Asseration: RNA produced during transcription in eukaryotic cells cannot be straight away used in photosynethsis. Resson : RNA splicing phenomena helps in the removel of exons.

Compare the statements A and B . Statement A : RNA produced during transcription in eukaryotic cells cannot be straight away used in photosynthesis. Statement B : RAN splicing phenomena help in the removal of exons . Choose the correct description.

During transcription in eukaryotic cell the RNA splicing and RNA cappling takes place inside the

Assertion : In transcription only a segment of DNA and only one of the strands is copied into RNA. Reason : The process of replication, once set in, duplicates the total DNA os an organism.

Assertion (A) : Replication and transcription occur in the nucleus but translation occurs in the cytoplasm. Reason (R ) : m-RNA is transferred from the nucleus into the cytoplasm where ribosomes and amino acids are available for protein synthesis.

Statement A : The primary transcript produced in eukaryotic is translated without undergoing any modification or processing. Statement B: The hn-RNA in humans has exons and introns.

Select the correct statements regarding the process of transcription in eukaryotes. (i) The strand of dsDNA which takes part in transcription process is called as coding strand. (ii) The enzyme RNA polymerase can catalyse polymerisation only in one direction i.e. , 5' rarr 3' . (iii) An unusual nucleotide methyl guanosine triphosphate is added to the 5' end of hnRNA during capping. (iv) During tailing process, adenylate residues (200-300) are added at 3' end in a template independent manner.

Transcription is the mode in which DNA passes its genetic information to RNA. Transcription takes place in the cytoplasm of eukaryotic cells.

Assertion (A) Transcription unit is often monocistronic in eukaryotes and polycistronic in prokaryotes Reason ( R ) Exons do not appear in mature RNA, introns appear is mature RNA.
