How can DNA be transcribed to RNA? How is DNA replicated? How is mRNA synthesized from DNA? How does DNA replicate? How do you replicate a strand of DNA? How is DNA organized in the nucleus in dividing and nondividing cells? How is RNA formed from DNA?
Explain how DNA is packaged or organized within the cell. How is the structure of prokaryotic and eukaryotic cells related to how their DNA is replicated? Briefly describe what you know about the structure of DNA and how DNA is packaged in a cell. ...
Prokaryotic and eukaryotic chromosomal DNA is organized in different ways. Due to the circular nature of most prokaryotic chromosomes, they are often highly supercoiled under normal growth conditions. In contrast, eukaryotic chromosomes are linear and packaged using histone proteins, which are not ...
Bacteria, however, lack a nucleus, and their DNA floats freely within the cell. These microscopic cells don't have organelles and possess different methods to reproduce and swap genetic material. Bacteria are classified as prokaryotic cells. Basic categories aside, scientists also place bacteria in ...

Single-nucleotide-resolution chemical RNA structure probing is emerging to explore the folding state of the transcriptome in living cells; the resulting models for how 5′ UTR structures impact translation should be validated by compensatory mutagenesis.Abstract...
Streptococcus suis is a zoonotic agent that causes sepsis and meningitis in pigs and humans. S. suis infections are responsible for large economic losses in pig production. The lack of effective vaccines to prevent the disease has promoted the extensive
Therefore, the manipulation of protein-protein interactions is essential for the development of any cell controlling system. Since proteins are the workhorses of cells, these have been the main focus of most of the research involving control of cellular behavior. Proteins interact with ea...
There is increasing evidence that in both eukaryotic and prokaryotic cells, enzymes are organized into higher order assemblies. In metabolism, such assemblies may take the form of metabolons [23] which may themselves be associated into still higher order hyperstructures [24,25]. In signaling, chem...
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. Do prokaryotic cells have RNA? (a) What are snRNPs? (b) How are they involved in the eukaryotic mRNA splicing reaction?
