this depends on whether you are trying to make chemically competant cells or electrically competant cells. the process of making a cell "competant" means that they are capable of accepting 'donor' DNA
u count dead cells stained by trypan blue. trypan blue enters the cells only when it has died since when a cell dies it looses its property of controlling selective inlet of micromolecules. When cells r alive it doesn't allow inlet of trypan blue so viable cells r not stained. viable cells = total cells - trypan blues stained cells Nitin Ghoshal Dept of Biotechnology NEHU, Shillong, Meghalaya, India
A blue whale is made up of multiple cells. It is a multicellular organism, composed of different types of specialized cells that work together to carry out various functions necessary for the whale's survival.
Generally most of the bacteria have the ability to take up DNA which is present freely in the environment. This is called Competence. It is genetically acquired. But some cells do not exhibit natural competence and they are treated with a suitable chemical like CaCl2 to make their cell wall relatively permeable to DNA. We can make any cell competent in vitro and introduce our desired gene which is taken up by the competent cell. To test the efficiency of our treatment, we may introduce a marker gene like gene for antibiotic resistance such as Tetracyclin onto the desired gene and grow the treated cells on Tetracyclin medium so that only the cells that have taken up the DNA survive.
When a fixed smear of bacterial cells comes into contact with methylene blue and all cells appear blue under the oil lens, this is an example of a basic staining technique. Methylene blue is a cationic dye that binds to the negatively charged components of bacterial cells, allowing for visualization. This staining method helps to highlight the morphology and arrangement of the bacteria, making them easier to observe under a microscope.
XL1 in roman numerals stand for 41.
Yes, cells can be transformed when they are in a competent state. Competent cells have an increased ability to take up foreign DNA, making them more likely to undergo transformation when exposed to external DNA molecules. This process is commonly used in laboratories for genetic engineering and cloning.

The Canon XL1 Digital Camcorder is sold on the Amazon website. The average price for the Canon XL1 Digital Camcorder around $500 when purchased used from sellers who sell through Amazon.
cells which readily accept a foreign DNA through a process called transformation
yes
Competent cells are bacterial cells that have been treated to make them capable of taking up foreign DNA, such as plasmids. These cells can be used for various genetic engineering techniques, such as transformation.
The best replacement options for Canon XL1 batteries are genuine Canon batteries or high-quality third-party batteries that are compatible with the XL1 camera. It is important to choose batteries that are reliable and have good reviews to ensure optimal performance and longevity.

it will be really good
