Read about Biology
In A-Level biology, a monomer is a small molecule that can bind chemically to other similar molecules to form a larger molecule known as a polymer. Think of monomers as building blocks, like LEGO pieces, that come together to create complex structures.
An allele is a version of a gene in A-Level biology. Genes can have different forms or variations, which are called alleles. For example, the gene for eye color might have an allele for blue eyes and another for brown eyes. Alleles are responsible for the diversity in traits among individuals.
A monoclonal antibody is a type of antibody that is identical and produced from a single type of immune cell in A-Level biology. These antibodies are incredibly useful in medical treatments and research because they can be designed to target specific cells or proteins.
Clonal selection is a process in A-Level biology where a particular cell, usually an immune cell, is selected and cloned to fight an invader like a virus. When your body detects a foreign substance, it selects the right cell to deal with it, and then makes lots of copies of this cell to attack the invader effectively.
