A part of an mRNA molecule with the following sequence is being read by a ribosome: 5'-UGC-GCA-3' (mRNA). The charged transfer R

NA molecules shown in the figure below (with their anticodons shown in the 3' to 5' direction) are available. Two of them can correctly match the mRNA so that a dipeptide can form:

mRNA codons determine which amino acid will be added to the growing polypeptidic chain. tRNA anticodons pair these codons and add the correct amino acid. <em>The </em><em>dipeptide</em><em> formed will be </em><em>Cysteine-Alanine</em><em>.</em>

------------------------------------------

Let us review a few points,

  • In protein synthesis, the ribosome reads mRNA in the 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 codon represents one amino acid used to build the protein.

  • 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.

  • The anticodon is a short sequence of bases that pairs with mRNA codons.

  • tRNA adds amino acids following the codons sequence in the mRNA molecule.

  • The protein grows from the amino terminus to the carboxy terminus.

  • Adenine forms pairs with Uracyl ⇒ A↔U
  • Guanine pairs with Cytosine ⇒ C↔G

In the exposed example,

→ mRNA     ⇒  codons   ⇒ 5'-UGC - GCA-3'

→ tRNA       ⇒ anticodons ⇒  ACG  CGU

→ proteins  ⇒ amino acids ⇒  Cys     Ala ⇒ Codon UGC codes for Cysteine

                                                                     ⇒Codon GCA codes for Alanine

So, for the given sequence of mRNA, tRNA anticodons are ACG and CGU. And the added amino acids are <em>Cysteine and Alanine</em>.

Goryan [66]

Answer:

In a general aspect, humid and warm air moves to lower latitudes or in altitude, losing heat and getting colder. Its humidity condenses and causes precipitation. Depending on the air movement there are different kinds of rain.  

Explanation:

At a global level, it occurs unequal warming of the atmosphere, which depends on many factors and varies with latitude. This occurs because solar radiation reaches the earth differently at different latitudes, resulting in big convective cells of atmospheric circulation: Hardley cell, Ferrel cell, and Polar cell.    

A convective cell is the movement of the humid air among different latitudes. Air moves from higher latitudes to lower latitudes, getting warm, getting less dense, and ascending. As the air gets higher in altitude, it´s density and pressure decrease, so the air tends to expand with elevation in response to the reduced pressure. Gases in expansion experiment adiabatic cooling, losing caloric energy as their molecules move getting farther away from each other. As the air gets higher, it gets colder, and hence, denser. The result is that descends again. Humidity gets denser and precipitates.

• Rain is controlled by temperature on the earth´s surface, atmospheric global air circulation, the position of the mountains and oceans, closure to the oceans.  

• There are different kinds of precipitations according to their origin.

<em>i. Convective precipitation: </em>These are the most typical ones. Air gets warmer and less dense, elevating in altitude with humidity. On the way, it starts to get colder, and the humidity condenses, resulting in precipitation. Depending o the degree of condensation, the precipitation might be in a liquid state (rain), semisolid-state (snow), or solid-state (hail).

<em>ii. Frontal Precipitations: </em>They occur when a polar front coming from higher latitudes collide with a warm front coming from lower latitudes, resulting in a strong rain. This is typical of grasslands or temperate forests (approximately 40 º latitude)

<em>iii. Orographic Precipitations:</em> They occur when humid wind ascends by a mountain range, causing its adiabatic cooling, condensing the humidity, and precipitating.

A client periodically has acute panic attacks. These attacks are unpredictable and have no apparent association with a specific
Arisa [49]

Answer:B

Explanation:

Acute panic attacks are usually extreme period of fear and includes fast heartbeat rate, sweating and low breath. They are usually caused by nothing in particular and studies says it is hereditary.

The palpitation is a result of increased heart rate in which the heart beats faster.

The decreased respiratory rate causes the shortness of breath when this usually happens.
