A full set of sister chromatids is created during the synthesis (S) phase of interphase, when all the chromosomes in a cell are replicated. Sister chromatids are two identical copies of the same chromosome formed by DNA replication, attached to each other by a structure called the centromere. During cell…
Silicon is widely used in solar panels production since it can be easily produced from the sand. Generally, silicon behaves like an insulator – it contains no freely moving electrons. Semiconductors are placed between conductors and insulators. This means that depending on the environment, semiconductors can act either like a…
