Answer:

Proton

Explanation:

There are 3 types of particles in a nucleus of an atom.

  1. Protons (positively charged)
  2. Electrons (Negatively charged)
  3. Neutrons (Neutral)

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
iren [92.7K]

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>.

This food chain can be found in the coastal waters of Virginia which organisms in this food chain are herbivore
garik1379 [7]

The right answer is Damselfish

The damselfish is a species of herbivorous fish that contributes to a balance of marine plants by eating algae among corals, to prevent the proliferation of algae and to promote the growth of coral reefs. The parrotfish (Scaridae) or "coral cleaner" has the same similarity of the diet with the same equilibrium that the damselfish offers, but it can also feed on coral.
