A: Production of hirudin from transgenic Brassica required use of synthetic gene.
R : Eukaryotic genes have intron sequences that need to be spliced out.

Correct the statements if required by changing the underlined words: Eukaryotic chromosomes have coding and non-coding sequences. Noncoding sequences are introns.

Assertion : Split genes are found in eukaryotes. Reason : Introns or intervening sequences are found in prokaryotes.

Assertion :- The split-gene arrangement complicates the definition of a gene in terms of a DNA segment. In eukaryotes the monocistronic structural genes have interrupted coding sequence.

Assertion :- The split-gene arrangement complicates the definition of a gene in terms of a DNA segment. In eukaryotes the monocistronic structural genes have interrupted coding sequence.

Read the following statements and select the corect ones. i. Monocistronic structural genes in eukaryotes have uninterrupted coding sequences, ii. Coding sequences of a gene are called exons.iii. There is a single DNA-dependent RNA polymerase that catalyses transcription of all types of RNA in bacteria.iv. In eukaryotes, RNA polymerase.. lll is responsible for the transcription of 28S rRNA
