The number 6 is seamounts
Leucine (Leu) and essential amino acid (Ile) are unit isomers of each other with terribly similar structures and properties. They each have Hydrophobic facet chains of an analogous size. As each residues area unit H'phobic, they're going to attempt to bury themselves within the interior of the macro-molecule to minimize disruption to the water H-bonding network, driven by the Hydrophobic interaction. thus in wild kind and mutant protein, each Leu and Ile are going to be in very similar position. Because of them being isomers, they need similar facet chain geometries thus there will not be any issue with steric constraints, in order that they can each occupy a awfully similar area within the hydrophobic core of the macro-molecule.
As within the wild sort catalyst, Leu is within the situation, it's possibly concerned within the mechanism of the catalyst. but a Leu mutation can conserve the properties of the residue that are necessary for chemical action. they're fairly nonreactive facet chains, thus are possibly concerned in binding of the substrate through the H'phobic interaction. thus the mutation might slightly decrease the affinity of the catalyst for the substrate, and reduce the speed of chemical action somewhat.
Answer:
Pros of HeLa cells:
- HeLa cells are immortal ,easy to maintain and can be kept alive.
- HeLa cells easily contaminate cell lines and thus can be incorporated easily into target tissues.
Cons of HeLa cell:
- The HeLa cells can easily contaminate cell lines and a lack of regular monitoring leads to unwanted contamination of cell lines resulting in wastage.
Explanation:
HeLa cells are immortal cells that are used in scientific and medical research. These were obtained from Henrietta Lacks , a cervical cancer patient. These cells are well known for their immortality, rapid growth and high contamination rate. These were unique cancerous cells that kept on dividing and remained alive easily.
Your answer should be A: Eukaryotes are usually much larger than prokaryotes.
Eukaryotes can be described as complex, large structured cells, while prokaryotes are simpler, smaller calls.
Hope this helps!
Answer:
No, it isn't
Explanation:
An invasive species is characterized by an organism's appearance in an area it is not a native of, with a high capacity of reproduction that will cause it to be a threat to native species in that area. A species of organism is tagged "invasive" if it is foreign to a region/location and possess a high reproductive rate that spreads fast and causes harm to other species.
Based on the analogy given in this question about the escape of a rattlesnake from a zoo, it cannot be ascertained that it is an example of invasive species. This is because rattlesnakes may be native to that area and possess a zero threat level to the environment in terms of high spreading rate.
