Utility of CRISPR-Cas9 in genome editing lies in the error rate of DNA repair

Originally used in defending bacterial cells from attacks by viruses, clustered regularly interspersed short palindromic repeats (CRISPR) has been modified and utilized in editing single bases in DNA in a process known as genome editing. 466 more words

Transcriptomic resilience of the Montipora digitata holobiont to low pH

Ocean acidification is considered as one of the major threats for coral reefs at a global scale. Marine calcifying organisms, including stony corals, are expected to be the most affected by the predicted decrease of the surface water pH at the end of the century. 195 more words


Clustered regularly interspersed short palindromic repeats (CRISPR) bacterial defense system

Clustered regularly interspersed short palindromic repeats (CRISPR) is a bacterial defense system against foreign DNA or RNA carried by viruses, bacteriophages, or membrane vesicles. Specifically, nestled within the genome of the bacteria, CRISPR carries a memory of past infection of viruses and foreign DNA and RNA, and uses a Cas9 protein for destroying foreign DNA and RNA once they are recognized by specific guide RNA that constituted the molecular memory of past infections. 184 more words


Stopping the Transfer of Antibiotic Resistant Genes

By Meghan Bialt-DeCelie ‘19

The overuse of antibiotics is causing rapid increase in antibiotic resistant bacteria. Through a type IV secretion system, bacteria that aren’t killed by the antibiotics share their antibiotic resistant genes with other bacterial cells via bacterial conjugation. 344 more words


Degeneracy in protein sequence meant that evolutionary conservation occurred at the structure level

Given the importance of many proteins to the maintenance of cellular processes, the structures of the proteins are highly conserved independent of the sequence information at the amino acid and nucleotide level. 349 more words


About Amnesic Shellfish Poisoning

Amnesic shellfish poisoning, also known as ASP, is a rare disease caused by demoic acid that is usually found in razor clams, mussels and dungeness crab but it can be found in other shellfish as well. 426 more words
