Answer is basalt.
Basalt is fine grained igneous rock which contains 45 to 53% silica and 65% rich is feldspar in the form of plagioclase( silicate rock forming mineral). Feldspar is an abundant rock forming mineral. In basaltic rocks the feldspar is silica.
The basalt rocks contains pyroxene group in its minerals which gives it black color. So rocks containing many dark silicate minerals and plagioclase feldspar have basaltic composition.
Answer: An operon is described as a functioning unit of DNA that possesses cluster of genes, which are present under the control of single promoter. This means that all the genes of operon are transcribed at the same time to form a single polycistronic mRNA strand that codes for multiple proteins.
- An operon primarily consists of operator ( to which repressor protein binds, which is produced by regulatory gene and inhibits the expression of structural genes).
- promoter ( to which RNA polymerase binds and initiates transcription).
- structural genes/genes of an operon that are present downstream of promoter and are transcribed and translated to produce proteins.
Inducer is a protein molecule, binds to regulatory protein and brings change in its conformation so that it can no longer bind to an operator, thus switching on the operon.
Thus, the correct answer for blanks is-
1) operon
2) genes of an operon
3) promoter
4) regulatory gene
5) operator
6) repressor
7) inducer
