A bacterial reproduction where genetic material is transferred from one cell to another cell that is donor and recipient cell. This process of conjugation was discovered by Lederberg and Tatum, in the single strain of E.coli. It is a one-way process where the transfer of genetic material ...
17K Escherichis coli O157:H7 is one of the most dangerous types of E. coli infections, causing severe symptoms in humans and sometimes resulting in hemolytic uremic syndrome. Learn what distinguishes this serotype of E. coli, the diseases it causes, an...
Answer the following questions based on Meselson and Stahl's experiment of E. coli : (a) Write the name of the chemical substance used as the only source of nitrogen in the experiment. (b) Why did they allow the synthesis of the light and the heavy DNA molecules in the organism ?
Chlorogenic acid is condensed from the carboxyl group of caffeic acid and the hydroxyl group of quinic acid to depsilic acid. It is a phenylpropanoid substance synthesized by plant cells through the shikimic acid pathway. There are esters in its molecular structure bonds, unsaturated double bonds, ...
More aggressive surgical approaches have recently emerged, pushing the boundaries of PHC resectability at the cost of a higher morbidity. As such, adequate preoperative preparation (i.e., biliary drainage, venous embolization) is now regarded as a critical issue to increase the number of patients ...
Asia is the biggest producer of duck meat and eggs [1], and China is the main producer [2]. Genetic improvement programs for meat-type ducks have success- fully enhanced their productive performance. In particular, Pekin ducks are well known as the main meat-type duck and they have been ...
Alzheimer’s disease (AD), the most common cause of dementia, results in a sustained decline in cognition. There are currently few effective disease modifying therapies for AD, but insights into the mechanisms that mediate the onset and progression of di
Aside from the nine accessory proteins (ORFs), one-third of the genome contains four structural proteins: spikes (S), envelopes (E), membranes (M), and nucleocapsids (N), the latter of which is required for SARS-CoV entry into host cells (see in Schema 3). Even though SARS-CoV-2 ...
