Growth factors, Morphogens & Transcription factors Watch
Growth factor - a substance, such as a vitamin or hormone, which is required for the stimulation of growth in living cells. (got this from internet)
Morphogens - a signalling molecule,..I guess it functions in the same way as a growth factor
rate of transcription of genes controlled by transcription factors
Transcription factors= proteins that bind to DNA & switch genes on/off to increase/decrease rate of transcription
There are 2 types of transcription factors: Activators-start transcription & Repressors-stop transcription
The attachment provides all these 3 terms and I am trying to see how they are all related and what differences there are between them.
In this attachment, it seems that they are indicating that morphogens and growth factors and transcription factors are the same thing.
Would really like any views on this
