Explain the different types of secondary metabolites, listing
the major chemical group types and some examples of their roles
Explain, using examples, why secondary compounds are important
to plant long-term survival even if they are not involved in
primary metabolic processes.
Discuss, using detailed examples, whether plants are really
‘helpless sessile organisms’... or not?
Explain the detailed steps and components of the process of
plant responses to a viral, bacterial or fungal pathogen involving
the hypersensitive response and that leads...

DNA EXTRACTION & PURITY PROTOCOL
Add a small piece of peeled banana (2-3 cm) and 12mL
extraction buffer (NaCl & Sodium Citrate) into the beaker.
This buffer contains salts necessary for the precipitation of
the DNA. The ions in the solution make it more polar facilitating
the dissolving of the DNA.
Add 3mL detergent into the beaker. This will break
open the cells and dissolve the DNA. Detergent breaks up the lipids
of the plasma and nuclear membranes
Questions:

1. What is monospermy? What is its purpose?
2. The secondary oocyte has how many chromosomes?
3. What is the corona radiata?
4. What is the zona pellucida?
5. What is a pronulecus?
Experiment 2: Using the Secondary Standard to Determine the
Concentration of an Acid
1. In an Erlenmeyer flask, add 25 mL of Unknown
#1 concentration of acetic acid
(CH3COOH) and 2 drops
of phenolphthalein indicator.
2. Coarse Titration:
(a) Take a burette from the Containers shelf
and place it on the workbench. Fill the burette
with 50 mL of the standardized sodium hydroxide
solution. Record the initial burette reading.
Place the Erlenmeyer flaskon the lower half of the
burette.
(b)...

Prove that 1^3 + 2^3 + · · · + n^3 = (1 + 2 + · · · + n)^2 for
every n ∈ N. That is, the sum of the first n perfect cubes is the
square of the sum of the first n natural numbers. (As a student, I
found it very surprising that the sum of the first n perfect cubes
was always a perfect square at all.)
