Draw several non essential and essential structures of eukaryotes and explain their functions name?
Diagram the process of the lytic and lysogenic replication?
what are some non essential structures that can contribute to a microbes potential to cause disease?
Homework Answers
1) Eukaryotic cell are defined as cells containing organised nucleus and membrane bound organelles .Most essential structure of it are a)Nucleus b) Mitochondria c)Chloroplast. Nonessential are: a) Golgi apparatus b ) Ribosomes c) Lysosome.
A) Nucleus - It is the main double membrane structure containing genetic information. Functions - It stores genetic information necessary for development and reproduction. Also contain information for protein synthesis and cellular functions.
B) Mitochondria- They are membrane bound and known as power
house of the cell .Functions - They produce energy (ATP). Helps in
regulating cell metabolism .Contain own DNA and RNA for protein
synthesis.
C) Golgi apparatus- It acts an important site for packaging
material within cell, for formation of glycolipids and
glycoprotein.
D) Endoplasmic reticulum : Have smooth Endoplasmic reticulum and
rough Endoplasmic reticulum . Functions: SER is involved in lipid
synthesis and RER is involved in protein synthesis, also in
transporting it in Golgi apparatus in vesicles.
E) Ribosomes - Known as protein synthesis .Functions as site of
protein synthesis and polypeptides.
2) Process of lytic and lysogenic replication : In lytic cell viral DNA exists as separate free floating molecule within bacterial cell different from host bacterial DNA .
In lysogenic ,viral DNA is located within host .

The marketing process does not take place automatically. It requires that certain marketing functions or activities be performed by various marketing institutions - and by consumers themselves. The following eight functions are essential to the marketing of all goods: buying, selling, transporting, storing, grading, financing, risk taking, and market information. No matter how simple or complex the marketing process is, these functions must be performed. Some functions may be performed several times to facilitate the marketing of a given product,...

For the following questions answer with as much detail as possible. If a metabolic pathway is involved draw a name all molecular structures and name all enzymes. Indicate cell type and location within the cell as well as any transport mechanisms. Since the fatty acid pathways are serpentine, show one pass through the sequence and then you may simply state how many times a sequence is repeated until a new reaction is needed. If asked to synthesize a fatty acid,...
