Let us, quickly get a glimpse of them:
Questions
About the World of Microbial
Q.1. What is the major difference between
gram positive and gram negative cell wall of the bacteria?
l
Gram positive: This cell wall consists of
multiple layers of peptidoglyclan, without a lipid outer membrane.
l
Gram negative: Here the cell wall has only
a few layers of peptidoglyclan along with an outer membrane that has multiple
lipid complexes.
Q.2. How does the bacteria and
eukaryotic cells differ from each other in terms of the genetic material?
l
The DNA in prokaryotic cells is generally
organized as a simple circular molecule that is placed in the nucleoid region
of cytoplasm.
l
Eukaryotic cells on the other end, have
their DNA divided in various chromosomes that are located in the nucleus. Also,
additional genetic material is found in some organelles like chloroplasts and
mitochondrion.
Questions
About Viruses and Cell Organelles
Q.3. Discuss the differences between lytic
and lysogenic cycles of viruses.
l
Lytic Cycle: Here the host bacterium is
destroyed that is, it undergoes lysis. It produces progeny phases and it cannot
be converted into lysogenic cycle.
l
Lysogenic Cycle: The bacterium and the
phage shares a symbiotic relationship, such that the host is not affected. Here
the DNA of the phage becomes a part of the bacterial chromosomes. If exposed to
certain chemicals and/or physical agents it can be converted into lytic cycle.
These agents may vary from UV rays to nitrogen mustard.
Q.4. List the nucleic acids that are found
in viruses.
l
Depending on the nucleic acid that a virus
carries it can be either a DNA virus or a RNA virus. Majorly viruses have RNA
genome. Single-stranded RNA viruses are found in plant viruses and
double-stranded DNA genomes are found in bacteriophages.
Questions
About Carbohydrates
Q.5. Distinguish the following in terms of
linkage.
l Starch
and Cellulose: In starch large number of glucose units are joined together by
glycosidic bonds. Cellulose consists of some several hundreds to nearly ten
thousand β(1→4) D linked
glucose units.
l Lactose and Maltose: Lactose is a disaccharide where one
glucose and galactose are bonded through β-1→4 linkage. Whereas, maltose is a
disaccharide which uses α (1→4) bond to join two glucose units.
Q.6. Give three
examples of monosaccharides.
l
Fructose, Glucose
(dextrose), and galactose.
Questions About Nucleic Acid
Q.7. Differentiate between
DNA-B helix and DNA-Z helix.
Geometry Attribute |
DNA-B Helix |
DNA-Z Helix |
Helix sense |
It is right-handed |
It is left-handed |
Repeating Unit |
1 bp |
2 bp |
Diameter |
20 Å |
18 Å |
Base per turn |
10.5 |
12 |
Rise base pair among axis |
0.332 nm |
0.38 nm |
Q.8. What are nucleoside and nucleotide?
l
Nucleoside= sugar+base. It contains a sugar
group and a base.
l
Nucleotide= sugar+base+phosphate. Through
phosphorylation of nucleoside by kinases produces nucleotides.
Questions
About Protein
Q.9. Name the techniques through which
protein quantification can be done.
l
There are various techniques through which
protein quantification can be done, this includes:
1) Bicinchoninic acid protein assay,
2) Bradford dye binding protein assay,
3) Colloidal gold protein assay,
4) Lowry protein assay, and
5) Ultraviolet absorption protein assay.
Questions
About TCA Cycle
Q.10 What is the cite for TCA cycle? Can it
take place in anaerobic system?
l
TCA cycle takes place in the matrix of the
mitochondrion.
No, TCA cycle can
never take place in anaerobic system. As there the pyruvate is converted into
ethanol or lactate. Therefore, it has to take place in an aerobic system.
Questions
About Urea cycle
Q.11. Calculate the APA equivalents
required for following synthesis:
l
1 molecule of glucose from 2 molecules of
lactate via gluconeogenesis,
The net reaction of gluconeogenesis will
be:
2 Lactate + 4 NADH + 4
ATP + 2 GTP = Pyruvate + 4 NAD + 4 ADP + 2GDP + 6 Pi
Thus, the total number
of ATP required is 18 (4 x3 + 4 + 2).
Questions
About Biochemical Manufacturing
Q.12. Discuss any 3 precautions to consider
while handling plant cells.
l
The dose of fungicides and antibiotics has
to be perfect in order to prevent any contamination.
l
Sterile conditions should be maintained.
This includes use of filtered air and glassware serialization.
l
For survival and proliferation of cells
optimal maintenance of physical factors is required like- pH level, humidity,
lighting, and temperature.
With these 12
questions answered, your Biochemical Engineering assignment writing will surely
be all sorted.
