Muscular system in our body is responsible for the movement. Digestive system in our body is responsible for moving food.
An unknown mtDNA sample sample is matched to a sample of mtDNA that was found at the crime scene.<span> This is how mitochondrial DNA (mtDNA) typing is used in forensic science.</span>
<span>Unlike nuclear DNA typing, mtDNA isolation is quite easy because its number is quite large. mtDNA copies rang from 100 to 10,000 per cell. It is also more stable and stronger than the nuclear DNA; that is why even unsolved cases from years ago use mtDNA typing as reference for possible conclusion.</span>
Answer:
Base
Explanation:
Deoxyribonucleic acid, DNA, is one of the four major biomolecules in living organisms. It is a polymer made up of monomers called NUCLEOTIDES. The nucleotides that make up a DNA molecule is composed of three substances namely: Sugar (deoxyribose), nitrogenous base, and a phosphate group.
However, among these three components of the nucleotide monomer, NITROGENOUS BASE is the only portion that is not the same in every DNA molecule. There are four nitrogenous bases in nature viz: Adenine, Guanine, Cytosine and Thymine. These four bases can be alternated in a DNA molecule.
Note that, phosphate group and deoxyribose sugar are constant in every DNA.
Answer:
Facilitated diffusion (also known as facilitated transport or passive-mediated transport) is the process of spontaneous passive transport (as opposed to active transport) of molecules or ions across a biological membrane via specific transmembrane integral proteins.
