Back

thymine

Front

Back

deoxyribose sugar and phosphate

Front

Back

hydrogen bonds

Front

Back

hydrogen bonds

Front

Why is it crucial that living things are able to replicate their DNA?

Back

Each cell must have its own DNA

Front

Order of replication: 3, 4, 2, 1, 3, 1, 4, 2, 2, 1, 4, 3, 3, 4, 1, 2
