sequencing is figuring out the order of nucleotides, or bases, in a genome. News basically means any information regarding a particular thing. So there are many topics that can create news. They can be of different types for example, DNA news, RNA news, sequencing news, protein news, etc. these news can include information such as what is that topic about, the basic technology involved and the uses.
