A prokaryotic cell expressing a gene of interest and comprising at least two copies of said gene on the chromosome. The copies are transcribed in different directions thereby avoiding homologous cross out. The DNA-segment between the two copies does not comprise any information essential for cell ...
Horizontal gene transfer, the exchange of genetic material through means other than reproduction, is a fundamental force in prokaryotic genome evolution. Genomic persistence of horizontally transferred genes has been shown to be influenced by both ecological and evolutionary factors. However, there is lim...
What is the function of a nucleus in an amoeba? How can prokaryotic cells be smaller than eukaryotic cells and still carry on all the functions of life? What is the function of an amoeba cell? Which organelles do eukaryotic cells have that prokaryotic cells do not have?
proteins, with a greater variety of structures than nucleic acids, took over the catalytic functions. As described in the previous section, the absence or presence of a nucleus — and indeed, of all membrane-bound organelles — is important enough to be a defining feature by which cells are ...
Carbohydrate involvement in the association of a prokaryotic cell with Trichomonas vaginalis and Tritrichomonas foetus 来自 掌桥科研 喜欢 0 阅读量: 30 作者:M Benchimol,WD Souza 摘要: Previous studies have shown that Trichomonas vaginalis are capable of ingesting bacteria. This observation was confirmed...
Specificity for DNA-containing methylated cytosines is a defining feature of EcMcrB (8, 9, 10, 11, 12, 13). Because TgΔ185 shares little sequence homology with the EcMcrB DNA-binding domain (EcΔ155; Fig. 2B), we first asked whether it could bind 5-methylcytosine (m5C) modified DNA...

Klebsiella pneumoniae is a major bacterial and opportunistic human pathogen, increasingly recognized as a healthcare burden globally. The convergence of resistance and virulence in K. pneumoniae strains has led to the formation of hypervirulent and multi
