RNA is similar to DNA but contains uracil instead of thymine (T) and has a single-stranded structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding nucleobases ...

When a gene is to be expressed, the base sequence of DNA is copied or transcribed into mRNA (messenger RNA). This process takes place in the nucleus and occurs in a series of stages. The two ...
