The overall shape of a bacterial cell is determined by which of the following? a. Cytoskeleton b. Cell wall c. Nucleoid d. Cell surface membrane Bacterial Structure: Bacteria are prokaryotic cells. There are three distinct s...
of the grana creates a firm plastid body and confers the characteristic lens-like form to the chloroplasts [19,20]. The presence of components of a plasto-skeleton, such as plant homologs of the bacterial FtsZ (filamentous temperature sensitive Z) has been demonstrated and presently forms an ...

The ability of Bacillus subtilis to form subterminal endospores makes it unique among the other members of the genus Bacillus. The formation of an endospore is a response to nutrition deprivation or harsh environmental conditions. Bacillus subtilis has a single chromosome that replicates bidirectionally...
Describe the principle behind the staining technique that is used to differentiate bacteria based on the structure of their cell wall. How does the bacterial cell structure contribute to the mechanism of Gram staining? In the cell structure of bacteri...
Of the 473 genes in the genome of the bacterium with the smallest genome generated to date, 149 genes have unknown function, emphasising a universal problem; less than 1% of proteins have experimentally determined annotations. Here, we combine the result
The Great Wall: Peptidoglycan Is a Primary Determinant of Bacterial Cell Shape In Caulobacter, as in almost all bacteria, the peptidoglycan (PG) cell wall is both necessary and sufficient to maintain cell shape. The cell wall resides just outside the cytoplasmic membrane and is one large, coval...
Functional analysis of the gut microbiome using shotgun metagenomics suggests that microbial metabolism and downstream metabolic pathways are altered in PD. For instance, a systematic analysis of the gut microbiome of individuals with PD revealed impaired bacterial amino acid synthesis, increased levels ...
Formation of bacterial colonies was analyzed by mathematical models as an example of complexity in open systems. Variables such as cyclic production of chemoattractants and chemorepellents, due to the amount of available nutrients or waste, were considered. Long range chemical signalling such as quoru...
