DNA
What does DNA stand for?
What is the molecules that carry the body's genetic information
What are the four pairs of DNA bases that form in the double helix?
What is Adenine (A) Thymine (T) Guanine (G) Cytosine (C)
What is DNA typing?
A method in which DNA is converted into a series of bands that ultimately distinguish each individual.
What is DNA extraction?
What is DNA isolation is a process of purification of DNA from sample using a combination of physical and chemical methods.
DNA
What is deoxyribonucleic acid, a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
What is DNA made of?
What is DNA is made up of molecules called nucleotides.
What is a mutation?
What is A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.
Uses of DNA Profiling?
What is to identify potential suspects
Does DNA have any color?
What is no.
Chromosome
what is a threadlike structure in the cell nucleus composed of DNA, along which the genes are located
What are Nucleotides made of?
What is each nucleotide contains a phosphate group, a sugar group and a nitrogen base
What makes up each rung of the ladder?
What is The rungs in the DNA "ladder" are caused by the complementary base pairs--adenine, quanine, cytosine and thymine, forming hydrogen bonds with their paired base on the other side.
Uses of DNA Profiling?
What is to exonerate individuals.
Do only living things contain DNA?
What is only organic things.
Restriction Fragment
what is a different fragment lengths of base pairs that result from cutting a DNA molecule with restriction enzyme
What are the four Nitrogen Bases?
The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C).
Is there mostly empty space between the atoms in a DNA double helix?
What is yes, there is mostly space between the atoms.
Uses of DNA Profiling?
What is to identify crime and causality victims.
why is DNA considered an organic molecule?
What is because of the monomers and molecules organic if it has a carbon backbone
Restriction Enzyme
What is a chemical that acts as scissors to cut DNA molecules at specific locations.
What aspect of DNA defines the role and function of a DNA molecule?
What is Amino Acids.
How do proteins recognize specific sequences of DNA?
What is Proteins recognize a particular sequence by having a surface that is chemically complementary to that of the DNA
What is the system for which your DNA profile is kept in?
What is CODIS.
When was DNA extraction first used?
What is The first isolation of DNA was done in 1869 by Friedrich Miescher.
Human Genome
What is the order of bases on all twenty-three pairs of human chromosomes
