fire.biol.wwu.eduPrior to staining with dyes, cells must be "fixed." Fixation is a process of killing, immobilizing and preserving the bacterial cell. For bacteria, heat fixation is most common; however, chemicals such as formaldehyde, glutaraldehyde, acids and alcohols can be used. Dyes used to stain bacterial cells are organic compounds which have

is.muni.cz1. Bacterial cell (morphology, staining reactions, classification of bacteria) The protoplast is bounded peripherally has a very thin, elastic and semi-permeable cytoplasmic membrane (a conventional phospholipid bilayer). Outside, and closely covering this, lies the rigid, supporting cell wall, which is porous and relatively permeable.

www.eagri.org1976). Each bacterial cell probably contains about a hundred or more different types of tRNA. The function of tRNA is to carry amino acids to mRNA during protein synthesis. Each amino acid is carried by a specific tRNA. Since 20 amino acids are coded to form proteins, it follows that there must be at least 20 types of tRNA.
