Given the remarkable diversity of bacteria and archaea - and recognizing that there is probably even more diversity that has yet to be discovered - describe which of the prokaryotes catches your interest and why. For example, are you fascinated by the ones that are beneficial, or are the pathogens more interesting to you? Do you ponder whether Archaea might give clues to the origins of life, or are you more interested in the prokaryotes that keep our planet healthy? Did any of the prokaryotes highlighted in the activities particularly surprise (or amaze) you?

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
