Answer:
La respuesta correcta es "micotoxina".
Explanation:
Las micotoxinas son sustancias químicas naturales que algunas especies de hongos sintetizan y son peligrosas porque pueden estar presentes en el moho de los alimentos. Las micotoxinas producen daños en el bazo y en el riñón, pero el hígado es el órgano que es mayormente afectado. Algunas micotoxinas producen aflatoxicosis, la cual puede llegar a causar la muerte.
When you start the PCR amplification reaction, you have a template which has sequences where the primers will anneal. The forward primer anneals in the sense strand and the reverse one in the complementary sequence (see attached figure).
After the first PCR cycle, two types of fragments are obtained. First those which come from tha 5'-3' sequence, that are 3'-5' and will anneal the reverse primer in the following cycle. This fragments have the correct 3' end, but the 5' includes part of the template that doesn't correspond to our target (see attached figure)
Second, those fragments that come from the 3'-5' sequence, that are 5'-3' and will anneal the forward primer. This fragments also have the correct 3' end, but the 5' includes part of the template that doesn't correspond to our target (see attached figure).
Now, during the second cycle, are produced the first fragments that have the precise length of the sequence that we want to amplify (see attached figure).
So, it's not until the third cycle that the reaction starts amplifying exactly the sequence of desired length.
Answer:
Eukaryotic in nature. They are higher classes of Eukaryotic organisms
Answer:
Explanation:
Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. ... Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
Answer: B)
Explanation:
The glycoprotein and glycolipid carbohydrate chain forms the hydrogen
bond with water molecules to help stabilize the membrane structure.
When it comes to glycoproteins and glycolipids and their bond we can say that their carbohydrate chain is forming a hydrogen bond with water molecules that are surrounding the cell and thus. In this case, they are helping in the stabilization of membrane structure. They are used as receptor molecules.
