The DNA strand of bases is a template (model) for the replication of DNA



Each DNA strand is composed of a sequence of bases connected

Next, the mRNA is chopped up and removed, and the DNA strand is used to make



formed by hydrogen bond interaction of two separate DNA strands.



(DNA ligase is the same enzyme used to bond DNA strands together) DNA



The nitrogenous bases on the two strands of DNA pair up,



Deoxyribonucleic acid (DNA) consists of two sugar-phosphate strands forming



Deoxyribonucleic acid (DNA) consists of two sugar-phosphate strands forming



DNA that will base pair with the following strand of



Structure of DNA



This picture shows how DNA bases are stacked together along the double helix



DNA polymerase primes the strand, adds base pairs, and repairs damages



DNA and its building blocks.
