What is epigenetic regulation of gene expression? What does it mean when we refer to regulation of gene expression? What are the fundamental differences between up-regulation and down-regulation of gene expression? What is the best definition of a gene?
My hope is that by pointing to our areas of ignorance, more systematic research will be undertaken, resulting in some clear answers about gene regulation in seeds.doi:10.1007/978-1-4615-6817-9_14M. L. CrouchSpringer USCrouch, M.L. (1987) Regulation of gene expression during seed ...
Fig. 1. Post-transcriptional control of gene expression. It comprises a complex regulatory network that contributes to cell-type and organism specific gene expression patterns. The pre-mRNA has to go through some modifications to become a mature mRNA molecule that can leave the nucleus an...
Metabolic regulation in mammals is the means by which mammals deliver energy as required for life, and sometimes involves the regulation of gene expression at the molecular level. Regulation of gene expression is a very general mechanism providing much of the metabolic regulation and physiologically re...
As well as evaluating overall transcriptome differences among sub-types, we evaluate the disease specificity of whole blood eQTL effects in order to infer what fraction of risk can be attributed to differences in genetic regulation of gene expression....
Explain the regulation of gene expression in bacteria in a/an: (a) inducible operon (b) repressible operon. Select the correct answer. What is the most common form of gene expression regulation in both bacteria and eukaryotes? a. transcriptional - level control b. constitutive - level ...
MicroRNAs (miRNAs) — approximately 21-nucleotide-long, genome-encoded RNAs — have emerged as key regulators of gene expression in eukaryotes. miRNAs represent just one class of small RNA regulators, the others being small interfering RNAs (siRNAs) and PIWI-associated RNAs (piRNAs), all of which...
Theoretically, in anabolic situations, the increase of gene expression of G6PD and 6-phosphogluconate dehydrogenase can induce a rise in the production of NADPH, which would cause the immediate inhibition of the enzyme and a drastic flow reduction. However, increasing the flow through oxidative phase...
