Are any organelles present in only plant cells?
Every cell has organelles. Prokaryotes were once thought to have no organelles but some have been found now. Eukaryotes have membrane bound organelles and prokaryotes do not.
Plasma membranes that have been isolated from red blood cell are not contaminted by internal cell membane?
Plasma membranes isolated from a red blood cell will not be contaminated with internal cell membrane (i.e. membrane from cell organelles - small structures found within cells) because red blood cells do not contain any organelles, so there will be no 'internal membrane' to contaminate.
How many genes are ona human chromosome?
In recent study it has been found that there are about 20,000 to 25,000 genes in our genome.Most of the sequences in our genome does not code for anything. Junk DNA or introns constitute about 90% of our genome.
What continents have monotremes fossils been found on?
Almost all monotreme fossils have been found in Australia. An exception is the fossil of a platypus-like creature named Monotrematus sudamericanum found in Argentina, within a Patagonian rock formation.
What genes cause CMT4?
There are three different genes that have been associated with CMT4 as of early 2001. They are called MTMR2, EGR2, and NDRG1. More research is required to understand how mutations in these genes cause CMT.
Are hox genes found in bacteria?
Hox genes are a hallmark of multicellular life and are not found in bacteria. Hox genes are just one type of a larger family of gene called "homeobox genes" (watch out, they sound similar!). Bacteria have genes that resemble homeobox genes (Kant et al. 2002) but they're only distantly related to those in multicellular life (Derelle, 2007), and definitely don't have Hox genes. Both plants and animals have homeobox genes, including the subset called Hox genes. The homeobox genes were first found in the fruit fly Drosophila melanogaster and have subsequently been identified in many other species, from insects to reptiles and mammals.Homeobox genes were previously only identified in bilateria but recently cnidaria have also been found to contain homeobox domains and the "missing link" in the evolution between the two has been identified.Homeobox genes have even been found in fungi, for example the unicellular yeasts, and in plants.But no evidence of hox genes are found in bacteria

Is a mitochondria in a plant cell animal cell or both?
-Mitochondria are organelles within eukaryotic cells -Mitochondria themselves are not cells, but are believed to have once been a cell themselves because they have a double membrane and their own genetic material...DNA -Plant and animal cells are eukaryotic
Has all human genes been identified and named?
Most, but not all human genes have been identified and named.
Most sex-linked genes are found on which chromosome x y?
Many sex-linked genes are found on the X chromosome. More than 100 sex-linked genetic disorders have now been mapped to the X chromosome. The human Y chromosome is much smaller than the X chromosome and appears to contain only few genes.

What are grinding stones made of?
They are found within the environment and picked up to be used.
What are the cell organelles that present only in eukaryotic cell?
The organelles found only in eukaryotic cells includes endoplasmic retculum, mitochondria, chloroplast, Golgi complex, lysosomes, endosomes, peroxisomes and glyoxisomes, and a distnct nucleus.

Why has Excedrin been removed from store shelves?
There has been a few lots of the drug Excedrin that were found to have fragments of tablets of other drugs within the bottle. Exact details of what was found I don't believe was released.
Can DNA be found in bacterial cells?
no.chromatin is not found in prokaryotes . because they don't have true nucleus
