Translation requires some specialized equipment. Just as you wouldn't go to play tennis without your racket and ball, so a cell couldn't translate an mRNA into a protein without two pieces of molecular gear: ribosomes and tRNAs.<span>Ribosomes provide a structure in which translation can take place. They also catalyze the reaction that links amino acids to make a new protein.</span><span>tRNAs (transfer RNAs) carry amino acids to the ribosome. They act as "bridges," matching a codon in an mRNA with the amino acid it codes for.</span>Here, we’ll take a closer look at ribosomes and tRNAs. If you're not yet familiar with RNA (which stands for ribonucleic acid), I highly recommend checking out the nucleic acids section first so you can get the most out of this article!Ribosomes: Where the translation happensTranslation takes place inside structures called ribosomes, which are made of RNA and protein. Ribosomes organize translation and catalyze the reaction that joins amino acids to make a protein chain.
<span>Pacinian corpuscles are rapidly adapting mechanoreceptors so they respond only at the onset and offset of the stimulus. The Pacinian corpuscle has a single afferent nerve fiber. Its end is covered by a sensitive receptor membrane whose sodium channels will open when the membrane is deformed in any way. Pressure thus causes sodium to enter the neuron and create a generator potential. If this potential reaches a certain threshold nerve impulses are formed. This impulse is now transferred along the axon with the use of sodium channels and sodium/potassium pumps in the axon membrane. The magnitude of the stimulus is encoded in the frequency of impulses generated in the neuron. So the more massive or rapid the deformation of a single corpuscle, the higher the frequency of nerve impulses generated in its neuron.</span>
Answer:
The Greeks believed in the geocentric model of the universe.
According to this model, the Earth was present in the center whereas the Sun, moon, other planets etc revolved around it. According to Plato, the Earth was spherical in shape and it did not move. Greek philosophers, such as Aristotle and Plato, believed the Earth to be the center of the universe. All other heavenly bodies orbited around the Earth according to the Greek philosophers.
<h2>X-Ray diffraction</h2>
Explanation:
- x-ray diffraction and the macroscopic shape of crystals.
- X-ray diffraction is a nondestructive method generally utilized for the portrayal of smaller scale crystalline materials. The strategy has been generally applied for stage distinguishing proof, quantitative investigation and the assurance of structural flaws. Lately, applications have been stretched out to new territories, for example, the assurance of reasonably complex gem structures and the extraction of three-dimensional microstructural properties. This is the outcome of the higher goals of current diffractometers, the coming of high-power X-ray sources and the advancement of line-profile displaying ways to deal with conquer the line cover issue emerging from the one-dimensional information contained in a powder diffraction design.
