what is transcription? it is the process by which genetic information is copied from DNA to RNA
The process by which RNA reads the genetic code is called? Transcription
what is mRNA? it is the messenger robonucleic acid
what does mRNA do? it helps in the transfer of genetic information from DNA to the ribosome
what enzymes are needed for transcription? RNA polymerase, also requires helper proteins
________ enzyme is used for the synthesis of RNA RNA polymaerase
what is a replicon? It is a DNA molecule that is able to replicate and be maintained
________ RNA polymerase makes tRNA's RNA polymerase 3
The synthesis of mRNA based on a DNA template is called? transcription
_________ catalysis the synthesis of RNA from a DNA template RNA polymerase
what are some products of transcription? mRNA, tRNA and rRNA
Sigma factor recognizes the _______ promoter
_______ is the recognition site of RNA ploymerase promoter
what does the first step of transcription called? pre-initiation
what happens during pre-initiation? co-factors and RNA polymerase unwind the DNA to make an initiation bubble
what is the second step of transcription? initiation
what happens during initiation? transcription factors help the RNA polymerase attach to the correct spot on the DNA
what are transcription factors? they are proteins that help the RNA polymerase bind to the DNA molecule
what is the third step of transcription? promoter clearance
what is the fourth step of transcription? elogation
what is the fifth step of transcription? termination
what happens during promoter clearance? the promoter proteins help the RNA polymerase to clear the promoter region of the DNA
what happens if the RNA polymerase does not need the promoter proteins? it falls off the DNA
what happens during elongation? polymerase moves through the antisence strand putting the correct nucleotide in order making a longer mRNA strand
during which phase of interphase does transcription occur? G1
_______ first binds to TATA box during transcription TF II D
