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.
Cells spend 90 percent of their time in interphase, during which the cell grows, produces proteins, replicates DNA and prepares for mitosis. As with the remainder of the cell cycle, these processes occur in stages, not all at once. Interphase is divided into three main stages: G1, S and G2. During the S phase of interphase, which follows G1, all of the chromosomes are replicated. After replication, each cell now consists of two sister chromatids. Although the actual amount of DNA doubles, its ploidy, the chromosome count, remains the same.
