RNA transcription

What is the function of RNA polymerase in the trancription process?

• Addition of a second mRNA strand

• Supercooling of the DNA strand

• Sticking mRNA fragments to be together

• Catalysis and speed up the process

DNA strands contain thymine as one the nitrogenous bases in the mRNA strand, however, thymine is replaced with

• Adenine

• Thymine

• Uracil

• Citosyne

• Guanine

The end product of transcription is a double-stranded mRNA, that contains information on the proteins that need to be synthetized

• TRUE

• FALSE

The template strand of DNA is read in the _______ direction, which means that the mRNA strand is synthetized in the 5' to 3' direction.

Which of these steps are NOT a part of the initiation stage of transcription

• RNA polymerase searches and binds to the promoter region

• RNA polymerase and the promoter unwind the DNA

• DNA polymerase prevents the supercooling of DNA during unwinding

• The 3' 5' strand is used as a template strand to start mRNA formation

During initiation process...

• An RNA transcript that is ready to be used in translation is called a messenger RNA (mRNA)

• RNA strand gets longer, thanks to the addition of new nucleotides.

• RNA polymerase binds to the DNA of the gene at a region called the promoter.

During elongation process...

• An RNA transcript that is ready to be used in translation is called a messenger RNA (mRNA)

• RNA strand gets longer, thanks to the addition of new nucleotides.

• RNA polymerase binds to the DNA of the gene at a region called the promoter.

During termination process...

• An RNA transcript that is ready to be used in translation is called a messenger RNA (mRNA)

• RNA strand gets longer, thanks to the addition of new nucleotides.

• RNA polymerase binds to the DNA of the gene at a region called the promoter.
