DNA: DNA (Deoxyribonucleic acid) is the molecule that houses an organism's genetic information. DNA is found in the nucleus of every cell in the human body. Chromosomes are thread-like structures that contain DN
How the structure of DNA contributes to a cell's ability to replicate it? How does the structure of DNA fit its function, especially as it relates to DNA replication? Describe how eukaryotic DNA is arranged in the cell. How does supercoiling take place in eukaryotic DNA?
The terms ‘eukaryote’ and ‘prokaryote’ were introduced Edouard Chatton in 1925 (Chatton, 1925, cited in Sapp, 2005). Eukaryotes, according to the online Oxford Dictionaries is a cell in which DNA is arranged in chromosomes that are “contained within a distinct nucleus”. The name prokary...
First, the cells, to produce a glassy solid and dried cultured or incubated under conditions sufficient to induce intracellular trehalose, was suspended in stabilizing solution. It is storage stable at room temperature, the resulting product, show little decrease in viability during storage.タンナク...
To bring clarity, the term ‘information’ is resolved into three distinct meanings: physical pattern, statistical relations and knowledge about
In plastids, newly synthesized transcripts undergo several maturation steps prior to translation. Most genes are arranged in polycistronic gene clusters and transcribed from a single promoter (Herrmann et al.1992; Sugiura1992). As translation of monocistronic RNAs is often more effective than translati...
Identify the three component parts of a nucleotide and explain how each is arranged in a DNA molecule. Molecular characterization of bacterial species often relies on the sequencing of ribosomal rRNA genes. In the project to identify unknown species, why PCR needs to be do...
An understanding of how cell-autonomous immunity has evolved in primates is crucial to understanding the human evolutionary story, not only because multiple infectious agents thought to have strongly affected human genomic evolution are excellent manipulators of cell-autonomous immunity, but because these ...
How do the nucleus and ribosomes work together to generate a protein? How does the organization of genetic material differ in prokaryotic and eukaryotic organisms? How is ribosomal DNA arranged on chromosomes? How is the nucleus involved in protein synthesis?
How is the structure of prokaryotic and eukaryotic cells related to how their DNA is replicated? Why don't prokaryotes have telomeres? Why don't prokaryotes use the same siRNA system that eukaryotes have? Do they both get infected by viruses...
