some enzymes present in certain organelles only , such specific enzymes are called marker enzymes
The enzyme is inactive at this point. New enzyme must be added to regain enzyme activity
a physical marker may or may not appear inthe given situation but a gene marker does appear because it is genetically governed.
enzyme-substrate complex
Such an enzyme is called a restriction endonuclease
It is an enzyme...
Enzyme used as a marker for liver cancer.
A reporter enzyme monitors transformation of host cells by foreign DNA in addition to a selectable marker through insertional inactivation. It differentiates recombinants from non recombinants.
gamma-GTPase is the most common marker enzyme used to detect the prostate cancer.. prostate cancer is most commonly seen in the mid people of 50-60 years age.
Isolation of any organelle requires a reliable test for the presence of the organelle. Typically, this is done by following the activity of an enzyme that is known to be localized exclusively in the target organelle. Such enzymes are known as marker enzymes. For example, the enzyme acid phosphatase (that cleaves terminal phosphate group from substrates and has a pH optimum in the acidic range) is localized in lysosomes, while the enzyme succinate dehydrogenase is localized in mitochondria. By monitoring where each enzyme activity is found during a cell fractionationprotocol, one can monitor the fractionation of lysosomes and mitochondria, respectively. Marker enzymes also provide information on the biochemical purity of the fractionated organelles. The presence of unwanted marker enzyme activity in the preparation indicates the level of contamination by other organelles, while the degree of enrichment for the desired organelle is determined by the specific activity of the target marker enzyme. Although marker enzymes reveal much concerning the purity of the organelle preparation, electron microscopy is generally used as a final step to assess the preparation's purity and the morphology of the isolated organelle.

some adjectives for marker could be: blue marker, red marker, black marker
data marker

A felt marker is simply called a marker or felt marker.
With is not a dependent marker.
Halfway between mile marker 25 and mile marker 27.
This is a non-lateral marker. It can indicate a controlled area, such as no wake. It can be an informational marker, a "keep out" marker, or a warning marker (Dam, Rock, etc)
