Concept explainers
(a)
Interpretation:
The mRNA sequence formed from DNA template
Concept Introduction:
DNA is a molecule that is stranded with two polynucleotides into a double helix structure. The two polynucleotide strands are placed antiparallel to each other. It means that one strand starts from
In transcription, DNA strand separates and mRNA with DNA template is formed by the catalyzation of RNA polymerase. The mRNA molecule formed has base pairs opposite to DNA template.
RNA does not contain thymine base instead it has uracil base. Therefore, in this purine base adenine (A) is held with pyrimidine base uracil (U) by two hydrogen bonds. Whereas purine base guanine (G) is held with pyrimidine base cytosine (C) by three hydrogen bonds. These base pairs are denoted as

- Nonearrow_forward3. A molecular form of "dicarbon", C2, can be generated in gas phase. Its bond dissociation energy has been determined at 599 kJ/mol. Use molecular orbital theory to explain why energy of dissociation for C₂+ is 513 kJ/mol, and that for C2² is 818 kJ/mol.

Assign the following molecules to proper point groups: Pyridine N 1,3,5-triazine N Narrow_forward7. a) Under normal conditions (room temperature & atmospheric pressure) potassium assumes bcc lattice. Atomic radius for 12-coordinate K atom is listed as 235 pm. What is the radius of potassium atom under normal conditions? (3 points) b) Titanium metal crystallyzes in hcp lattice. Under proper conditions nitrogen can be absorbed into the lattice of titanium resulting in an alloy of stoichiometry TiNo.2. Is this compound likely to be a substitutional or an interstitial alloy?
