Living with a roommate can dramatically reduce the cost of attending law school and potentially have a measurable effect on student loan debt. For example: A student living alone paying $800 rent and $100 in utilities can reduce their cost by $450 per month by sharing expenses with a roommate.
The tetrad is a structure that only exists during the late stages of Prophase I and early stages of Metaphase I in Mieosis I. Prior to being sent off to different cells, the h â¦ omologous chromosomes clump together in these units called tetrads consisting of 2 chromosomes and 4 chromatids. Corresponding parts of the 2 homologous chromosomes are able to switch with each other during this state in a process known as crossing over.
There should be 23 tetrads in a human cell at the beginning of meiosis. The cell then divides twice with the chromatids separating each time. This results in four cells each of which contains 23 chromosomes (46/2). These cells are called gametes. When one gamete combines with another gamete, a zygote is formed which has 46 chromosomes. The zygote then goes through mitosis to form more cells with 46 chromosomes and those cells make up the embryo.
