Answer:
As a transcription factor
Explanation:
Testosterone is a male sex hormone secreted by the testicles which promote the growth of the male reproductive organs and the male characters like muscle buildup.
The hormone shows the paracrine effect and thus act on the target cell at distant. The mechanism of action of the testosterone is that it controls the gene expression of various other genes.
The testosterone binds the specific proteins which activate the expression of the gene that is they acts as a transcription factor which activates the expression.
Thus, as a transcription factor is correct.
The correct answer to your question is B. Glycine-Tyrosine-Glycine-Histidine-Histidine.
You can find this by taking groups of codons starting with the first group (GGC). GGC is located under Glycine so Glycine will therfore be an amino acid found in the protein. Continue doing this with the next codons to come up with the answer.
I hope this isn't too late and still helps!
