Here is a snack made DNA model with the strand TAC GTA TGA. We used four different coloured marshmallows to represent T,A,C and G. We made the bonds ATG CAT ACT. We held the DNA model together using two liquorice sticks and 9 toothpicks.
DNA is self-replicating material that contains genetic information, which is passed on from the biological parents to their kid. You receive 23 chromosomes from your mom and 23 chromosomes from your dad which is equal to 64 chromosomes total. DNA contains the information for our body to know how to reproduce, develop and survive.
