Verified answer
The transcription process stops.
mRNA detaches and moves to the ribosomes
Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase.

∙ 8y agoThere are three main steps to the process of DNA transcription.
1.RNA Polymerase Binds to DNA RNA polymerase attaches to the DNA at a specific area called the promoter region. 2.Elongation
Certain proteins called transcription factors unwind the DNA strand and allow RNA polymerase to transcribe into a single stranded RNA polymer called messenger RNA (mRNA). RNA is composed of nucleotide bases. RNA however, contains the nucleotides adenine, guanine, cytosine, and uracil (U). When RNA polymerase transcribes the DNA, guanine pairs with cytosine and adenine pairs with uracil.3. Termination
RNA polymerase moves along the DNA until it reaches a terminator sequence and detaches from the DNA.

Difference between DNA replication and transcription?
1. Replication is the duplication of two-strands of DNA. Transcription is the formation of single, identical RNA from the two-stranded DNA. 2. There are different proteins involved in replication and transcription. 3. In replication, the end result is two daughter cells, while in transcription, the end result is a protein molecule. 4. In transcription, DNA serves as the template for RNA synthesis.
Which direction does transcription take place?
in DNA transcription occurs from the 5' end to the 3' end
What best describes the product of transcription?
Transcription is the second part of the Central Dogma of biology: DNA to RNA to Protein. At the end of transcription, there is an RNA copy of the DNA segment that has been spliced so that it only contains the coding sequences for the gene. That is then exported for translation. This segment, the direct project of transcription is messenger RNA or mRNA.
What determines where on the DNA molecule transcription begins and ends?
An RNA primer will attach to the unzipped DNA molecule signaling the beginning of transcription and transcription will occur until the DNA molecule is completely copied (the end is when there is no more DNA molecule to replicate).
When DNA is transcribed the product is?
DNA transcription is a process of converting genetic information from DNA to RNA. The RNA may be used to produce proteins if that is what the DNA coded for. In this case, the RNA is called mRNA and the RNA molecule is called a transcription unit. So that would be one answer to this question. ( The process by which the RNA becomes a protein is called translation) Sometimes the DNA does not code for a protein. In these cases the RNA may end up being ribosomal RNA or transfer RNA. These are also possible answers. A general answer might be an RNA molecule corresponding to the DNA molecule that is being transcribed. So the answer is an equivalent RNA sequence for that particular DNA sequence.

What are the end results in transcription and translation?
Transcription yields a strand of messenger RNA, which then goes to the ribosomes, where it undergoes translation by transfer RNA, and the absolute end result is a protein.

What happens right after the end of transcription?
After transcription, the mRNA produced is modified through processes like capping and polyadenylation. This modified mRNA then leaves the nucleus and enters the cytoplasm where it can be translated into a protein by ribosomes.

What is made in transcription?
mRNA is made. Messenger (Ribose Nucleic-Acid). mRNA is a single strand of RNA made from the template strand of DNA. The mRNA is a exact copy of the coding or sense strand of DNA. The only difference between the produced RNA and DNA is the DNA has deoxyribose as its backbone sugar, and all Thymines have are replaced with Uracil.
What happens first during transcription?
RNA polymerase reaches the beginning of the gene

What is the step of protein synthesis that occurs in the nucleus?
The step of protein synthesis that occurs in the nucleus is transcription. Transcription is the process of copying the genetic code from DNA into RNA. The RNA molecule that is produced during transcription is called messenger RNA (mRNA). mRNA then travels to the cytoplasm, where it is translated into a protein. In transcription, the DNA double helix opens up at a specific location called the promoter. A protein called RNA polymerase binds to the promoter and begins to move along the DNA strand, unzipping the helix as it goes. RNA polymerase then uses the exposed DNA strand as a template to synthesize a complementary RNA strand. This RNA strand is the mRNA molecule. Once the mRNA molecule is complete, it separates from the DNA and travels to the cytoplasm. In the cytoplasm, the mRNA molecule binds to a ribosome. The ribosome then reads the mRNA molecule and uses the information to assemble a protein molecule. The protein molecule is then released from the ribosome and can go on to perform its function in the cell. Here are the steps of transcription in detail: Initiation: RNA polymerase binds to the promoter region of DNA. Elongation: RNA polymerase moves along the DNA strand, unzipping the helix and synthesizing a complementary RNA strand. Termination: RNA polymerase reaches a termination sequence in the DNA and stops synthesizing RNA. The mRNA molecule that is produced during transcription is a single-stranded molecule that contains the same information as the original DNA strand. However, the mRNA molecule is modified in a few ways. First, the 5' end of the mRNA molecule is capped with a group of nucleotides called a 5' cap. The 5' cap helps to protect the mRNA molecule from degradation and helps it to bind to the ribosome. Second, the 3' end of the mRNA molecule is polyadenylated, which means that it is added to a long chain of adenine nucleotides. The polyadenylation tail helps to stabilize the mRNA molecule and helps it to be transported to the cytoplasm. Transcription is a complex process that is essential for protein synthesis. It is the first step in the process of converting genetic information into a functional protein molecule.
