CF is a recessive type of disorder which means that both parents must carry the gene in order for the child to inherit the disease. If the child only inherits 1 copy of the affected gene, then the child becomes a carrier. Carriers do not manifests symptoms of the disease but they can pass the disease to their children.
With both parents as carriers, they will have the following chances: 50% carrier children, 25% affected child, and 25% normal child.
Answer:
All of them seems true tho
Answer:
Promoter.
Explanation:
It is promoter because Promoter is a DNA sequence where's the gene transcription begins. It is the
DNA sequence which RNA polymerase binds or join to
so as to begin transcriptionn of a gene . It is a region where the regulatory elements i.e protein will bind to and the Promoter sequences are found directly upstream or at the end of 5' of the transcription initiation site. This can also encode RNA such as mRNA, trans and so on.
The answer is D.) the process where distribution of molecules is balanced out by their movement.
