Web13 aug. 2024 · When DNAse and RNAse (enzymes that degrade DNA and RNA, respectively) were added to the molecules, the application of DNAse eliminated the trunk structures, while the use of RNAse wiped out the... WebStep 1: Initiation. Initiation is the beginning of transcription. It occurs when the enzyme RNA polymerase binds to a region of a gene called the promoter. This signals the DNA to unwind so the enzyme can ‘‘read’’ the bases in one of the DNA strands. The enzyme is now ready to make a strand of mRNA with a complementary sequence of bases. gettysburg movie theater times

Certain proteins called transcription factors unwind the DNA strand and allow the enzyme RNA polymerase to transcribe only a single strand of DNA into a single stranded RNA polymer called messenger RNA (mRNA). Web31 aug. 2024 · As it separates the two strands, RNA polymerase builds a strand of mRNA by adding the complementary nucleotides (A, U, G, C) to the template strand of DNA. A specific set of nucleotides along the template strand of DNA indicates where the gene starts and where the RNA polymerase should attach and begin unravelling the double helix. gettysburg movie youtube scenes
