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>.

How are monosaccharides made from a disaccharide ?? And what’s the reaction called ?
Natalka [10]

Glucose, galactose, and fructose are monosaccharide isomers, which means they all have the same chemical formula but differ structurally and chemically. Disaccharides form when two monosaccharides undergo a dehydration reaction (a condensation reaction); they are held together by a covalent bond. (Lumen Learning to learn more, or to cite)
