Osmosis: In osmosis, water always moves from an area of higher water concentration to one of lower concentration. In the diagram shown, the solute cannot pass through the selectively permeable membrane, but the water can.
There are numerous ways through which we can reduce the smog problem like turning the engine of car off, not burning garbage in open.
<h3>What is smog and how come it be reduced?</h3>
- Whenever we go out in winters in the early morning we can see the eyes not able to see things far , because of the opaque weather and whitish too , called fog.
- Fog is completely different from smog and have different causes and effects also.
- Smog is the pollution cause in the nature due human activities majorly that reduces the air visibility.
- We can try to reduce smog by preventing burning garbage in open, by planting more and more trees.
- Nitrogen oxide is the main component of smog which is harmful to health.

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>.
