Transcription is the process that stops when RNA polymerase is terminated.
What else can I help you with?
What is the difference between the terminator sequence and the stop codon in genetic transcription and translation processes?
The terminator sequence marks the end of a gene during transcription, signaling the RNA polymerase to stop. The stop codon, on the other hand, signals the end of protein synthesis during translation, causing the ribosome to release the completed protein.
The correct sequence of the events of transcription is?
RNA polymerase reaches the beginning of a gene.
Describe the process of transcription in biology?
This process occurs in the nucleus of a cell. Firstly DNA helicase, will break the hydrogen bonds holding together the two strands of DNA. This exposes the bases on the two strands. RNA polymerase then anneals free nuleotides via phosphodiester bonds, via complementary base pairing to one strand of DNA, known as the template strand. Thus a strand of pre-messenger RNA is built, as the RNA polymerase moves along the DNA strand, the two DNA strands join up behind it. RNA polymerase stops the process of transcription when it reaches stop codons, which tell the enzyme to stop annealing nucleotides. The product is a length of pre-mRNA, which can then leave the nucleus throguh the nuclear pores and undergo splicing to remove introns and then translation.
How does RNA polymerase know where to start transcribing a gene into mRNA?
The enzyme that synthesizes RNA (RNA polymerase) binds specific DNA sequencesthat typically lie before the gene being transcribed. When everything it needs to start synthesis is properly assembled (any cofactors, etc.), only then can it begin transcribing DNA into RNA.
What determines where on the DNA molecule transcription begins and where it ends?
Transcription begins at the promoter region on the DNA molecule. This region contains specific sequences that are recognized by RNA polymerase to initiate transcription. Transcription ends when RNA polymerase reaches a termination sequence on the DNA molecule.
What is the terminator in mRNA synthesis?
The terminator in mRNA synthesis is a specific DNA sequence that signals the end of transcription. When the RNA polymerase reaches the terminator sequence, it stops transcribing the mRNA molecule, releasing it from the DNA template.
What is the difference between the terminator sequence and the stop codon in genetic transcription and translation processes?
The terminator sequence marks the end of a gene during transcription, signaling the RNA polymerase to stop. The stop codon, on the other hand, signals the end of protein synthesis during translation, causing the ribosome to release the completed protein.
What signals the termination of translation?
Translation terminates when a stop codon (UAA, UAG, or UGA) is reached in the mRNA. This stop codon is recognized by release factors, which promote the release of the completed polypeptide chain from the ribosome.
Does transcription begin at a promoter region and continue until RNA polymerase reaches a stop codon?
Transcription begins at a promoter region on the DNA where RNA polymerase binds to initiate the process. It continues along the DNA template strand until it reaches a termination signal, not a stop codon, which signals the end of transcription.
The correct sequence of the events of transcription is?
RNA polymerase reaches the beginning of a gene.
What cause RNA polymerase to stop transcribing mRNA?
RNA polymerase stops transcribing mRNA when it encounters a termination signal in the DNA sequence, typically a specific sequence of nucleotides that signals the end of a gene. This signal can be formed by specific sequences that lead to the formation of a hairpin loop in the RNA, causing RNA polymerase to dissociate from the DNA template. Additionally, termination factors may assist in this process, ensuring that transcription is completed accurately.
How does transcription end?
Transcription ends when RNA polymerase reaches a terminator sequence on the DNA template strand. This signals the enzyme to stop synthesizing the RNA transcript and release it. The RNA transcript is then further processed and can be translated into a protein.
Who would win in a fight the Terminator or Robocop?
Terminator. Robocop is about on the level of Master cheif. The more human you are when fighting a machine the weaker you are. Terminator would wipe the floor with Robocop. lets compare. 1.Terminator is programmed to repare itself if it gets hurt. 2.If he is programmed, a machine is way harder to discourage, and stop, than a human. I think the last answer was pretty good, but i do not think that it was very well thought out. Is a human really going to be more tenacious than a Machine? no Terminator.
How do you use terminal in a sentence?
Get off the bus at the terminal, there will not be another stop after that stop.
Why is it necessary to have a primer on each side of DNA segment to be amplified?
Primers are necessary on each side of a DNA segment to be amplified because they provide a starting point for DNA polymerase to initiate replication. Each primer binds to its complementary DNA strand, allowing the polymerase to synthesize new DNA in the 5' to 3' direction. By having primers on both sides, the entire target region can be amplified in a process called polymerase chain reaction (PCR), producing multiple copies of the specific DNA segment. Without primers on both ends, the DNA polymerase would not know where to start or stop, preventing efficient amplification.
How does DNA polymerase know when to stop adding nucleotides?
DNA polymerase knows when to stop adding nucleotides primarily due to the presence of a specific DNA sequence known as a termination signal. In prokaryotes, this can be a specific sequence in the DNA that causes the polymerase to dissociate. In eukaryotes, termination often involves interactions with proteins and specific signals that indicate the end of a gene. Additionally, the DNA template's structural features can also play a role in signaling the completion of replication.
What determines where on the DNA molecule transcription begins and ends?
Transcription begins at a specific DNA sequence called the promoter region, which signals the RNA polymerase enzyme where to start transcribing. Transcription ends at a specific DNA sequence called the terminator region, which signals the RNA polymerase to stop transcribing. These regions, along with other regulatory elements, help determine the initiation and termination points of transcription.
