Answer:
A transcription factor that binds to a gene first and facilitates binding of other transcription factors is called an activator transcription factor.
Explanation:
Transcription factors are proteins that regulate the transcription of genes.Transcription is the process where a gene's DNA sequence is transcribed into an RNA molecule. Transcription is a key step in using information from a gene to make a protein.
The enzyme RNA polymerase, which makes a new RNA molecule from a DNA template, must attach to the DNA of the gene. It attaches at a spot called the promoter.In eukaryotes, RNA polymerase can attach to the promoter only with the help of basal (general) transcription factors. They are part of the cell's core transcription toolkit, needed for the transcription of any gene.
A typical transcription factor binds to DNA at a certain target sequence. Once it's bound, the transcription factor makes it either harder or easier for RNA polymerase to bind to the promoter of the gene.
Some transcription factors activate transcription, other transcription factors repress transcription.
cholecystokinin is the answer, good luck!
Answer:
the force needed to accelerate the 1000kg car by 3m/s2 is 3000N .
In this scenario, once in a target tissue, the water soluble hormones which is the answer would then bind to the intracellular receptors inside the cell membrane. Hope this is the right answer and would be of big help then.
Answer:
These 3 receptors are different from each other. They do differ from each other by their location and function.
1. Testosterone receptor : It is an Androgenic receptor
2. Ferrotransferrin receptor : It acts as an element-binding protein which is iron responsive.
3. Fibroblast growth factor : It acts as a growth factor.
Explanation:
1. Testosterone :
Location- Xq 11-12 in the X chromosome.
Function-
- maintains male skeletal integrity by osteoblast and osteocytes.
- maintains female sexual, somatic and behavior.
- develops male sexual characters.
2. Ferrotransferrin :
Location- chromosome 3q21
Function-
- intakes iron in the cell.
- maintains the cellular iron equilibrium.
- post-transcriptional modification.
3. Fibroblast (growth) :
Location- chromosome 4p16.3
Function-
- helps in bone development.
- helps in bone growth maintenance by ossification.
