A polymer is a long molecule consisting of many identical or similar building blocks linked by covalent bonds - … Prepolymer – A molecular unit reduced to the degree that it can be manipulated before polymerization. for distance learning. There are four basic kinds of biological macromolecules: carbohydrates, lipids, proteins, and nucleic acids. From a biological viewpoint this is simply because there is only a very limited set of chain lengths that exists in nature (~2-20 or so) and also even numbered chains are much more common than uneven numbered ones. 36 terms. Sporophylls (whether they are microphylls ... Transduction is the process by which foreign DNA is introduced into a cell by a virus or viral vector. These products include bottles, pipes, plastic containers, insulated wires, clothing, toys, and non-stick pans. Campbell Biology by J.B. Reece, L.A. Urry, M.L. chapter 10 general biology- cell reproduction. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. These monomers (the starting materials) are often alkenes. For more details, see our Privacy Policy. In dehydration synthesis, bonds are formed linking monomers together while losing water molecules. It is a commonly used term in biology, just as it is in chemistry. macaylat20. Monomers can have linear or branched configuration. The longer a polymer chain, the heavier it will be. The variation in the form of macromolecules is largely responsible for molecular diversity. Addition polymers are made from molecules containing C=C bonds. 36 terms.
