The transcription of RNA from DNA takes place in several steps. In which step of transcription does RNA polymerase actively build the mRNA strand by attaching RNA bases to one another one by one by using the DNA as a template?
Initiation
Elongation
Termination
Translation
What is the first step in the transcription of DNA into mRNA?
RNA Polymerase binds to the promoter region on the template DNA strand.
RNA Polymerase adds nucleotides to the mRNA to create matching base pairs.
RNA Polymerase breaks the DNA strand so that it exists as a short segment corresponding to the length of an mRNA.
RNA Polymerase breaks in half and each half binds to a different strand of DNA
What happens to the mRNA sequence after it has been synthesized?
stays in the nucleus
leaves the cell
leaves the nucleus
separates into smaller pieces
Which of the following statements regarding a final processed mRNA is correct?
Exons are included in the protein sequence, while introns are left out
Introns are included in the protein sequence, while exons are left out
Exons and Introns can both be included or left out depending on the protein
Exons and Introns are both part of the mRNA sequence, but only exons are part of the rRNA and tRNA
The process of modification of pre mRNA is known as___________
Replication
DNA repair
Translation
RNA processing
During RNA processing the regions that being removed are
Intron
Exon
The specialized organelles that conduct RNA splicing by removing of intron and joins together the two exons are
RNA polymerase
spliceosome
Primer
Helicase
Which of the following is the correct statement about alteration of mRNA ends?
Guanine is added to the 5’ end
Introns are removed and exons are spliced together
Histone mRNAs lack 5’ cap
Poly-A tail is added to the 3’ end
