Answer 1

Binding of a ligand to a nuclear steroid receptor typically results in a change in gene expression, impacting the levels of specific proteins produced within the cell.

Step-by-step explanation:

When a ligand binds to a steroid receptor located in the nucleus, the cell's likely response is a change in gene expression. Steroid receptors act as transcription factors that directly interact with the cell's DNA, influencing the transcription of specific genes. This process results in the increased or decreased production of mRNA and consequently alters the synthesis of proteins that carry out various functions within the cell.When a ligand binds to a steroid receptor located in the nucleus, it initiates a series of events that ultimately lead to a change in gene expression.

The ligand-receptor complex enters the nucleus and interacts with the cell's DNA, which affects how genes are transcribed and translated into proteins. This can either enhance or silence the transcription of specific genes, resulting in the synthesis of different proteins.
