A bacterium of choice by Frederick Griffith was S. pneumoniae cells also known as Pneumococcus bacteria. This is due to the growth of bacteria inside the body of a host regardless in the form of either solid or liquid cultures. In 1928‚ Frederick Griffith studied and published his findings on the different strains of Pneumococcus bacteria. There were 2 in particular that looked different; S and R. The R colonies has rough surface whereas the S colonies have smooth surface. Intrigued by the experiment

gram-negative and gram-positive bacteria are and what it’s composed of. Gram-positive bacteria take up the class of bacteria that stain crystal violet in the method of bacterial differentiation. Where gram-negative bacteria are a class of bacteria that does not retain crystal violet. Instead they are counter-stained pink by Safranin‚ and because of this‚ identifying positive is possible. One of the many differences between gram-negative and gram-positive bacteria is their peptidoglycan. Which are

A. The typical human mouth contains a writhing orgy of bacteria. Most of these. Most of these microscopic organisms are bengin‚ and some are even beneficial‚ but one particular variety is a conspicuous troublemaker: Streptococcus mutans. These ubiquitous bacteria thrive on sugars in the mouth‚ which they consume while excreting lactic acid. This acid is responsible for the great majority of tooth decay in humankind because it erodes the enamel and dentin of the teeth. B. A Florida-based company

Describe how Bacteria decode its genetic information to produce proteins? Intro(10mins) Bacteria belongs to a group of organism that lacks cell nucleus and membrane bound organells. This group of organisms are termed as prokaryotes. Prokaryotes follows the central dogma of molecular biology first proposed by Francis Crick in 1958 to synthesize proteins from mRNA through a process called translation and the mRNA is being synthesized from the DNA by another process called Transcription.
