How do somatic cells reproduce? Does mitosis produce somatic cells or gametes? Where is there no DNA replication between meiosis I and II? When a cell divides during mitosis do the two cells get smaller? How are somatic cells formed?
This process occurs in only a small proportion of cells. Although several studies have investigated the transcriptional changes that occur during sexual development and attempted to identify genes that may be involved, the molecular basis of sexual conversion has been elusive. Recent work has ...
The other outcome for the RNAP is to pass through the roadblock (Fig. 1). To do this, RNAP can simply take advantage of the spontaneous dissociation of the roadblock protein and escape a roadblock site before the protein can rebind to the DNA. Alternatively, RNAP may actively remove the...
Cellular senescence is a multifaceted process that arrests the proliferation of cells that are at risk of neoplastic transformation. Many stimuli elicit a senescence response. These include dysfunctional telomeres, DNA damage, the expression of certain oncogenes, perturbations to chromatin organization and...
Why do cells need messenger RNA? Where does RNA polymerase begin transcribing a gene into mRNA? Is ribosomal RNA made during transcription? How are RNA and DNA used to make proteins? How does an RNA virus replicate? What happens during RNA splicing?
There are three classes of antibiotics that kill mycoplasma when used at relatively low concentrations:tetracyclines, macrolides and quinolones. Tetracyclines and macrolides block protein synthesis by interfering with ribosome translation, whereas quinolones inhibit replication of mycoplasma DNA. ...
through psychometric scales. Future research should use subtler measures (e.g., Implicit Association Tests) to capture the concept’s subconscious nature. Third, although we test the origin-backfire effect in two real-world scandals and multiple manipulated transgressions, replication in different ...
The DNA uses the machinery of your own cell to reproduce new virus particles - particles that are released to invade more cells. A virus turns your own cells into mini-copy machines to replicate itself into a vast army.Viral infections include: Rabies, Chickenpox, influe...
DNA. Furthermore, if injecting Cas9 mRNA, translation to Cas9 protein must also occur, further delaying the editing process, thus resulting in a higher rate of mosaicism. It has been suggested that injection of the CRISPR/Cas9 RNP prior to the S-phase of DNA replication could reduce mosaicism...
centrifugation of cell extract on sucrose gradients, allowing for the separation of mRNAs that are associated with one ribosome (monosome) from those being translated by multiple ribosomes (polysome). Sucrose gradient fractionation facilitates qualitative analysis of the translation status of cells. ...
