Polyethylene

Polyethylene

________ is an example of a homopolymer, which is a polymer composed of only one monomer type.

Nucleotides

________ are made up of three groups: a base, deoxyribose, and a phosphate group.

styrene

Because ________ and butadiene are separate monomers, SBR is classified as a copolymer, which is a polymer made up of two or more monomers.

Tyvek

________ is used for home isolation as a specially treated kind of polyethylene.

Erwin Cargaff

tested and observed certain regularities of DNA molecules obtained from different sources.

NH2

A substance with at least one amino group (________) and at least one carboxyl group are known as an amino acid.

hydrogen bands

While ________ can build up between any two bases called base pairs, the best connections between adenine and thymine are found between cytosine and guanine, and Watson and Crick have found.

Polymers

________ began to develop in the 1920s by studying the puzzling behaviour, which included wood, gelatine, cotton and rubber.

Proteins

________ are polymers of amino acids that are involved in practically every biological process.

Polymer chemistry

________ emerged in the 1920s as a result of research into the perplexing behavior of various materials like wood, gelatin, cotton, and rubber.

Rules of Chargaff

Adenine (purine) is the same as Thymine (pyrimidine); i.e., A = T or A/T = 1.

Cytosine (pyrimidine) is equal to guanine (purine); in other words, C = G, or C/G = 1.

The total number of bases of purine equals the total number of bases of pyrimidine, i.e. A + G = C + T
