What is DNA?
- DNA. DNA stands for deoxyribonucleic acid. It is a chemical made up of two long molecules. ...
- Genes. Genes are short sections of DNA. Genes carry information for particular characteristics, such as ear shape or eye colour.

How is a DNA fingerprint made quizlet?
How is DNA fingerprinting made? Cutting DNA with a restriction enzyme and separate the fragments with gel electrophoresis.
What DNA provides?
DNA contains the instructions needed for an organism to develop, survive and reproduce. To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies.
What is a DNA strand?
DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases: adenine (A), cytosine (C), guanine (G) or thymine (T).
What type of molecule makes up DNA?
nucleotide basesDNA is a linear molecule composed of four types of smaller chemical molecules called nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T). The order of these bases is called the DNA sequence.
What is the name of the structure of DNA?
DNA, or deoxyribonucleic acid, is the central information storage system of most animals and plants, and even some viruses. The name comes from its structure, which is a sugar and phosphate backbone which have bases sticking out from it--so-called bases.
How many bases are in DNA?
The bases go by the names of adenine, cytosine, thymine, and guanine, otherwise known as A, C, T, and G. DNA is a remarkably simple structure. It's a polymer of four bases--A, C, T, and G--but it allows enormous complexity to be encoded by the pattern of those bases, one after another. DNA is organized structurally into chromosomes ...
What is DNA made of?
The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), and thymine (T). The two strands are held together by bonds between the bases; adenine bonds with thymine, and cytosine bonds with guanine. The sequence of the bases along the backbones serves as instructions for assembling protein and RNA molecules.
What are the four bases that are attached to sugar?
Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), and thymine (T). The two strands are held together by bonds between the bases; adenine bonds with thymine, and cytosine bonds with guanine. The sequence of the bases along the backbones serves as instructions for assembling protein and RNA molecules.
What is African American DNA detective?

" DNA methylation-based diagnostics have the potential to substantially change the way physicians first diagnose and later treat cancer patients," said Professor Robert Brown, Ph.D., University of Glasgow.
Who is the founder of the African American DNA Roots Project?
Among them: Georgia Dunston, founding director of the National Human Genome Center at Howard University; Bruce Jackson, founder of the African-American DNA Roots Project; and Charles Crutchfield, a clinical dermatologist who used genetic research to develop a treatment for psoriasis.
