95K Understand cell division. Learn about DNA packaging, levels of DNA packaging, chromosome condensation, karyograms, histone modification, and chromatin packing. Related to this QuestionWhat is DNA packaging?
Transcription initiation is a major regulatory step in eukaryotic gene expression. It involves the assembly of general transcription factors and RNA polymerase II into a functional pre-initiation complex at core promoters. The degree of chromatin compaction controls the accessibility of the transcription ...
d. DNA is used as a template to Which of the following occurs outside of the nucleus in eukaryotic cells? a. chromatin packing b. mRNA processing c. transcriptional control d. translational control e. posttranscriptional control What are the steps an...
The human immunodeficiency virus type 1 (HIV-1) trans-activator of transcription protein Tat is an important factor in viral pathogenesis. In addition to its function as the key trans-activator of viral transcription, Tat is also secreted by the infected cell and taken up by neighboring cells w...
The high nuclear ATP concentrations may be necessary to promote the solubilization of proteins and chromatin within nuclei. Nuclear ATP appears to be uniformly distributed in cancer cells [13]. As ~100 μM ATP is sufficient for ATP-driven enzymology, its role as a hydrotrope provides a function...
