Answer:
The right order is
incomplete dominance ==> 2
polygenic inheritance ==> 3
codominance ==> 1
Many physical characters depend on many different factors, each of which is determined by different genes. This is called polygenic inheritance.
Codminance: The phenotype of each allele is expressed simultaneously in heterozygotes.
Incomplete Dominance: An intermediate phenotype is obtained between the two dominant alleles.
Answer:
C) Three hydrogen bonds will form with guanine.
Explanation:
Generally the DNA molecule is made up of Purines bases of Adenine and Guanine,and Pyrimidine of Cytosine and Guanine.However,RNA contains a different pyrimidine of Uracil.Thus the pairing is A-U am C-G.The uracil replaces Thymine.
The structure above is a Pyrimidine,because it is made up of single ring structure(an heterocylclic aromatic structure) compare to double structure of purines. Heterocyclic means it is ring form.Aromatic means it has resonance bonds which shift with the rings for stability.
It is also contains of two substitutes at position 4 of the ring structure (amineNH2) and at 2 which is the Keto group(=0).Therefore the structure is Cytosine.
In RNA structure the Cytosine pair with the three hydrogen bonds with guanine,while Adenine pair with Uracil.This ensures stability of the RNA structure.
