Answer 3

DNA - deoxyribonucleic acid, a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.

Answer 4

im not good at this kind of stuff tbh :/ sorry

Answer 5

i am

Answer 6

The DNA that is found in the cell structures, known as mitochondria, is responsible for providing the energy that the cell needs to function. Many organisms also have sets of DNA that are responsible for aiding in reproduction. These are known as sex cells and help create a new organism. In humans and many other animals, the sex cells combine to form two separate sets of DNA that will make up the cells of the new organism. Some organisms only take DNA from the mother cells.
DNA is made up of parts called nucleotides. These parts are responsible for building the rest of the cell structures that are present in organisms. Nucleotides are made up of phosphate groups, sugar groups and a nitrogen base. A strand of DNA is formed when these nucleotides link together. The sugar groups and the phosphate groups alternate throughout the entire strand of DNA. The nitrogen base is the base of the DNA strand and remains constant throughout the entire strand.

Answer 7

Mitochondrial DNA is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, adenosine triphosphate (ATP).

Answer 8

CODIS uses two indices to generate investigative leads in crimes that contain biological evidence—the forensic index contains DNA profiles from biological evidence left at crime scenes, and the offender index contains DNA profiles of individuals convicted of violent crimes.

Answer 9

A complimentary base is either of the nucleotide bases linked by a hydrogen bond on opposite strands of DNA or double-stranded RNA: guanine is the complementary base of cytosine, and adenine is the complementary base of thymine in DNA.

Answer 10

RFLP is a method used by molecular biologists to follow a particular sequence of DNA as it is passed on to other cells. RFLPs can be used in paternity cases or criminal cases to determine the source of a DNA sample and to track disease progression.
