Multiple Choice

Which of the following best describes the events that take place when the first sperm binds to the oocyte?

• A)The head of the sperm is transported into the cytoplasm of the oocyte, where the nucleus of the sperm releases its DNA to combine with the DNA of the oocyte and transcription occurs. The oocyte then undergoes the second meiotic division.
• B)The entire sperm is transported into the cytoplasm of the oocyte, where the nucleus of the sperm releases its DNA to combine with the DNA of the oocyte and transcription occurs. The oocyte then undergoes the second meiotic division.
• C)The head of the sperm is transported into the cytoplasm of the oocyte, where the nucleus of the sperm releases its DNA to combine with the DNA of the oocyte and transcription occurs. The oocyte then undergoes the first meiotic division.
• D)The head of the sperm is transported into the cytoplasm of the oocyte which stimulates the completion of its arrested meiosis II and the second polar body is produced. The two parental (haploid)pronuclei then replicate their DNA while migrating towards each other to create their first mitotic division.
• E)The entire sperm is transported into the cytoplasm of the oocyte, where the nucleus of the sperm releases its DNA to combine with the DNA of the oocyte and replication occurs. The oocyte then undergoes the first meiotic division.
