Answer:
They act to regulate the expression of specific genes (androgen-responsive)
Explanation:
Testosterone is a reproductive hormone in male humans. Testosterone as well as its closely related hormones e.g dihydrotestosterone, all belong to a class of hormones called "Androgens".
Androgens operate by entering into a cell and binds with specific androgen-receptor proteins (AR proteins). This contact activates the AR proteins, forming an androgen-receptor complex.
This complex then translocates into the nucleus of specific cells to bind to the DNA. Once it binds, it either inhibits or promotes the expression of specific genes (androgen-responsive). Hence, AR proteins are transcription factors because they play a significant role in regulating transcription of specific genes i.e. turning 'on' or 'off' of specific genes.
This process helps to direct the development of male sexual characteristics.
The answer would be 12 hope this helped
Answer:
Mutation is a alteration in the DNA sequence in a gene during cell divison iwhere gene is coded mitakeny or due to the error. Mutatio is a random process as it can not be determind or known befor bthechange in sequence what gene or DNA would be effected by it or what genes would be transfer from the parents.
Natural selection is a process where some of the traits that are helpful in the surviving and increasing the number of individuals in a population and transfer from one generation to other according the adaption and change over the long timeline. Thus, it is not random and based on the traits that are helpful in a environment or for the survival of
Answer:
Explanation:
Polarity of amino acids affects how they interacts. Amino acids such as valine, methionine, and alanine are nonpolar while serine, threonine, and cysteine are polar which mean they are hydrophilic this determines how the react.
The structure and the shape of amino acid also determines how they react.
The bond form between amino acids also affects its interaction
