How is dna read and made, from what end to what end?
diamong [38]
Think of DNA as a code and think of your brain as a computer. Computers must have code to tell them what to do! Without DNA, we wouldn’t be able to function! People who are missing some “code” aka a strand of DNA may have some disabilities such as blindness. This is because their brain doesn’t known what to do with their eyes because they don’t have “code” to tell them what to do!

Hope that this helped.
