Answer: True, both of the given statements are true.
Explanation:
1. Nearly all the environment contains microorganism whether it is soil, air, water or any other surface. They have the ability of live in the extreme conditions.
There are different forms of bacteria found at different places. Some of them are thermophiles that at found in extremely hot conditions such as thermal vents.
The organism like Psychrophiles are the microorganisms that have the ability to survive at lower temperatures. Example: bacteria found in polar regions.
2. A culture can be defined as a pure culture if it has an unadulterated species of bacteria. It has no contamination and if a small inoculum from the pure sample is streaked on a plate then a pure culture of the sample is obtained.
This should be done in an aseptic condition so that the bacterial species should be free from contamination.
Answer:
Following are the responses to these question:
Explanation:
The heterokaryons were cells of diverse traditions or more nuclei. A heterokaryon cell with network cells (donor and receiver nuclei) sharing a common costly to treat is produced whenever a node containing GFP-tagged protein (donor cell) is merged to a cell non express the GFP-tagged proteins (recipient cell). Unless the intracellular scram nuclear exists, GFP must leave the GFP atoms, be shipped to the cytosol, and be exported to a nucleus with emission of GFP protein (recipient nucleus). It is obtaining nuclear has been beginning to release the GFP protein.
Unless the GFP protein doesn't display a nucleus costly to treat, this is not distributed across time in the metal target. By either sole dissemination through nuclear pores or receptor-mediated routes, protein yelling from nuclear to emotional exhaustion can occur. That GFP proteins are shown in a nucleus only suggests a path via a transmitter. For chloroplast, though, protein disperses via nuclear envelope. It is not the case. It should have nuclear foreign trade signals when ferrying between the nucleus and cytoplasm.
Cycloheximide is indeed a medicine that stops protein expression without elongating. For heterokaryon cells, it inhibits fresh protein synthesis. It makes visualization of a nanoparticle cell of only old pre-existing molecules (before cycloheximide diagnosis). That post GFP substance is a shuttling shielding substance that passes seen between the nucleus and the cytoplasm and the receiver nucleus. Whenever the levels of the shuttle were high, the GFP protein expression is shown both by the sender and receiver nucleus. The recipient nucleus will not be left without any schlepping protein. Thus, the donor nucleus can only be used.
No because it still moves along and stays on track
