Summary Introduction
The presence of outer membrane in a gram-negative bacteria provides only a modest strength to the cell. However, it plays a potential role in protecting the cytoplasmic membrane from several agents like lipophilic antibiotics and various substances harmful to the membrane. In addition to protein and phospholipid, it also comprises of polysaccharide. The polysaccharide and lipid molecules connect with each other to form a complex. Thus, the outer membrane is also referred to as the lipopolysaccharide layer (LPS).

8. Transcription and Translation Practice: (Video 10-1 and 10-2)
A. Below is the sense strand of a DNA gene. Using the sense strand, create the antisense
DNA strand and label the 5' and 3' ends.
B. Use the antisense strand that you create in part A as a template to create the mRNA
transcript of the gene and label the 5' and 3' ends.
C. Translate the mRNA you produced in part B into the polypeptide sequence making sure
to follow all the rules of translation.

What is the structure and function of Eukaryotic cells, including their organelles? How are Eukaryotic cells different than Prokaryotic cells, in terms of evolution which form of the cell might have came first? How do Eukaryotic cells become malignant (cancerous)?
What are the roles of DNA and proteins inside of the cell? What are the building blocks or molecular components of the DNA and proteins? How are proteins produced within the cell? What connection is there between DNA, proteins, and the cell cycle? What is the relationship between DNA, proteins, and Cancer?
