What structure is most important in forming the tetrads?

Biology
1 answer:

Answer:

The correct answer will be option- synaptonemal complex.

Explanation:

The tetrad arrangement of the genetic material in an organism is mediated by a highly conserved structure known as the synaptonemal complex.  The synaptonemal complex is formed during the prophase I of the meiosis I which attaches the chromatin of the homologous chromosomes.

The synaptonemal complex is a proteinaceous structure which is formed by the two lateral ladders like elements with a central portion composed of the central element. The chromatin gets attached to the lateral elements while the central a portion bridge space between the two ladders thus help in the formation of the tetrad.

Thus, option- synaptonemal complex is the correct answer.

Answer:

Following are the answer to this question:

Explanation:

In option a:

There are many ways, which can be defined as follows:  

  • It keeping cells "qualified," use heat shock and handle ions like Ca and ice incubating.
  • It uses Micro-injection with DNA.  
  • It uses the biolistics or even the process of gene-gun.  

The stable cell charts indicate simple and definitive outcomes when their relationship to specific results. Moreover, relative to temporary cell lines, findings are more reliable and error-free. These lines also easily break and much less.

In option b:

Radio tests including linking tests could be used  

The Ligand Binding Assays is an analysis, that is based on the binding of ligands to antibodies, or other macromolecules. Its existence and distance of formed ligand-receptor complexes are defined using a system of measurement that is usually electrical or fluorescent.

In option c:

The method for measuring the levels of cell growth is accessible and the  Another way is to measure the metabolism within the same cell. So many color pigments were also accessible that can permeate an organism as well as react with some proteins as well as other factors, and that can effectively identify a color final product.  

Throughout relation to the amount of metabolism exercise, cell proliferation could be evaluated by researching one or even more cell markings. The BrdU limited liability assessment is a very well-published illustration.  

Its specific antibody can detect BrdU and high BrdUincorporations levels are linked to high levels of cell proliferation.  Command cell without DNA receptor growth hormone.

In option d:

The cell growth will stop after each use of RNA interference ( RNAi). The p007 formation as well as the effect on growth caused by the intrusion will be a goal. If development is delayed effectively, the theory will be tested successfully to a cell without any of the required DNA. The RNAi is the free cell

When a plant cell, such as one from a rose stem, is submerged in a very hypotonic solution, what is likely to occur?
kotykmax [81]

Solution:

When a plant cell, such as one from a rose stem, is submerged in a very hypotonic solution, then the cell will become turgid.

Thus this is the required answer.

frosja888 [35]

Answer:

An unconditioned response.

Explanation:

Pavlov was the process of studying salivation in dogs as a part of a research program on chewing and digestion. This is known as a normal reflex that is under personal choice or control and also called an unlearned evolutionary response.

In terms of Pavlov's analysis of learning, Pavlov built a device that would help to accurately measure the amount of saliva produced by dogs. In the case of Pavlov dogs, the food is called as the stimulus and salivation is called as a response.

Which one of the following choices best represents a short-term benefit of cardiorespiratory fitness?
Kobotan [32]
C - it increases stamina and reduces fatigue.

While stress and boredom reduction are also true, they are not cardiovascular benefits in this case. For that reason, answer C is the correct one. When one starts being physically active for a certain amount of time, increased stamina and reduced fatigue will follow.
