The Biology Project is fun richly illustrated and tested on 1000s of students. As mentioned earlier haploid cells contain one set of chromosomes while diploid cells contain two sets.

Distinguish between the two instances of genetic variation.
. The menstrual cycle may be divided into two phases. Sexual reproduction requires fertilization the union of two cells from two individual organisms. Meiosis II results in the production of 4 haploid SPERMATIDS Maturation of the sperm occurs in the SEMINIFEROUS tubules.
Fill in the missing item in each sentence and then put the sentences in order showing the movement of sperm out of the body. Describe cellular events during meiosis. Menstruation is the cyclic orderly sloughing of the uterine lining in response to the interactions of hormones produced by the hypothalamus pituitary and ovaries.
DNA transcription is the process by which the genetic information contained within DNA is re-written into messenger RNA mRNA by RNA polymerase. Meiosis I ends with the production of SECONDARY spermatocytes the first haploid cells in the process. The Biology Project an interactive online resource for learning biology developed at The University of Arizona.
It has been designed for biology students at the college and high school level but is useful for medical students physicians science writers and all types of interested people. The length of a menstrual cycle is the number of days between the first day of. This mRNA then exits the nucleus where it acts as the basis for the translation of DNA.
1 follicular or proliferative phase and 2 the luteal or secretory phase. By controlling the production of mRNA within the nucleus the cell regulates the rate of gene expressionIn this article we will. Not all terms will be used.
