Contaminated Media.





Contaminated Nutrient Agar Media.

 The media is contaminated because the media was 

 prepared in Open Place [ normal lab and with so many 

 people was in near of the media. when it was preparing  ] 

 not in Laminar flow air Cabinet.





Picture is taken by Shabab Mehebub from " Genetic engineering and Biotechnology Lab, East West University" 





Different Bacterial colony are seen in this Media. Different types of Bacteria are grown in this Media. Some fungi are also grown in this media. In this picture [ From left side ] you can see this. 
SO, THINK HOW MUCH MICROORGANISMS ARE IN CONTACT WITH US. THIS ARE NOTHING. YOU KNOW?? WE, HUMAN ARE CARRYING 3-6 pounds of BACTERIA. :D :) 
MICROORGANISMS ARE GOOD FRIEND OF US......

Editing of Human Embryo

                  Editing of Human Embryo What is CRISPR? Clustered regularly-interspaced short palindromic repeats   (abbreviated as   CRISPR , pronounced   crisper are segments of   prokaryotic   DNA   containing short repetitions of base sequences. Each repetition is followed by short segments of " spacer DNA " from previous exposures to a bacterial   virus   or   plasmid . How t o U se? By Editing Genome CRISPRs have been used to cut five to 62 genes at once: pig cells have been engineered to inactivate all 62 Porcine Endogenous Retrovirus  in the pig genome, which eliminated infection from the pig to human cells in culture. CRISPR's low cost compared to alternatives is widely seen as revolutionary. Selective engineered redirection of the CRISPR/Cas system was first demonstrated in 2012 in: ·      ...

Zika Virus Outbreak!

                                                            Z IK A Virus What is Zika Virus? Zika virus ( ZIKV) is a member of the   Flaviviridae   virus   family   and the   Flavivirus   genus. In humans, it initially causes a mild illness known as   Zika fever , Zika, or Zika disease, which since the 1950s has been known to occur within a narrow equatorial belt from Africa to Asia. In 2014, the virus spread eastward across the Pacific Ocean to   French Polynesia , then to   Easter Island   and in 2015 to Central America, the Caribbean, and South America, where the   Zika outbreak   has reached   pandemic   levels.
