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>.

What occurs after sunlight is absorbed by a chloroplast?
OLga [1]

Answer:

B

Explanation:

A cannot be true as photosynthesis requires carbon dioxide and water and uses light energy to break bonds and form oxygen and glucose

C cannot be true as chloroplasts contain chlorophyll which gives the cell its green colour by not absorbing green wavelengths of white light

D is not right as I do not believe photosynthesis is a basic function

Which source should be avoided when conducting scientific research?
Dennis_Churaev [7]
When we're doing scientific research, we should definitely be avoiding any sources which aren't scientific by nature. This means we should avoid sources which haven't been peer reviewed by fellow authors of a similar field. With this, we avoid using literature of questionable quality.
