The central dogma of molecular biology is a theory stating that genetic information flows, only in one direction from DNA to RNA to protein or RNA directly to protein. DNA \(\rightarrow\) RNA \(\xrightarrow{\text { translation }}\) Protein

Genes that are involved in turning on or off the transcription of a set structural genes are called
1 polymorphic genes
2 operator genes
3 redundant genes
4 regulatory genes
Explanation:
Lac operon is made up of regulator operator and structural gene. The regulator gene produce m-RNA which translates into the repressor. The repressor attaches to the structural gene in absence of inducer. In presence of inducer, the repressor attaches to the inducer and operator is not blocked so it allows the expression of the structural gene. Operator genes are a region of DNA sequence which attaches to repressor molecule and stop the expression of the structural gene.

A sequential expression of a set of human genes occurs when a steroid molecule binds to the:-
1 Ribosome
2 Transfer RNA
3 Messenger RNA
4 DNA sequence
Explanation:
When a steroid molecule binds to a specific set of DNA sequence, the receptor protein at the steroid hormone complex activates a sequential expression of genes. The steroid molecules acts and an inducer.

The terminator gene technology causes
1 failure of seed setting after one generation
2 breakage of seed dormancy
3 early flowering in plants
4 None of the above
Explanation:
In terminator gene technology, the plants are introduced a gene, called terminator gene, which causes failure of seed setting after one generation.
