Which force is responsible for waves and surface currents?

Fynjy0 [20]

Ocean tides are caused by the gravitation of the Moon. Currents can be formed by the flow of tidal water around the continental plates, or by a difference in water temperature between large ocean areas. Surface waves are caused by the wind. Abnormal waves can be created by the tectonic movement of plates around and under the ocean floor (tsunamis). So as you can see, the answer is (C) Gravity

Which part of your brain is essential for receiving information that you are moving your legs?

stealth61 [152]

Motor coretex is essential for receiving information that you are moving your legs.

<h3>What is motor cortex?</h3>

The motor cortex's main job is to provide signals that control how the body moves. It is anterior to the central sulcus and a portion of the frontal lobe.
The primary motor cortex, premotor cortex, and supplementary motor area make up this region.
The motor cortex generates signals that are particular to movements and sends them to the muscles via spinal cord circuits and motoneurons to regulate motor behavior.
For the execution of movements to be precise, coordinated muscle activation patterns are required.

What are two specific examples of where this division occurs in nature?

romanna [79]

Answer:

There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells.

Explanation:

hope this helps you.

From a chemical view, how is an amino acid is being recognized by its specific aminoacyl tRNA synthetase?

hammer [34]

During translation, rRNA and tRNA read mRNA in 5´ to 3´ direction. According to the codons being readen, tRNA transfers the correct amino acids to build the polypeptide chain. A codon is a short sequence of three nucleotides that store the genetic information for the aminoacids´ assembly.

Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid through the action of the aminoacyl-tRNA synthase enzyme. The whole complex, amino acid + enzyme + tRNA is named aminoacyl-tRNA.

Each tRNA is recognized by a specific aminoacyl-tRNA synthase enzyme. The enzyme is also capable of recognizing a specific amino acid. Let us say, for instance, that tRNA is specific for phenylalanine. The molecule is attached to the enzyme that is specific for that tRNA(Phe). Then, when the enzyme and tRNA(Phe) are together, they get to find phenylalanine. The enzyme links the aminoacid to the RNA. Once the whole complex is formed, the tRNA gets to pair its anticodon with the mRNA codon. This is,

Recognition of enzyme and the specific tRNA(aa) ⇒ aa being aminoacid
Recognition of enzyme and the specific aminoacid
Linkage of the aminoacid to RNA by the enzyme action
Pairing of tRNA anticodon to mRNA codon.

Considering that there are twenty amino acids available, there are also twenty complexes of aminoacyl-tRNA, one for each amino acid. Each of the mRNA codons represents one of the 20 amino acids used to build the protein. Each amino acid can be codified by more than one codon. Of the total 64 codons, 61 codify amino acids, and one is a start codon. The left three codons are stopping translation points.

tRNA decodes genetic information from the nucleotidic sequence in the mRNA molecule and allows amino acids to align composing the new protein.

Once the new peptidic link joins, placing together the new amino acid to the growing peptidic chain, the binding between the amino acid and the tRNA molecule breaks. The tRNA is now free to join another amino acid and repeat the cycle.

In conclusion, a specific aminoacyl-tRNA synthase enzyme recognizes a tRNA, which is also specific for a certain amino acid. When together, the enzyme recognizes the amino acid and links it to the RNA. The whole complex is known as aminoacyl-tRNA. Once the tRNA is joined to its amino acid, it gets to pair a codon of mRNA to add that amino acid to the new synthesizing protein.
