Transcription

Monocistronic gene is also found in prokaryotes.

Define monocistronic gene.

In what types of cells can you find monocistronic genes?

Briefly explain the process of termination of transcription in eukaryotes.

_____ factor is responsible for the process of transcription to take place in prokaryotes.

Briefly describe the process of termination of transcription in prokaryotes.

A termination sequence is a DNA sequence located towards the 3′ end (downstream) of the coding strand that provides the stop signal and ends the process of transcription.

Assertion (A): The structural gene in a transcription unit can be said to be monocistronic or polycistronic.

Reason (R): In eukaryotes, the monocistronic structural gene has interrupted coding sequence - but the genes in eukaryotes split. The coding sequence or expressed sequences are defined as exons. Exons are said to be those sequence that appears in mature or processed $\mathrm{RNA}.$
The correct answer is

The process of transcriptional termination is catalysed by

Terminator sequence is same as terminator codons.

The process of formation of mRNA from DNA is called transcription.

Name the equivalent of structural gene, whether it is exon or cistron.

DNA-dependent RNA polymerase catalyses transcription on one strand of the DNA which is called the template strand or coding strand?

The coding sequences or expressed sequences are defined as _____.

Histones are rich in the basic _____ residues lysine and arginine.

_____ are removed and exons are joined to produce functional RNA by splicing.

Lac operon is the prototype operon in bacteria, which codes for genes responsible for _____ of lactose.

When the small subunit encounters an mRNA, the process of translation of the mRNA to _____(protein/DNA/RNA) begins.

The accessibility of _____ regions of prokaryotic DNA is in many cases regulated by the interaction of proteins with sequences termed operators.

In bacteria, more than one gene is arranged together and regulated in units called as _____.
