BIOXII06: MOLECULAR BASIS OF INHERITANCE
343366
Structural genes in Eukaryotes possess coding and non-coding sequences called as 1 and 2 respectively
1 1- exons, 2- neutrons
2 1- exons, 2- Introns
3 1- Introns, 2- Exons
4 1-Enhancer, 2- Silencer
Explanation:
In Eukaryotes, coding sequence are expressed as exons. Exons are interrupted by Introns which are also called non coding sequence. These does not appear in mature or processed RNA.
BIOXII06: MOLECULAR BASIS OF INHERITANCE
343367
When RNA polymerase associates transiently with \(\sigma\) (sigma) factor
1 Transcription is terminated
2 Translation is initiated
3 Transcription is initiated
4 Translation is terminated
Explanation:
\(\sigma\) (sigma) factor acts as initiator during transcription in prokaryotes.
BIOXII06: MOLECULAR BASIS OF INHERITANCE
343368
Which of the following is incorrect?
1 RNA polymerase III helps in transcription of t RNA
2 RNA polymerase II transcribes precursor of mRNA
3 RNA polymerase III helps in transcription of 5 sr RNA
4 RNA polymerase II is responsible for transcriptionof tRNA, 5 sr RNA & snRNA.
Explanation:
RNA polymerase II is responsible for transcriptionof tRNA, 5 sr RNA & snRNA is incorrect.
BIOXII06: MOLECULAR BASIS OF INHERITANCE
343369
Select the wrong statement
1 Sigma subunit of RNA polymerase recognizes the promoter
2 Monocistronic mRNA is produced in Eukaryotes
3 In prokaryotes the primary mRNA transcript undergoes splicing
4 Transcription occurs in cytoplasm in prokaryotes cytoplasm
Explanation:
Prokaryotes genome doesn't have Introns hence the splicing mechanism doesn't takes place in it.
