To answer: Why physicians has substituted trimethoprim and sulfamethoxazole for tetracycline in the treatment of children and pregnant women infected with Brucella . Introduction: Brucella causes a highly contagious disease called as brucellosis. The bacteria are transmitted from animals to humans by ingestion. In an animal host, Brucella lives as an intracellular parasite in organs such as uterus and placenta.

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

Students have asked these similar questions

a) Find a nitrogen base. What carbon is the base attached to? b) What two nitrogenous bases are held together by 2 hydrogen bonds? c)What two nitrogenous bases are held together by 3 hydrogen bonds?

You will be building a double-stranded DNA molecule, representing a short (20 base) sequence that could be found in a chromosome. It will have a 3' --> 5' strand and a 5' --> 3' strand. Use two full 12-base-pair DNA models. a) Upload a photo of a model once the first 6 nucleotides have been inserted to base pair with the two parent strands. b)Upload a photo of DNA polymerase I and Ligase in "action" removing the RNA primer nucleotides and making new phosphodiester bonds. c)Upload a photo of the final two DNA strands, after Termination, identifying the parent and daughter strands of each.

Write down the 12 base-pairs (ex A-T or G-C) contained in the two models you will us from top to bottom below Model 1 bp: Model 2 bp:
