DNA, or deoxyribonucleic acid, is found in the nucleus of a cell. Also, a small amount of DNA known as mitochondrial DNA, or mtDNA, is found in the mitochondria of the cell because the 37 genes found in mtDNA are necessary for the mitochondria to function. Every living creature has unique DNA that contains its biological instructions.Continue Reading
Each human is comprised of not millions, but trillions of cells. Each cell has its own nucleus that holds a copy of the DNA for that individual. The nucleus of the cell is similar to the cockpit of an airplane; t is the command center where everything happens. Any action the cells take, whether that be to grow or replicate, begins in the nucleus. It is also the place where DNA is stored safely away. In order to protect the DNA, a membrane known as the nuclear envelope surrounds the DNA in the nucleus to separate it from the rest of the cell.
The mitochondria of a cell where mtDNA is found creates enzymes and molecules like RNA and tRNA, which are involved in making amino acids. Without the mtDNA, the mitochondria could not function because the instructions to create these enzymes and molecules is housed in the mtDNA.Learn more about Biology
Regular fingerprinting methods conduct tests and make records of finger and thumb prints of an individual, while DNA fingerprinting tests the deoxyribonucleic acid of a person, which is located within the nucleus of all cells in the body, states The Tech Museum of Innovation. During DNA fingerprinting, scientists analyze the genetic material to determine the differences in DNA between individuals.Full Answer >
A diploid cell is a cell that contains a set of chromosomes from each parent so that is has two complete sets of chromosomes. Diploid cells reproduce using a process known as mitosis. This procedure creates cells that are an exact replica of the parent cell.Full Answer >
A haploid cell is one that contains only a single set of chromosomes. In humans, a haploid cell consists of 23 chromosomes. Both sperm and egg cells are haploid.Full Answer >
Chromosomes can be found in the nucleus of every plant and animal cell; these combinations of DNA and protein are essential components of genetic information. DNA is a long chain of genetic information that would not be able to fit inside a cell without the structural assistance of chromosomes, and this information helps determine a plant or animal's individual traits, including physical characteristics and behavioral capabilities. The DNA that is contained in chromosomes is passed from parents down to offspring.Full Answer >
