Models are used to stimulate reality and make predictions
Active transport requires energy because it moves molecules across a membrane to a region of lower to higher concentration which is often against their concentration gradient or has an obstructing factor.
In DNA, there is a code for the sequence
of three bases for the placement of certain amino acid in a protein chain.<span> The amino acid chain that can be produced by
the DNA base sequence of C-A-A-G-T-T-A-A-A-T-T-A-T-T-G-T-G-A would be based on
the DNA code CAA is valine, GTT is glutamine, AAA is phenylalanine, TTA is asparagine,
TTG is asparagine and TGA is threonine. </span>
