Describe the functions of plasmids and transposons.



Plasmids:
Conjugative plasmid: carries the genes for sex pili and transfer of the plasmid
Dissimilation plasmid: encode enzymes for catabolism of unusual compounds
R factors: encode antibiotic resistance

Transposons:
segments of DNA that can move fro one region of DNA to another; contain insertion sequences for cutting and resealing DNA (transposase); complex transposons carry other genes

In any organization, employees rely on the grapevine, particularly during times of uncertainty. The grapevine is an unstructured and informal network founded on social relationships rather than organizational charts or job descriptions. Although early research identified several unique features of the grapevine, some of these features may be changing as the Internet plays an increasing role in grapevine communication.

Examine the age-structure diagrams of Sweden and Kenya below, and answer the following questions.   Compare and contrast the two age structure diagrams in terms of two population dynamics - birth rate and death rate. Restatement: Given two age-structure diagram, Sweden and Kenya for 2000, compare and contrast the diagram in terms of population dynamics.  Age structure diagrams are basically divided into three major age categories: 1) Prereproduction (0-15 years old) 2) Reproductive (16-45 years old) 3) Postreproduction (46 years old-death) Birth Rate Sweden  1) Population has nearly equal proportions of pre-reproductive and reproductive individuals. 2) Little growth over a long period of time will produce a population with about equal numbers of people in all age groups. 3) Children not required or necessary to support parents.  4) Availability and acceptance of birth control. Kenya 1) Population had pyramid-shaped age structu...
