Why is transcription referred to ”DNA-Directed RNA synthesis”?
- A. The RNA sequence directs the synthesis of the template DNA strand.
- B. The sequence of the RNA strand is transferred to the DNA.
- C. RNA is synthesized using a template DNA strand.
-
D. A double stranded RNA is synthesized using a single stranded RNA.
Homework Answers
Answer - (c)
Transcription is referred to "DNA Directed RNA synthesis" it is because the RNA synthesized in the process of transcription using the template DNA strand. RNA's copy involves in this is done with the help of DNA template strand.
Thank you

The process of DNA transcription: produces single stranded RNA complementary to the coding strand. requires RNA polymerase. is discontinuous. produces double stranded DNA. requires DNA polymerase III. Among the significant sites that many eukaryotic promoters contain is: a TATAAT box near –10. a TATA site near –30 to –100. a CATA site at the transcription start site. a Pribnow box. the Shine-Dalgarno sequence.

In rho-dependent transcription termination: the formation of a hairpin in the transcribed mRNA causes RNA polymerase to pause, facilitating termination. rho binds the mRNA, and when it makes contact with RNA polymerase, it assists with the removal of the mRNA from the DNA template. the rho factor binds to the -10 consensus sequence located in the promoter region to terminate transcription. a site within the poly(A) tail is cleaved which signals termination. the 3' untranslated region (3" UTR) is synthesized....

Part A What are three observations that suggested eukaryotic RNA was an intermediate between DNA and protein? Select the three observations. O DNA plays the major role in replication, which allows for sustainable transfer of genetic information. O RNA is transported out of the nucleus and into the cytoplasm where protein translation occurs. Three types of RNA are found in the cell, and all of them are involved in protein synthesis. O DNA is found in the nucleus and protein...
