Any process involved in the conversion of a primary ribosomal RNA (rRNA) transcript into a mature rRNA molecule.

Any process that modulates the frequency, rate or extent of establishment of a pattern of pigment in the eye of an organism.

transcription from RNA polymerase II promoter

The synthesis of RNA from a DNA template by RNA polymerase II (Pol II), originating at a Pol II-specific promoter. Includes transcription of messenger RNA (mRNA) and certain small nuclear RNAs (snRNAs).

Any process that activates or increases the rate, frequency or extent of establishment of a pattern of pigment in the eye of an organism.

transcription initiation from RNA polymerase II promoter

transcription initiation from Pol II promoter

Processes involved in starting transcription from the RNA polymerase II promoter.

RNA elongation from RNA polymerase II promoter

The extension of an RNA molecule after transcription initiation at an RNA polymerase II-specific promoter by the addition of ribonucleotides catalyzed by RNA polymerase II.

transcription termination from RNA polymerase II promoter

transcription termination from Pol II promoter

Any process by which transcription by RNA polymerase II is terminated.

Any process that modulates the frequency, rate or extent of establishment of a pattern of pigment in the cuticle of an organism.

Processes involved in starting transcription, which is the synthesis of RNA by RNA polymerases using a DNA template.

Any process that alters the rate or extent of melanin biosynthesis.

The process by which transcription is completed; the formation of phosphodiester bonds ceases, the RNA-DNA hybrid dissociates, and RNA polymerase releases the DNA.

negative regulation of melanin biosynthesis

negative regulation of melanin synthesis

Any process that stops, prevents or reduces the rate or extent of melanin biosynthesis.

The extension of an RNA molecule after transcription initiation by the addition of ribonucleotides catalyzed by an RNA polymerase.
