Which type of RNA polymerase enzyme transcribes precursor mRNA?

In 1958 Francis _____ proposed that DNA determines the sequence of amino acids in a polypeptide through mRNA, this is the main principle or central dogma of protein synthesis. (Write the last part of the name)

DNA mRNA Protein
Identify the process"X" in the given flow chart.

Find out the series of genes in the transcription unit of the following statements.
I. Located towards 3 '-end of the structural gene.
II. Flanked by the promoter and the terminator.
III. Located towards 3'-end of the coding strand.

Match the following
List-I | List - II | List -III |
i) | I) Transported out of nucleus | |
ii) Addition of methyl guanosine triphosphate |
II) 3 'end | |
C) Caping | iii) m-RNA | III) Transcribes by RNA polymerase |
D) Processed hn RNA |
iv) Addition of Adenylate Residue |
IV) 5 ' end of hn RNA |
The correct answer is

Assertion (A) : During transcription both the strands of DNA are copied
Reason If both strands act as template DNA would code for RNA molecule with different sequences

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
The correct answer is

What is the corresponding sequence of when a polynucleotide template strand is ?

Read the following statements and choose the correct option.
(i) Tailing: It is addition of adenylate residues at 5' -end in a template independent manner.
(ii) Promoter: It is the site recognised by the RNA polymerase in association with factor.
(iii) Division of labour: RNA polymerase I and RNA polymerase III are responsible for 18S rRNA and tRNA transcription respectively.
(iv) Capping: addition of methyl guanosine triphosphate at the 5'-end of hnRNA.

If the template strand of DNA is identify the sequence of RNA transcribed.

Find out the series of genes in the transcription unit of the following statements
(I) Located towards ' end of the structural gene
(II) Flanked by promoter and terminator
(III) Located towards ' end of the coding strand

The process of transcriptional termination is catalysed by
