Bacterial cells do not normally take up plasmids. However, scientists can use tricks to make them do so.

What is plasmid copy number?

The copy number reflects the average number of copies of a certain plasmid inside a host cell. The higher the copy number, the more efficient the plasmid is at replicating itself. Researchers using plasmids as vectors usually choose high copy number plasmids as their vectors since you can get a large number of plasmids from relatively fewer cells in less time.


Are cones photoreceptors that operate best in bright light?

Cones are photoreceptor cells in the retina that are responsible for color vision and functioning best in bright light conditions. They are less sensitive to light compared to rods, which are specialized for low-light conditions.


Why do most predators have a greater amount of rod cells in their eye than cone cells?

Because cone cells are activated by light, that is why our pupils get smaller and larger, to let more or less light in, where as rod cells have no need for light, and are better for seeing in the dark, wich is a valueble abilaty when you are a pretator.


Do body cells have less chromosomes than sex cells?

No, somatic (non-sex) cells have twice the number of chromosomes that sex cells have.


What happen to cells in dilute urine sample?

In a dilute urine sample, cells such as red blood cells, white blood cells, and epithelial cells may appear less concentrated or even lyse due to the increased water content. This can make it challenging to interpret the presence of these cells accurately, as they may be less visible and their identification may be less reliable.

What is a plasmid and why is it useful to researchers?

Plasmids are important in the phases of bacterial genetics because plasmids are the small circle of DNA for bacteria and is responsible for storing and studying genes. Plasmid is used as the vehicle to genetically engineer bacteria to produce insulin.

Why does blood thicken in certain medical conditions?

Blood can thicken in certain medical conditions due to an increase in the number of red blood cells or proteins in the blood, which can make it more viscous and flow less easily. This can happen in conditions like dehydration, polycythemia, or certain genetic disorders.
