Answer:
Polycistronic mRNA:
Polycistronic mRNA may be defined as the mRNA that has the ability to code multiple proteins from a single mRNA molecule. This type of mRNA is generally found in prokaryotes.
Operon:
Operon may be defined as the DNA functional unit that contains the cluster of genes. These gene are regulated by the single promoter. These operon system are generally found in prokaryotes.
Regulon:
Regulon may be defined as the group of genes that acts as a single regulatory unit. The protein expressed by regulon can acts as a activator or repressor. These are generally found in eukaryotes.
Answer is A. Calvin cycle.
Calvin cycle reactions or light independent process of photosynthesis occurs in the stroma (Ground substance) of the chloroplast. In the stroma enzymes are present for the Calvin cycle reactions. Carbon dioxide (CO₂) enters into the leaves through stomata and diffuses into stroma of the chloroplast. In the stroma carbon atoms from CO₂ is fixed into sugar (carbohydrate) with the help of energy from ATP and NADPH.
If it hits a single atom, a "product" can be broken. But only until it is a single molecule will a "molecule" be separated. Of starters, oxygen, H2O, always appears like oxygen in millions. But if you split it into smaller and lesser parts, say half, you can divide it only until you get 2 hydrogen and 1 oxygen. It's no longer water if you divide it further. It's going to be another matter.
