Where is DNA located in Bacteria?

From the tiniest bug, to the tallest oak tree, and largest mammal, DNA certainly gets around. What is so incredible about this molecule is its similarity in structure and composition in all living things. This article takes a peek inside cells to find out where DNA is found. Human Cells Nucleus DNA can be found inside the nucleus of every cell, apart from red…

Similarity Between Bacteria and fungi

Similarity Between Bacteria and fungi

In order to survive, organisms produce small molecules known as primary metabolites which help it to grow, develop and reproduce. Examples include nucleic acid used to make DNA, amino acids to make proteins, and simple sugars. Once the organism is established it will often start to produce secondary metabolites . Secondary metabolites are not vital for survival…

Mitochondria in Bacteria

About 1.5 billion years ago, primitive bacteria took residence inside larger cells, resulting in an intimate relationship that would mold the evolution of more complex, multicellular beings. The bigger cell was eukaryotic, meaning it contained organelles - structures surrounded by membranes, but the prokaryotic bacterial cell had no such arrangement. The bigger…

Fungus is a Bacteria

Bacteria and fungi occur in all environments. In humans, these lifeforms can be harmless passengers, participate in beneficial biological processes, or cause disease. Bacterial and fungal infections affect people of all ages and range from minor to potentially life-threatening. Bacteria and fungi have similarities and differences that influence their disease-causing…

Does Bacteria have Cytoplasm

The structures of two prokaryotic cells. The bacterium (shown at the top) is a heterotroph , an organism that eats other organisms. Cyanophytes are autotrophs , organisms that make their food without eating other organisms. Most of these prokaryotic cells are small, ranging from 1 to 10 microns with a diameter no greater than 1 micron. The major differences between…

What are the Features of Bacteria?

Mosquitoes kill an estimated 700 people a year. If infected with viruses that cause diseases like chikungunya, dengue and Zika, mosquitos can transmit them to humans in one bite. Researchers have now pilot-deployed a new technique to control diseases transmitted by mosquitoes by making use of nature. It is one of the new tools WHO recommends for pilot deployment…

Bacteria and fungi Similarity

Bacteria and fungi Similarity

There exists very little similarity between Bacteria and Fungi as a whole. For starters, Bacteria are prokaryotes without any defined nuclei. Fungi are Eukaryotes, having a defined cellular nucleus, with the genomic DNA bound by a defined nuclear membrane. The modes of cellular metabolism are vastly different and so is the mode of reproduction. Very few fungi…

Information on Bacteria

In the future, it will be possible to carry out tests of new drugs on bacteria much more efficiently using microfluidic devices, since each of the hundreds and thousands of droplets moving through the microchannels can act as separate incubators. So far, however, there has been no quick or accurate method of assessing the oxygen conditions in individual microdroplets…

Nucleus of Bacteria

Nucleus of Bacteria

A unique feature of eukaryotic cells, which distinguishes them from bacteria, is the presence of a membrane-bound nucleus that contains the chromosomal DNA (illustrated; image credit). Surprisingly, a nucleus-like structure that forms during viral infection of bacteria is the site of viral DNA replication (link to paper). During infection of Pseudomonas bacteria…

Bacteria cells Have a Nucleus

Photo by: icholakov Hundreds of thousands of bacterial species exist on Earth. They can be found in very diverse environments ranging from cold to hot and alkaline to acid. They live in soil, in water, and on rocks. They exist deep in the earth, high on mountains, and in deep-sea vents. They grow on and in other bacteria, worms, insects, plants, animals, and…

Does Bacteria have a Protein Coat

EMBL discovery could yield evolutionary insights and new model organism This electron microscopy image shows Gemmata obscuriglobus . This and other PVC bacteria, the EMBL scientists discovered, have membrane-coat proteins associated with the membranes of subcellular compartments like the one shown in green, in which vesicles can be seen as dark green regions…

Microscopic Bacteria

The chaotic movements of bacteria could be tamed to create electricity, powering miniature future gadgets, such as medical devices or other nanoscale machines. A newly published paper from researchers at Oxford University explains how to turn a fluid soup of bacteria into a kind of miniature wind farm. The team dropped a minuscule array of 64 rotors into a microfluid…

Yeast Bacteria or Fungus

Most healthy vaginas have yeast. But sometimes your yeast grows too much and leads to an infection. Yeast infections can be very irritating and uncomfortable. What causes yeast infections? A vaginal yeast infection, which is also sometimes called vulvovaginal candidiasis, happens when the healthy yeast that normally lives in your vagina grows out of control…
