It is DNA's clever structure that allows it to contain millions of instructions in a small space. DNA is built in adouble helix. An easy way to picture a double helix is to picture a ladder, now grab either end of the ladder and twist! The spiraled shape you've made is a double ...
The double helix shape of DNA makesDNA replicationpossible. In replication, DNA makes a copy of itself in order to pass genetic information on to newly formeddaughter cells. In order for replication to take place, the DNA must unwind to allow cell replication machinery to copy each strand. Ea...
