An original section of dna has the base sequence agcgttaccgt. a mutation in this dna strand results in the base sequence aggcgttaccgt. this change represents a point mutation a silent mutation frameshift mutation a missense mutation

How can a mutation in a DNA base sequence cause a change in a trait?

Wetlands form where water and land meet. a lake with a wetland fringe can fill in with decayed plant and animal material to become a wet meadow. a pond can fill in to become a bog or fen. sediment can fill in a river marsh to become a swamp.flooding of coastal lowlands from rising sea levels has created broad coastal marshes that are protected from wave action by barrier islands or reefs. coastal wetlands also form when rivers deposit sediment as they reach the ocean. plants then take root and hold the soil firm against the forces of tides and waves.
