PCR, polymerase chain reaction, is the fastest way to artificially (in a laboratory) multiply few copies of DNA into many, in order to create enough of a sample to use for other genetic testing.
It is used quite often in forensic science, such as magnifying a small recovered sample of DNA from body fluids or tissue samples at a crime scene, into a vastly greater quantity of DNA for identification of suspect(s) or victim(s).
Answer AND Explanation:
Proteins are formed from the translation of mRNA to amino acid. Each set of 3 nucleotides make up a codon that codes for a specific amino acid. Frameshift mutations can also impact the formation of the protein. A change in a nucleotide does not always change the amino acid or protein because some amino acids have more than one set of 3 nucleotides that code for them. Valine, for example, is coded for by GUU, GUC, GUA and GUG. A change in the last nucleotide wouldn't affect the amino acid formed. However,GAG codes for glutamic acid.
D; because the cells dna is not in the nucleus
Answer:
Triglycerides are esters in which three molecules of one or more different fatty acids are linked to the alcohol glycerol; they are named according to the fatty acid components; e.g., tristearin contains three molecules of stearic acid, and oleodistearin, one of oleic acid and two of stearic acid.
