snp) to refer to a single base pair . These small differences in dna sequence make every individual unique. Genes are made of deoxyribonucleic acid (dna), a long molecule . By natalie wolchov...
