The benzene molecule has the molecular formula C6H6
.
Sometimes it is represented as a molecule with three doble bonds and three single bonds. But that does not count for the fact that experimentally all the bonds are equal: same length and same strength.
The six carbon bonds are equal because there is not preference for the valence electrons to attach to one or othe neighbor carbon, so at the electrons delocalize inside the molecules and form a uniform cloud around the six carbon atoms.
This is the effect named resonance and thas is why the molecule of benzene instead of being represented with some three single bonds and three doble bonds is represented with a circle (a ring) inside the molecule which represents an intermediate kind of bond shares by all the carbon atoms.
This structure was discovered (literally dreames as some texts tell) by Kekulé.
Explanation:
Wobble Hypothesis given by Francis Harry Compton Crick states that 3rd base of mRNA codon can base pair with 1st base of a tRNA anticodon undergoing non-Watson-Crick.
The first 2 bases of the mRNA codon form Hydrogen bonds with the corresponding bases on tRNA anticodon in Watson-Crick manner. Through this, they only form the base pairs with the complimentary bases. However, formation of the Hydrogen bonds between 3rd base on codon and 1st base on anticodon can occur potentially in non-Watson-Crick manner.
<u>Thus, the Wobble Hypothesis explains that why the multiple codons can code for single amino acid.</u>
Answer:
B
Explanation:
it uses the process of the light reaction stage and Calvin cycle to trap sunlight in the day and make food at night
Answer:
Zn + CuSO4 —> ZnSO4 + Cu
Explanation:
Zn is higher than Cu in electrochemical series and so will displaces Cu in solution according to the equation:
Zn + CuSO4 —> ZnSO4 + Cu
