Gambar
Gregor Mendel is usually considered to be the founder of modern genetics. Though farmers had known for centuries that crossbreeding of animals and plants could favor certain desirable traits, Mendel's pea plant experiments conducted between 1856 and 1863 established many of the rules of heredity. An Augustinian monk living in what is now the Czech Republic, Mendel had access to an experimental garden in which he could breed “true” lines of pea plants and patiently wait for them to crossbreed in specified combinations. He worked with seven characteristics of pea …

Amino acid

Amino acids are molecules that are the building blocks of proteins. They have a specific chemical makeup and can be produced by cells or ingested through diet. By the 1950s, scientists had agreed upon a list of twenty amino acids. That list still stands today, though it is possible that more will be discovered and named. List of Amino Acids:
alaninephenylalalinelysineprolinethreoninecysteineglycineleucineglutaminevalineaspartic acidhistidinemethionineargininetryptophaneglutamic acidisoleucineasparagineserinetyrosine
Base
A nucleotide base (guanine, adenine, cytosine, and thymine) is one of the building blocks of DNA, along with phosphates and sugar. These substances will join together to determine the order of proteins in each organism.���������������������…
