DNA fragment who are protected by a DNA binding protein are not digest. one can see the sequence recongnition

wow.....what an answer?!

DnaseI digests DNA nondiscriminantly, but at low concentrations the DNaseI nuclease cannot digest as efficiently. Only the loosely packaged chromatin is digested. this is a method used to study chromatin (DNA) packaging. Sensitivity (Hypersensitivity) to DNaseI is usually associated with actively transcribed genes, where regulatory elements are accessible to regulatory proteins. baculoboy

Pure water and most chlorinated drinking water lacks the nutrients needed for bacterial growth. If the water is left uncovered though enough dust may get into the water for some bacterial growth.

All over the place. There are more bacteria in your body than there are human cells. They have also been found deep, deep underwater as well as in thermal hot springs, and areas of high salt concentrations.

No. You can only be infected with Gonorrhea if it infiltrates the internal parts of the body. The possible chances of getting Gonorrhea is through sexual intercourse, oral sex, and being injected with it.

The bacteria found in some bagged lettuce recently was E. coli.

L-15 cell culture medium is a type of basal medium commonly used for culturing a variety of mammalian, invertebrate, and plant cells. It contains essential nutrients, vitamins, and amino acids to support cell growth and maintenance. L-15 medium is often supplemented with additional components based on the specific requirements of the cells being cultured.

The basic shapes include circles, squares, rectangles, triangles, and ovals. These shapes serve as building blocks for more complex shapes and are commonly used in various mathematical and design applications.

Members of the genus Pseudomonas display the following defining characteristics: • Rod shaped •Gram-negative • One or more polar flagella, providing motility • Aerobic, although some species have been found to be facultative anaerobes (e.g. P. aeruginosa) •Non–spore forming • Positive catalase test

Vibrio fischeri is a gram-negative rod-shaped bacterium found globally in the marine environments. It has bioluminescent properties, and is found predominantly in symbiosis with various marine animals, such as the bobtail squid. It is heterotrophic and moves by means of flagella. Free living V. fischeri survive on decaying organic matter (see saprotroph). The bacterium is a key research organism for examination of microbial bioluminescence, quorum sensing, and bacterial-animal symbiosis.

Harmful bacteria can usually be found in environments that are warm, moist, and contain organic matter such as food, water, and soil. Common sources of harmful bacteria include raw meat, contaminated water, and unsanitary surfaces. Additionally, they can thrive in the human body, causing infections when the immune system is compromised.

Antibiotics are drugs that can kill bacteria by targeting specific mechanisms within the bacterial cell, such as disrupting cell wall synthesis or inhibiting protein synthesis. Common classes of antibiotics include penicillins, cephalosporins, tetracyclines, and fluoroquinolones. It's important to use antibiotics appropriately and as prescribed by a healthcare professional to avoid resistance and side effects.

The amount of bacteria that can contaminate a fomite (inanimate object) depends on various factors such as the type of surface, the duration of contamination, and the presence of other organic materials. Fomites can harbor enough bacteria to cause infections if they are not cleaned regularly and properly.

Bacteria are caused by living microorganisms that can thrive in various environments. They can be transmitted through various means such as person-to-person contact, contaminated food or water, and contact with infected surfaces. Certain factors like poor hygiene, crowded living conditions, and compromised immune systems can also contribute to the spread of bacteria.

The nucleus contains the cell's genetic material, organized as chromosomes, which carry the instructions for cell growth, development, and reproduction. It also contains the nucleolus, responsible for producing ribosomes, and is surrounded by a nuclear membrane that controls the movement of materials in and out of the nucleus.

The container used for growing mold or bacteria is called a Petri dish. It is a shallow, flat dish made of clear glass or plastic with a lid to create a controlled environment for the growth of microorganisms.

Glycerol is used in the estimation of boric acid because it forms a stable complex with boric acid, making it easier to measure the boric acid content in the sample. This complex formation helps prevent interference from other substances in the sample, leading to more accurate results.

Characteristics of bacteria are prokaryotes, meaning they do not have membrane bound organelles, peptidoglycan cell wall, and asexual reproduction, meaning they only need themselves to multiply.

A coliform count is a microbiological assay of the number of coliform-type bacteria living in a certain sample. This is often used as a measure of fecal contamination of water supplies.

Sure! Three pathogenic bacteria and their respective shapes are:

1. Escherichia coli (E. coli) - rod-shaped
2. Streptococcus pyogenes - spherical (cocci)
3. Mycobacterium tuberculosis - rod-shaped (bacilli)

Bacteria species can grow at varying rates on agar plates, depending on factors such as temperature, nutrient availability, and the specific species of bacteria. Under optimal conditions, some bacterial species can double in population every 20 minutes, while others may take several hours to days to form visible colonies on agar plates.

Streptococcus is a gram-positive bacteria that causes various illnesses in human bodies. To answer the question briefly, the streptococcus is caused by other streptococcus, which asexually reproduces by binary fission to get another streptococcus. To answer the question regarding the disease, the disease is simply caused by the bacteria.

Yes, an organism can be a fermenter and be both MR (methyl red) and V-P (Voges-Proskauer) negative. Fermentation is a metabolic process that converts sugar into acids, alcohols, or gases, but the MR and VP tests specifically evaluate different aspects of sugar metabolism that may not be related to fermentation. So, an organism can still ferment sugars without giving positive results on these tests.

by application of heat and a mordant, the cell can be stained. the purpose of heating is to soften the waxy material of the cell wall and allow the stain enter the cell. rock on University of Luzon!
