Question

Here is all the information and content! One of the questions which shows a double stranded sequence and asks for the mRNA sequence has not correct answer. It should be dropped.
Anyone who majored in Bio can answer these 2nd-year biology multiple questions (only Q14 has more than one answer). Thanks a lot!!!!!

TATA box b. initiator element O C. +1 site od. Pribnow box e. upstream element

Answer 1

1. Small nuclear RNAs.

Small nuclear RNAs ( U1, U2, U4, U5 and U6) play impotent role in splicing.

2. 5' ACGUAUUGC 3'.

3. Pribnow box.

TATA box in eukaryotes called goldberg - hongness box.

TATA box in prokaryotes called pribnow box.

4. A hypothetical sequences based on frequency of nucleotides in aligned sequences.

5. Omega and sigma

RNA polymerase holoenzyme have two components core polymerase(beta 2,alpha and alpha prime) and sigma 70 subunit. The enzyme with out sigma factor is called as core polymerase. Sigma factor is not required for the basic catalytic activity of enzyme.

6. Transcription bubble

7. Rho factor

8. RNA polymerase

In prokaryotes a single type of RNA polymerase appears to be responsible for all most all synthesis of mRNA, rRNA and tRNA.

9. TFIID

10. HDAC

Histone deacetylases removes acetyl group from N-acetyl lysine aminoacid on a histone.

11. 3' OH of 3' exon

12. U1

U1 small nuclear RNA base pairing is necessary for splicing. U1 RNA has 3' CAUUCAU 5' sequence which recognizes the complementary 5' splice sequence in an Intron.

13. CPSF

14. Exons may be shuffled and Catalysis mediated by mRNA itself.

15. None of the answers are correct. All of the RNA listed here requires processing.

16. Formation of the open complex
