How is RNA used in CRISPR and mRNA vaccines?

Why is RNA important in immunity? All organisms, from single-celled bacteria to blue whales, have a genome that’s made of deoxyribonucleic acid, or DNA. When it comes to viruses, many use single-stranded ribonucleic acid (RNA). However, certain species (such as rotavirus, which causes gastroenteritis) have a double-stranded RNA genome. The…

Introduction: The CRISPR-Cas system is a crucial defense system against foreign invaders, like bacteriophage, transposons, and plasmids in many prokaryotes. There are five genes present on it: tracr, Cas1, Crispr, Cas2, Cas9 on the CRISPR. The tracrRNA and the crRNA have a guiding function in the expression phase of the defense mechanism.

CROP-seq data analysis

CROP-seq data analysis 1 Hi, I am a new bie to single cell sequencing analysis. I have to analyze CROP-seq data, I am going through the following paper, www.nature.com/articles/nmeth.4177. I have to use cell ranger ( instead of DROP-seq software) as the first step to process single cell data.I wanted…
