This is the law of dominance in genetics. The dominant allele will mask the effects of the
recessive allele and therefore will be the visible trait of the phenotype. Most often, the dominant allele codes for functional proteins, while the recessive does not code for functional proteins. Dominance in genetics is
significant in Mendelian inheritance.
MRNA it is the messenger, for it "feeds" information
Answer;
Insulin and the growth hormone
The hormones that are involved in building and maintaining healthy bone tissues are Insulin and growth hormone
Explanation;
Insulin has some anabolic properties for bone. It is uncertain whether insulin stimulates bone directly or indirectly by increasing muscle work and thus skeletal loading.
Growth hormone is a peptide hormone secreted from the pituitary gland under the control of hypothalamus. It directly and through IGF-I stimulates osteoblast proliferation and activity, promoting bone formation. Additionally it stimulates osteoclast differentiation and activity,promoting bone resorption.
Steroid hormones easily diffuse through the cell membrane. The hormone binds to its receptor in the cytosol, forming a receptor–hormone complex. The receptor–hormone complex then enters the nucleus and binds to the target gene on the DNA.
