The main molecule found in nucleus is called DNA(deoxyribonucleic acid). This molecule is made of subunits called nucleotides. A nucleotide is made of a nitrogenous base that can be adenine, thymine, guanine or cytosine; a five carbon sugar called deoxyribose and a phosphate group. This molecule controns protein synthesis. Proteins are crucial to the cell's function.

Can someone please help me with this ap biology problem! I would really appreciate it:)
strojnjashka [21]

Answer:

D - the production of a specific mRNA will increase as a result of the binding of the hormone receptor complex to the DNA

Explanation:

We are told that the hormone binds a receptor and then enters the cell, binding to the DNA and promoting transcription of a specific gene.

Transcription is the process whereby mRNA molecules are synthesised from a DNA sequence, which are then translated into specific process. D is correct, as the gene the hormone binds to will increase in transcription, producing a specific mRNA.

A, B and C are much more general processes, not linked to the actions of a hormone on a specific gene.
