Answer:
DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific sequences of nucleotides. In order to be implemented, the instructions contained within genes must be expressed, or copied into a form that can be used by cells to produce the proteins needed to support life.
A trisomy is a condition in which there is one more chromosome than normal, meaning that in humans there are three replicates of a particular chromosome, instead of the normal pair of two. In most of the times, trisomies lead to miscarriages. In rare cases, it can lead to live birth but it will be associated with shortened life expectancy and disabilities. In humans, autosomal chromosomes are essential to life and an abnormal increase of their number can be lethal. The fetus will not be able to develop properly and this will lead to a miscarriage.
