DNA is an example of a macromolecule, i.e. a large molecule with a special shape, which is built up from many smaller parts called sub-units .If you could magnify part of a nucleus, you would see the DNA molecule looking like a twisted rope ladder - a double helix. The two strands forming the sides of the ladder give it a strong yet flexible structure, which does not vary along its length. Stretched between these are the "rungs" of the ladder, the parts of the DNA molecule which vary, and so the differences carry genetic information. These parts are made up of sections called bases, which fit together in pairs. Single section of DNA The 4 bases (so called because on their own they react with acids) are also usually known by their initials, as shown alongside: A (adenine), paired with T (thymine) and C (cytosine) paired with G (guanine).
Poly nucleotide chain .
Yes, the DNA molecule is made up of segments of coding called Genes. Each gene codes to make a different protein or genetic characteristic.
A molecule contain two or more atoms of chemical elements; each molecule has a specific formula.
Each lipid molecule is composed of three fatty acids and one alcohol (monomer).
no they do not repel each other
Poly nucleotide chain .
Hemoglobin is a protein with repeating segments called heme, each of which contains an iron atom, which is the active site where oxygen can be carried.
The four nitrogen bases, Guanine, Cytosine, Thymine, and Adenine. Thymine and Cytosine are pyrimidines and Guanine and Adenine are purines. Thymine bonds with Adenine and Cytosine bonds with Guanine.
each sequence of three base pairs (rungs) forms the code for an amino acid. So the order of the rungs determines which amino acids are in and the order of the amino acids in every protein in your body.
Perpendicular line segments are line segments that cross with each other and form angles of 90 degrees.
15 body segments.
When 2 line segments are parallel to each other. If the lines did keep on going they would never touch each other
Yes, the DNA molecule is made up of segments of coding called Genes. Each gene codes to make a different protein or genetic characteristic.
Polygon
A recangle has 4 line segments. (Each side is a line segment).
Two nitrogen bases are linked together to form the "rungs of the ladder". The four possible nitrogen bases are Adenine, Thymine, Guanine and Cytosine, assigned A, T, G and C. A will always be paired with T, and G with C. The bases (A, T, G and C) are attached to the five-carbon sugar deoxyribose and a phosphate group, which make up the framework of the DNA molecule.
Bronchopulmonary segments is the division of the lobe of a lung. Each segment of the lobe is supplied by it's own artery.
