Why does dna need to coppy before the cell divides

Describe your dna model. which part do the straws represent? the pushpins? the paper clips and the black dots you made with the marker?

Label the steps for protein synthesis in order, beginning with the first steponce the protein is made, the gene for a particular trait is expressedmrna joins the ribosome, and the anticodons from trna join mrna to form a chain ofamino acidsrna polymerase unzips dna and free rna nucleotides join dna to form mrnav a chain of amino acids is formed from peptide bonds, creating a proteinmrna is transported from the nucleus of the cell to the ribosomes of the cell.

If a checkpoint detects damaged dna, the checkpoint may
