RNA

Ribonucleic acid (RNA) is a molecule similar to DNA. Unlike DNA, RNA is single-stranded. An RNA strand has a backbone made of alternating sugar (ribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), uracil (U), cytosine (C), or guanine (G). Different types of RNA exist in the cell: messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). More recently, some small RNAs have been found to be involved in regulating gene expression.

DNA Sequence Editor Web App

Description: DNA Sequence Editor is a free web tool to analyze and edit your DNA sequence. Enter your DNA sequence and you can get the reverse, complementary or transcription sequence of your DNA. It can also translate your DNA sequence into possible amino acid sequences. It also help you to predict the DNA enzyme digestion result. Just select an enzyme from the list and you can get the size and sequence of each restricted DNA fragment. It is a useful web tool for molecular biology students and professionals. It is a great help for your molecular cloning work.
