more nucleotides are added to the mRNA, thereby forming a progressively longer chain of nucleotides (Figure 2). This process is called elongation. Three of the four nitrogenous bases that make up ...

The most common mammalian mRNA modification currently known is the methylation of nitrogen at position 6 in the adenosine base of mRNA. This modification is known as N6-methyladenosine (m 6 A ...

Each ribonucleotide base consists of a ribose sugar, a phosphate group, and a nitrogenous base ... messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). Although some RNA molecules ...

This discovery, along with the identification of other nitrogenous bases, laid the foundation for our understanding ... such as coding for proteins (mRNA), transferring amino acids (tRNA), and ...
