Attempt the Quiz - Fertilization

Here are a few simple Quiz questions that relate to Fertilization from the lecture and practical.

@@ Line 26: / Line 26: @@
 || Separation of the sperm from semen is not essential for successful fertilization to occur.
-{In a dividing cell, the replication of DNA occurs during:
+{Fertilization commences when a spermatozoon makes contact with an oocyte and ends:
 |type="()"}
-+ interphase
++ with the intermingling of maternal and paternal chromosomes at metaphase of the first cleavage division
-- prophase
+- when the spermatozoon is completely taken into the ootid
-- metaphase
+- when the spermatozoa penetrates the zona pellucida
-- anaphase
+- with the formation of the second polar body
-- telophase
+- all of the above
-|| Dividing cells replicate their DNA during interphase S phase, before any of the M phase stages. ({{mitosis}})
+|| Fertilization commences when a spermatozoon makes contact with an oocyte and ends with the intermingling of maternal and paternal chromosomes at metaphase of the first cleavage division.
-{Which of the following would be the most common karyotype for Turner's Syndrome:
+{Transport of sperm through the cervix is assisted by all of the following except:
 |type="()"}
-- 44,XX
++ capacitation of the sperm
-+ 45,X
+- the time of the female cycle
-- 44,XY
+- properties of the cervical mucus
-- 47,XXY
+- contractile activity of the uterus
-- 46,XX
+- pH
-|| Turner's Syndrome (45,X or 45,X0) is a form of {{monosomy}} associated with either a missing or altered second X chromosome.
+|| Capacitation of the spermatozoa modifies the glycoprotein coat and seminal proteins, the spermatozoa are already motile before capacitation, and therefore capacitation does not assist transport of sperm through the cervix.
