What happens right after trasncription ends?
After transcription ends, the newly synthesized mRNA undergoes several processing steps, including the addition of a 5' cap and a poly-A tail, and splicing to remove introns. This processed mRNA is then transported from the nucleus to the cytoplasm, where it will be translated into a protein by ribosomes. In prokaryotes, transcription and translation occur simultaneously in the cytoplasm, as there is no nuclear membrane to separate the processes.
What happens right after tanscription ends?
After transcription ends, the newly synthesized RNA molecule undergoes processing. In eukaryotes, this includes capping at the 5' end, addition of a poly-A tail at the 3' end, and splicing to remove introns. The mature mRNA is then transported from the nucleus to the cytoplasm, where it can be translated into proteins. In prokaryotes, the process is more direct, as transcription and translation can occur simultaneously without extensive RNA processing.
What happens when a steroid hormonoe binds to a receptor?
acts as a transcription factor and binds to DNA, activating a gene
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.
Why does transcription need to be controlled?
Transcription needs to be controlled to regulate gene expression in response to cellular signals and environmental conditions. This control allows the cell to produce the right proteins at the right time in the right amount, ensuring proper cell function and maintaining homeostasis. Overactive or underactive transcription can lead to diseases and developmental abnormalities.
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.

The DNA double helix unwinds.
What is the significance of the 3' and 5' ends in DNA replication and transcription processes?
The 3' and 5' ends in DNA replication and transcription processes are significant because they determine the direction in which DNA is synthesized. In DNA replication, the new strand is synthesized in the 5' to 3' direction, while in transcription, the RNA molecule is synthesized in the 5' to 3' direction based on the template DNA strand. This directional synthesis is crucial for maintaining the genetic information and ensuring accurate replication and transcription processes.

What is the significance of the 5 prime and 3 prime ends in DNA replication and transcription processes?
The 5' and 3' ends of DNA are important in replication and transcription because they determine the direction in which the genetic information is read and copied. The 5' end is where new nucleotides are added during replication and transcription, while the 3' end is where the process starts. This directional specificity ensures accurate copying and expression of genetic information.
Does splicing occur during transcription?
No, splicing does not occur during transcription. Splicing is a process that happens after transcription, where non-coding regions of the RNA molecule are removed and the coding regions are joined together to form the final mRNA molecule.
Why does transcription need to be controlled?
Transcription needs to be controlled to regulate gene expression in response to cellular signals and environmental conditions. This control allows the cell to produce the right proteins at the right time in the right amount, ensuring proper cell function and maintaining homeostasis. Overactive or underactive transcription can lead to diseases and developmental abnormalities.
What happens at the of transcription?
The transcription process stops.mRNA detaches and moves to the ribosomesTranscription is the first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme RNA polymerase.
