The first step involves RNA polymerase, an enzyme that unwinds and unzips the double helix to access a protein-coding gene. The gene's DNA sequence is used as the template for transcribing an RNA copy of that gene, which the polymerase assembles from a chain of nucleotides.
26 Δεκ 2013 · Economizing on P use in RNA while maintaining growth rate and yield, radiation and water use efficiency and resistance to biophages, requires investigation, and remediation, of the following possible causes of “over-provision” of RNA.
10 Ιουλ 2013 · Complex processing of multicistronic transcripts, control of mRNA translation and stability, RNA editing, and intron splicing are all RNA metabolic processes that contribute to photosynthetic gene expression in chloroplasts (Stern et al. 2010; Barkan 2011).
During photosynthesis, energy from sunlight is harvested and used to drive the synthesis of glucose from CO2 and H2O. By converting the energy of sunlight to a usable form of potential chemical energy, photosynthesis is the ultimate source of metabolic energy for all biological systems.
Photosynthesis is a multi-step process that requires specific wavelengths of visible sunlight, carbon dioxide (which is low in energy), and water as substrates . After the process is complete, it releases oxygen and produces glyceraldehyde-3-phosphate (G3P), as well as simple carbohydrate molecules (high in energy) that can then be converted ...
28 Αυγ 2019 · Transient gene-body condensates contain phosphorylated Pol II enzymes, nascent RNA, elongation factors, RNA processing factors and elongation-specific co-activators.
Bacterial sRNAs are involved in processes ranging from virulence to the transition from growth to the stationary phase, which occurs when a bacterium encounters a situation such as nutrient ...
