Webbing of the digits, or syndactyly, is not caused by the fingers sticking together in the womb; rather, it is caused by failure, during the sixth to eighth weeks of intrauterine life, of the usual longitudinal interdigital necrosis that normally separates the fingers.ebbing of the digits, or syndactyly, is not caused by the fingers sticking together in the womb; rather, it is caused by failure, during the sixth to eighth weeks of intrauterine life, of the usual longitudinal interdigital necrosis that normally separates the fingers.
Oct 28, 2015. During Mitosis, DNA is replicated during the S phase (Synthesis phase) of Interphase. Interphase is basically the daily life cycle of the cell. Cells spend most of their life in Interphase before Mitosis occurs. Precise and careful DNA replication is very important in the prevention of genetic abnormalities that can lead to diseases or, in worse cases, death.
DNA has to replicate before mitosis to keep the number of chromosomes and DNA in the cell consistent. Mitosis is the process of reproducing cells by splitting one cell in half â¦ to make two.If the DNA didn't replicate, the two daughter cells wouldn't be able to have a complete strand.DNA replicates by dividing in half, then creating a mirror image of itself.NA replication mus occur before mitosis starts. Mitosis is another  word for cell division and so there must be two copies of DNA for  each cell at the end stage.
