Under these conditions, RNA has the ability to split without adding a water molecule. The end of the RNA strand remains water ...
Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine (G), and uracil (U). RNA is often compared ...
See how one RNA sequence can exist in nearly 40,000 different ... an OH group at the 3′ end of the exon attacks the phosphodiester bond at the 3′ splice site. The adjoining exons are ...
But real lightning would have struck infrequently—and mostly in open ocean, where organic compounds would have quickly ...
Ribosomal RNA (rRNA) is a component of the ribosomes, the cellular machinery responsible for protein synthesis. rRNA molecules, along with ribosomal proteins, form the structure of the ribosomes and ...
The chemical structure of uracil, showing its single-ring pyrimidine structure. Uracil forms hydrogen bonds with adenine in RNA, contributing to the molecule's structure and function. (Image: Public ...
Cells express their genes by converting the genetic message into protein. This process of protein synthesis occurs in two stages - transcription and translation. When a gene is to be expressed ...
