The nurse is explaining to a client how genes express certain genetic traits. Which of the following explanations is correct?
1. Every cell contains the individual's entire genome, but each gene is not expressed by each cell.
2. Every cell contains 46 chromosomes, and when sugar and phosphates attach to the cell, each chromosome is expressed.
3. Every cell contains active and inactive DNA, and active DNA in each gene controls the cell's activity.
4. Every cell contains 23 pairs of chromosomes, and each gene is expressed by interaction with the cell's building blocks A, C, G, and T.
Every cell contains the individual's entire genome, but each gene is not expressed by each cell.
Rationale: Every cell contains the individual's entire genome, but each cell does not express each gene. As cells specify, they develop different coding and act differently to make up all the different organs and cells in the body. Sugar and phosphates do not cause expression of the cell. A, C, G, and T make up the chromosomes within the nucleus. Expression of the cell occurs with mRNA (not DNA), which is decoded to produce a protein designated by a gene.
