Explanation:
this is the compkementary strand
Answer:
Given:
Number of colonies on plate = 40
Amount of DNA used for transformation = 100ng
Volume of competent cells used = 100ul
Total volume = 1ml (1000ul)
Volume plated for growth = 200ul
The amount of cells transformed per 1 µg of DNA is called the transformation efficiency
(CFU is colony forming units) => (number of colonies on plate/ng of DNA plated) X 1000 ng/µg = CFU/µg of DNA
Amount of DNA used for plating = 100ng * (200/1000)
= 100ng * (1/5)
= 100/5 = 20ng
Efficiency calculation = 40 colonies / 20ng = 2 colonies/ng
(2 colonies/ng) * (1000 ng/µg) = 2000 CFU/ug DNA
Transformation efficiency = 2000 Transformants / ug DNA
= 2 x 10³ Transformants / ug DNA
Explanation:
Efficiency of transformation is highest in the 100 pg-1 ng range, so Low transformation efficiency could be because of high amount of DNA used for transformation.
The best descriptions are those that correctly describe the terms or concepts ecology.
<h3>Which descriptions best fit the given terms?</h3>
The study of living things and their non-living is ecology.
The description of a given term provides information about that term or concept.
The best description of the given terms are as follows:
- Mutualism - a relationship where both organisms benefits
- Commensalism - a a relationship where one organism benefits and the other is unaffected
- Producers - organisms that make their own food
- Food web - show energy flow in an ecosystem
- Biome - a large area defined by climate and organisms that live there
- Stability - ability of an ecosystem to respond to change
- Exponential - growth pattern at constant rate
- Carrying capacity
- Food chain
- Limiting factor
- Parasitism
- Trophic levels
- Biodiversity
- Abiotic factors
- Population
- Climate
- Biosphere
- Consumers
- Keystone species
- Community
Therefore, the best descriptions are those that correctly describe the terms or concepts.
