Structure-guided discovery of anti-CRISPR and anti-phage defense proteins
Identification of putative anti-crispr proteins using structural features To identify Acrs in phage genomes, we began by retrieving ~66.5 million proteins from Integrated Microbial Genomes Virus database (IMG/VR)37. We excluded large proteins because over 90% of known Acrs contain less than 200 amino acids38 (Fig. 1A, Supplementary Data 1). To reduce computational…

[Solved] Which of the following dsDNA fragments would have the highest – Foundations in Molecular Biology and Genetics FW (Mbg2040)
Answer The melting temperature (Tm) of a DNA fragment is determined by its nucleotide composition. Specifically, DNA fragments with a higher proportion of Guanine (G) and Cytosine (C) base pairs will have a higher Tm because G-C base pairs form three hydrogen bonds, compared to the two formed by Adenine…
