No. Darwin published his theory in the 1850s. The structure of the DNA molecule was not worked out by biologists until around the 1950s. Darwin was long dead before molecular biology came into play to support his theory.

They are organized in a very complex manner. A gene is a term that denotes not only for a RNA or protein coding sequence but it consist of regulatory elements such as promoter, terminator and so on. And not all genes code only one single protein, neither it is coded in a linear manner. A gene can make RNA from any of its (both) strand according to the sequence message and each frames (Inda sequence of 'ATGTCC', the first frame ATG=Methionine, if it start from second from TGT which give another amino acid for example). So in theory, there are 6 possible frames (3 frames from 5' to 3' and 3 others from 3' to 5' direction) for a given piece of DNA or so called gene.
Then we this long non coding introns, and gene splicing events which tangle a bit more to study them.

Lac operon is a set of genes that regulates the digestion of lactose. In absence of lactose in the medium, the repressor protein binds to the operator that inhibit the transcription of structural genes such as beta galactosidase, lactose permease and transacetylase. This makes sure to avoid the enzyme synthesis when there is no need!
Conversely, when the lactose present in the medium, an isomer of lactose called allolactose bind to the repressor protein, the conformational change in the repressor let it to detach from repressor hence the RNA polymerase can transcribe the structural gene. Although this may be enough for synthesis of structual gene the system is tightly regulated by a protein called CAP (catabolite activator protein) and glucose.
Glucose is a preferred source of energy for cell when this desirable source is present, lactose need not be used as a energy resource. What happens is there will be low level of cAMP when there is high amount of glucose and this keeps CAP inactive.
When there is low glucose levels, the cAMP would be higher, that binds to CAP to make it active, which in turn binds to the promoter that enhance the transcription of structural genes.
Thus, for efficient transcription lac operon structural genes, lactose must be present where glucose must be absent.

Protein structures are stabilized largely by non covalent forces and the surrounding medium. Forces such as ionic bonding, Hydrogen interaction, Van der Waals forces keep the proteins stable. Disulphide linkage also plays a role in protein stability.
