Nucleic acids are a type of macromolecule used to store genetic information inside the cell. There are two main types of nucleic acids in cells, DNA and RNA.Answer and Explanation: The building blocks of DNA and RNA are nucleotides. These monomers are made of three parts, a sugar molecule,...
DNA和RNA有很大不同,DNA存储遗传信息,作为生命活动的最内核物质,如同操作系统内核一样,因而被称为系统流。依据中心法则得到的翻译得到RNA,RNA再翻译成蛋白质,蛋白质用于生命活动,所以RNA是随着生命活动不断转移和改变的,故被称为操作流。为了满足不同生命活动的需要,RNA变得比DNA灵活许多。但是DNA作为遗传物质的内核,...
