what do the different bands in the same lane of an agarose gel represent?
Different bands obtained when the plasmid DNA is run on agarose gel is because of the fact that different conformations of the DNA have different extend of friction with agarose gel while migration.
What type of plasmids are present?Plasmids generally exist in 3 conformations: super coiled, open circular and linear. In-vivo, plasmid DNA is a tightly super coiled circle to enable it to fit inside the cell. In the laboratory, when we extract plasmid , most of the DNA will remain super coiled, but a certain amount will be in open circular and linear conformations. The open circular form of plasmid exist due to the break in only one of the strands, the DNA will exist as circular. The break will allow rotation around the phosphodiester back bone of DNA due to which super coils will be released, thus creating open circular DNA. The plasmid exists in the linear form when there is a cut in the circular DNA.

the pancreas produces a special hormone, which stimulates the absorbtion of blood sugar. this hormone is called
Glucagon. Glucagon is a hormone that regulates blood glucose levels in conjunction with other hormones and physiological processes.
It is an essential element that maintains the body's blood glucose levels since it originates from beta cells, which secrete insulin, and alpha cells, which are present in the pancreas. Insulin and glucagon, which control blood glucose levels, and somatostatin, which inhibits the production of insulin and glucagon, are the two primary hormones secreted by the endocrine gland in the pancreas. The pancreas controls blood glucose levels by producing a variety of hormones, most notably glucagon and insulin, and keeping them within a relatively small range of 4-6 mM. The regulated and opposing actions of glucagon and insulin, often known as glucose homeostasis, enable this preservation.

Antigen-specific T cells and B cells are encouraged to proliferate by the process of clonal selection.
Absence of any memory population leads to a full-fledged spontaneous proliferation in which T cells with higher affinity to MHC-self-antigens (and commensal antigens) are triggered for proliferation.In humoral immunity, antigens bind to antibodies, activating B cells to produce plasma cells and memory B cells. Antigens then recognise them so they can be eliminated. The antigen is swallowed by macrophages during cell-mediated immunity, which then exposes it on their surface.

Jack and Diane had worked hard to make it through college at the University of Houston. Both had taken out student loans and worked full-time to make it through. The hard work paid off when Jack got his first electrical engineering job at a large computer company in Houston making $35,000 a year. Diane graduated with a degree in child development and started a little daycare center in their new suburban home outside Houston.
Things were going so well that they decided to make an addition to the family, and luckily enough, nine months later, a bouncing baby boy arrived. Danny seemed to be a perfectly healthy baby boy. When Danny started to walk, he fell a lot, as most children do. On one occasion Danny hit his head on the coffee table and cut himself above his right eye. As concerned parents, Jack and Diane took Danny to their local pediatrician to see if he needed stitches.
As they were driving to the doctor, Diane commented that the bleeding would not stop. When the pediatrician began sewing up the eye, he knew that there was more to the cut than just a simple laceration. The doctor asked the concerned parents if Danny was a hemophiliac. To this point, they had never had any reason to suspect that their little boy had any problems with blood clotting. The doctor took some blood and sent it to the lab to be analyzed. Their fears were confirmed--Danny was a hemophiliac.
Hemophilia refers to a group of bleeding disorders in which it takes a long time for the blood to clot. In severe cases, serious bleeding may occur without any cause and internal bleeding may occur anywhere.
Hemophilia is an X-linked recessive characteristic that usually occurs in males. If a mother is a carrier of the recessive gene there is a 25% chance she will have a child who is a hemophiliac. If females are born with hemophilia they are certain to have problems during puberty. To treat this problem, victims are given transfusions of Factor VIII, which is one of the platelet chemicals that healthy people produce to clot blood. The cost of Factor VIII transfusions can run up to $80,000 a year per patient. Luckily for Jack and Diane, they had insurance through his company. The insurance paid 90% of the bills so that left $8,000 to be paid by Jack and Diane. This put a small stress on their marriage. However, they decided to have another child, even though they knew there was a 25% chance their next child could be a hemophiliac also.

Explain how ATP and creatine phosphate function in skeletal muscle fiber contraction.
In a muscle at rest, extra ATP converts creatine into ADP and creatine phosphate by transferring its energy. This serves as a source of energy that may be swiftly drawn upon to produce further ATP.
Creatine phosphate transfers its phosphate back to ADP to form ATP and creatine when the muscle begins to contract and needs energy.
ATP provides the necessary energy for muscular contraction. The active-transport Ca++ pumps in the SR are powered by ATP, which also plays a direct role in the cross-bridge cycle. Without enough ATP, muscle contraction is impossible. Only a few seconds' worth of muscular contractions can be powered by the tiny quantity of ATP that is stored in muscle. To enable persistent contraction, ATP must be rapidly created and supplied as it is depleted.
