WebBack in the 1970s, scientists thought that one gene coded for one mRNA, which in turn coded for one protein. This is largely true for bacteria and other single-celled life; however, for multicellular life one gene codes for one mRNA that can be spliced in different ways to create many different proteins. This is called alternative splicing. WebFeb 22, 2024 · The DNA of life on Earth naturally stores its information in just four key chemicals—guanine, cytosine, adenine and thymine, …
