Are amoeba cells prokaryotic or eukaryotic? Eukaryotic cells, like those of animals, are more complex than those of prokaryotes, like bacteria. List two similarities and three differences between eukaryotic and prokaryotic cells. Do helminths have a nucleus?
Compare prokaryotes and eukaryotes about DNA that is NOT part of the nucleus/nucleoid. How are genes transcribed in prokaryotes? Is the nucleus the sole source of DNA in a eukaryotic cell? (a) What is RNA? (b) How is RNA produced?
Only the cells of advanced organisms,known as eukaryotes, have a nucleus. Generally there is only one nucleus per cell, but there are exceptions, such as the cells of slime molds and the Siphonales group of algae. Simpler one-celled organisms (prokaryotes), like the bacteria and cyanobacteria...
When present, the cell has just one flagellum or a few flagella. Prokaryotes sometimes have flagella, but they are structurally very different from eukaryotic flagella. Prokaryotes can have more than one flagella.They serve the same function in both prokaryotes and eukaryotes(to move an entire cell...
PDXP has not been detected in genome-wide association studies (GWAS), and pathologically relevant single nucleotide polymorphisms (SNPs) or somatic point mutations have not been reported. Interestingly, PDXP maps to a region on the long arm of chromosome 22 (22q12.3–13.2) where losses occur wit...
a Prokaryotes are single-cell organisms, such as bacteria, that have no real nucleus and do not contain membrane-enclosed organelles. Eukaryotes, such as algae, fungi and protozoa, have a real nucleus and membrane-enclosed organelles. Viruses are tiny, complex molecules composed of protein and nu...
Gene expression is not always an all-or-nothing process, however. Within prokaryotes, genes can be expressed to varying degrees. The exact degree of expression is controlled by a stack of molecules called CAP-cAMP, which binds to DNAupstreamof the promoter (i.e. on the 5' side of the pr...
prokaryotes. Consequently, PBPs and class A, C, and D ß-lactamases being acyl serine transferases are considered to be bacteria specific [156]. But structural homologies between bacterial- and human serine proteases are conceivable as eukaryotic acyl serine transferases like trypsin, thrombin, ...
Which glial cells have the most diversity of function? What functional advantage does a neuron with several dendrites have? Which type of blood cell cannot move like an amoeba? What function does mitochondria have in prokaryotes? What is the function of the mitochondria in the eukaryotic cell?
