Can replication and transcription occur simultaneously?

Can replication and transcription occur simultaneously?

In prokaryotes (organisms without a nuclear membrane), DNA undergoes replication and transcription and RNA undergoes translation in an undivided compartment. All three processes can occur simultaneously.

Is replication or transcription faster?

Replicated DNA strand remains hydrogen bonded to its template DNA strand. Transcribed RNA strand separates from its DNA template strand. The rate of replication is typically 20 times faster than transcription and six or more replication forks may be present at the same time on the chromosome.

What is CTD in transcription?

The carboxy-terminal domain (CTD) of RNA polymerase II is that portion of the polymerase that is involved in the initiation of DNA transcription, the capping of the RNA transcript, and attachment to the spliceosome for RNA splicing.

What comes first replication or transcription?

As with DNA replication, partial unwinding of the double helix must occur before transcription can take place, and it is the RNA polymerase enzymes that catalyze this process. Unlike DNA replication, in which both strands are copied, only one strand is transcribed.

Does transcription occur after replication?

Steps of DNA Transcription Transcription and DNA replication both involve making copies of the DNA in a cell. Transcription copies the DNA into RNA, while replication makes another copy of DNA.

Is DNA replication and transcription the same?

DNA replication is the process of making two daughter strand where each daughter strand contains half of the original DNA double helix. Transcription is the process of synthesis of RNA using DNA as a template.

How long does it take between transcription and translation?

Remember that in eukaryotes, transcription and translation are spatially segregated, with transcription taking place in the nucleus and translation in the cytoplasm. Introns are excised from transcripts prior to translation taking about 5-10 minutes on average for this process of mRNA splicing (BNID 105568).

How long does it take to transcribe?

Transcription Speed for the Average Person The average person can transcribe one audio hour in about 4 hours. It takes most people about one hour to transcribe 15 minutes of a clear, slow audio file. If any of the factors we mentioned above change the quality of the recording, that time might go up.

What is the role of TFIIH?

TFIIH is a multifunctional complex composed of 10 subunits, with an essential role in transcription, in which it functions in promoter opening, RNA polymerase II (RNAPII) phosphorylation, and promoter escape; this along with a central role in NER by promoting damaged strand discrimination, DNA opening, and endonuclease …

What produces a double stranded molecule?

Double-stranded DNA consists of two polynucleotide chains whose nitrogenous bases are connected by hydrogen bonds. Within this arrangement, each strand mirrors the other as a result of the anti-parallel orientation of the sugar-phosphate backbones, as well as the complementary nature of the A-T and C-G base pairing.

Where does replication transcription and translation take place?

Replication copies DNA; transcription uses DNA to make complementary RNAs; translation uses mRNAs to make proteins. In eukaryotic cells, replication and transcription take place within the nucleus while translation takes place in the cytoplasm.

What are the requirements for Double-Take replication?

For Double-Take Replication to take place, you must have the following requirements: Double-Take Availability installed on the Source Server Double-Take Availability installed on the Target Server A License key for the Source Server The DTMU Configurator installed on the Target Server Manual Server Installation

How do I install double-take availability?

To install Double-Take Availability, you can use the below instructions: Log into one of your Source or Target servers to be used in replication and download the Double-Take Availability executable.

What is the double-takequeue folder?

Queue Folder: You can browse to a folder to designate as the Double-TakeQueue Folder. This will be the folder where to buffer replicated data during periods of high replica traffic. It is best practices to set this folder on a disk that is not the root disk.

What happens during the S phase of DNA replication?

During the S phase (S from synthesis), before cell division, DNA replication and control for errors of DNA takes place. Replication begins with local decondensation and separation of the double DNA helices, so that the DNA molecule becomesaccessible for enzymes that make a complementary copy of each strand.
