Classification ConundrumsIn recent messages, the classification of organisms has been explored. This will continue for the next several messages. Some clarity has been achieved and some problems identified.
There are several classification systems for organisms, which of course, is only useful if separating wheat from chaff and blending what's left is the process used. One classification approach uses differences in nucleotides in the cell's ribosomal rNA's, as one of several criteria. This approach starts in the late stages of life. However, nucleotides are wheat because they contain seeds. This orients us in the right direction back towards more seeds within seeds: groups, compounds, molecules elements, atoms, subatomic particles, sub-sub-atomic particles (elementary particles) and the essence of the nucleus.
Ribozymes Are Catalytic rNA's Are EnzymesA ribozyme is a fancy word for rNA that is functioning as a catalyst for chemical reactions. rNA has the ability to change shape (structure) in order to cause a change in the rate of chemical reactions. In many chemical reactions, proteins are the catalyst. Protein catalysts are simply called enzymes. Why? Why not “prozymes?”
Although protein enzymes were discovered in past Ages, they were discovered again during this Age. Afterwards, rNA was understood to also be an enzyme. Ribonucleic acid (rNA) functioning as an enzyme was called a ribozyme (ribo + enzyme). Therefore, a ribozyme is rNA, thus it still has an less stable, more reactive ribose sugar compound attached.
There is nothing different between ribozyme and rNA except how the rNA is folded, which then alters how rNA functions and alters which word we choose to use. Fold rNA one way, it's rNA. Fold the same rNA another way, it's a ribozyme. As a reminder, we must not forget and overlook the relationship between rNA and proteins.
rNA carries the computer code scripts and algorithms to assemble amino acids into proteins.
rNA also assembles amino acids into proteins in ribosomes.
rNA also carries the computer code to construct* ribosomes.
A ribosome is a ribozyme. Thus, this is where we can see both in existence at the same time in the same place in the same thing – the ribosome.
We are in the rNA “zone” in the “some” with the “zyme.”
Even so, rNA and ribosomes exist in many places within cells. The fact that rNA carries the written instruction codes in program language for proteins, and the fact that rNA also assembles proteins, does not mean rNA existed first.
(a) complete the structure. Com + struct = comstruct = construct because "m" and "n" interchange.
(b) complete instructions. Com + struct = comstruct = construct.
Now we have four meanings:
1. Complete the structure
2. Per instructions.
3. Per complete instructions.
4. Compare and contrast structure to structions. (Analyze the results)
