while animal cells such as humans may take up to 400 hours. In addition, eukaryotes also have a distinct process for replicating the telomeres at the ends of their chromosomes. With their circular chromosomes, prokaryotes have no ends to synthesize. Lastly,...
Topology, Type II DNA Topoisomerases and DNA Replication in Prokaryotes and EukaryotesDNA replication raises several topological questions. i) How did the two parental strands uncoil in spite of the restriction imposed to their rotation either by DNA circularity or by the barriers which segregate the...
Describe the process of translation and transcription in the cell. What is the difference between DNA and RNA and its characteristics? What differences exist between DNA replication in prokaryotes and eukaryotes? Describe Transcription, such as . . . What are the 3...
Compare the DNA replication in prokaryotic and eukaryotic cells. Compare prokaryotes and eukaryotes about DNA that is NOT part of the nucleus/nucleoid. Compare and contrast the genomes of bacteria and eukaryotes. Contrast the differences in DNA structure between prokaryotes and e...
In eukaryotes, RFBs can be found at telomeres, centromeres, highly transcribed genes, and origins of replication, among other locations [2]. Furthermore, some of these RFBs act as programmed polar pausing sites for the replication machinery in order to control other biological processes, such ...
Likewise, in eukaryotes, cells accumulate mutations as they divide. In humans, if enough somatic mutations (i.e., mutations in body cells rather than sperm oreggcells) accumulate over the course of a person's lifetime, the end result could be cancer. Or, less frequently, some cancer mutati...
DNA replication occursin the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (anti-parallel) direction...
Single-celled eukaryotes often undergo very rapid replication cycles, with complete cell doubling occurring within 90 min, and can exist in both haploid and diploid forms. These constraints mandate a replicative process of high integrity under tight time constraints, which is addressed in part by ...
What are the unique processes in meiosis that are not present in mitosis? Why do chromosomes, not individual genes, assort independently? Why are trinucleotide repeat diseases autosomal dominant? How does mitosis and cytokinesis in eukaryotes differ from binary fission in prokaryotes?
Mobile genetic elements and HGT in prokaryotes * Microbiota VincentBurrus, inCurrent Opinion in Microbiology, 2017 Conclusion Both small and large ICEs found in both Gram-positive and Gram-negative bacteria are capable of replication. In fact, intercellular rolling-circle replication is an intrinsic pa...
