How are RNA hairpin turns related to termination?
RNA hairpin turns contain a termination signal that is recognized by specific proteins involved in termination of transcription. When RNA polymerase encounters this signal, it triggers the release of the RNA transcript and dissociation of the RNA polymerase from the DNA template, marking the end of transcription.
What are exons and introns?
Intronsare intervening sequence of DNA; does NOT code for a protein.Exons are expressed squence of DNA; codes for a protein.
What is RNA processing?
1.the RNA processing transcribed from a eukaryotic gene is precessed before leaving the nucleus to serve as messenger RNA (rRNA). intro are spliced out, and a cap and tail are added. 1.the RNA processing transcribed from a eukaryotic gene is precessed before leaving the nucleus to serve as messenger RNA (rRNA). intro are spliced out, and a cap and tail are added.
What is the name given to the process in which a strand of DNA is used as a template for the manufacture of a strand of pre mRNA?
transcription
What is the process of post-transcriptional modification?
Post-transcriptional modification is a process in cell biology by which, in eukararyotic cells, primary transcript RNA is converted into mature RNA. A notable example is the conversion of precursor messenger RNA into mature messenger RNA (mRNA), which includes splicing and occurs prior to protein synthesis. This process is vital for the correct translation of the genomes of eukaryotes as the human primary RNA transcript that is produced as a result of transcription contains both exons, which are coding sections of the primary RNA transcript.
What is the RNA transcript that has the single stranded RNA?
All RNA is single-stranded. Messenger RNA (mRNA), however, is a transcript of DNA.
What enzyme attaches RNA nucleotides the the exposed 3' end of a growing mRNA transcript?
RNA Polymerase

What is spliced together during RNA processing?

What enzyme binds to DNA and is responsible for making a transcript RNA of DNA?
RNA polymerase is the enzyme responsible for binding to DNA and synthesizing a complementary RNA strand during transcription.
In eukaryotic cells the mRNA is processed and migrates from the to the .?
The mRNA produced by transcription is similar to a rough cut of a film that needs a bit of editing. A specialized nucleotide is added to the beggining of each mRNA molecule, which forms a cap. It helps the mRNA starand bind to a ribosome and prevents the strand from being broken down to fast. The end of the mRNA molecule gets a string of A nucleotides, called the tail, that helps the mRNA molecule exit the nucleus.

transcription
What macromolecule is built during transcription?
mRNA (and other RNA) molecule is built during transcription of DNA. mRNA transcript undergoes for processing to become mature. They transported to cytoplasm for the protein synthesis.
What are the differences between mature rRNA and a primary rRNA transcript?
Mature rRNA is the end product of post-transcriptional processing of the primary rRNA transcript. The primary rRNA transcript undergoes multiple processing steps, including cleavage and modification, to generate mature rRNA. Mature rRNA is functional in ribosome assembly and protein synthesis, while the primary rRNA transcript requires processing to become functional.
