Where does RNA editing occur in the cytoplasm of an animal cell? During protein synthesis, ___ occurs in the nucleus as a copy of DNA is made into mRNA, and ___ begins in the cytoplasm, when mRNA associates with a ribosome. How does splicing of pre-mRNA occur? What would happen if...
What is the monomer of DNA? How do they form DNA? How does DNA form a double helix? What happens when RNA polymerase malfunctions? What changes in entropy and free energy occur as nucleotides are linked together to form molecules of DNA?
R. (1995). The role of p53 in regulating genomic stability when DNA and RNA synthesis are inhibited. Trends Biochem. Sci. 20, 431-434.Chernova, O.B.; Chernov, M.V.; Agarwal, M.L.; Taylor, W.R.; Stark G.R. The role of p53 in regulating genomic stability when DNA and RNA ...
RNA extraction, cDNA synthesis, and reference plasmid cloning To analyze differential gene expression during develop- ment, samples were collected and RNA extracted as follows. Female beetles with haplotypes HT1, HT1*, and HT2 were paired with one male (HT2) each. Every 24 h, the laid ...
Late replicating regions, in which replication problems occur late in S-phase, are predestined for continuing replication in S/G2, and at under-replicated DNA replication continues even in mitosis. Mitotic DNA synthesis (MiDAS) is a conservative form of break-induced replication that works at ...
Deubiquitination is now understood to be as important as its partner ubiquitination for the maintenance of protein half-life, activity, and localization under both normal and pathological conditions. The enzymes that remove ubiquitin from target proteins
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 identified an apicomplexan-specific transcription factor as a key regu...
Surface antigens on pathogens are often the focus of antibodies activated by vaccines, but the variability in these antigens, particularly in RNA viruses such as influenza, HIV, and SARS-CoV-2, poses obstacles to effective vaccination. The human population encountered influenza A(H3N2) in 1968,...
When does DNA synthesis occur??? DNA replication is a semi-discontinuous process. Why is it necessary? Why is DNA called semiconservative? Why do RNA viruses mutate faster than DNA? Will the DNA replication process always create identical strands? Why or why not? What would the consequence of...
How does DNA microarray technology work? Who discovered DNA sequencing? When was HIV discovered to be a retrovirus? When is ribosomal RNA made? Where does DNA synthesis begin? When does DNA replication occur? Where is DNA polymerase made?
