As is customary, eukaryotic promoters are more complex. Eukaryotes have three types of RNAPs, resulting in three corresponding classes of promoters. RNAP I is responsible for transcribing rRNA and corresponds to class I promoters, consisting of a core promoter (-45 to +20) and upstream control elements (-180 to -107). Small […]

Transcription requires complete double-stranded DNA, but each transcription uses only one strand as a template, called the template strand, and the other strand is called the coding strand. The transcription process consists of three phases: initiation, elongation, and termination. The initiation phase includes the recognition of specific sites on the

If you are interested in gas chromatography but don’t know much about it, this article will introduce you to gas chromatography in detail. 1. What is gas chromatography? Gas chromatography, abbreviated as GC, is an analytical method for qualitatively and quantitatively analyzing the components of a mixture. It uses a

What are steroids? Steroids are a class of chemical substances with a steroidal structure that are required for biological activities in the human body. They are primarily secreted by the adrenal glands and gonads. Steroids are a class of organic compounds composed of four rings and a short chain. Steroids

What is Protein methylation? Protein methylation refers to the enzymatic transfer of a methyl group to a specific residue in a protein, typically lysine or arginine, histidine, cysteine, or asparagine. Protein methylation is a common modification. It is often listed alongside acetylation because both are common epigenetic modifications and often
