1. Amniocentesis deals with patterns of ______ in the amniotic fluid.

• A. Fingers
• B. DNA
• C. Chromosomes
• D. Proteins

Correct answer: C

Rationale: Amniocentesis is a prenatal test that involves examining chromosomes in the amniotic fluid to detect genetic abnormalities. Therefore, the correct answer is 'Chromosomes.' The other choices, such as 'Fingers,' 'DNA,' and 'Proteins,' do not accurately represent what is analyzed during an amniocentesis procedure and are unrelated to the genetic information obtained through this test.

2. What does the umbilical cord contain?

• A. Pluripotent stem cells
• B. Cord blood stem cells
• C. Blood stem cells
• D. None of the above

Correct answer: B

Rationale: The correct answer is B: Cord blood stem cells. The umbilical cord contains stem cells that are found in cord blood, known as cord blood stem cells. These stem cells have the potential to develop into various types of cells and are used in medical treatments. Pluripotent stem cells are typically found in embryos and have the ability to develop into any type of cell in the body, not specifically in the umbilical cord. Choice C, blood stem cells, is a vague term that does not specifically refer to the stem cells found in the umbilical cord. Choice D is incorrect as the umbilical cord does contain cord blood stem cells.

3. Which of the following is included in a gynecological examination?

• A. Abdominal examination
• B. General and systemic examination
• C. Obstetric exam
• D. Pelvic examination

Correct answer: A

Rationale: Correct! A gynecological examination typically includes an abdominal examination to assess the overall health of the patient. This includes checking for any abnormalities, tenderness, or masses. General and systemic examinations are also important as they provide valuable information about the patient's overall health status. Pelvic examination is another essential component of a gynecological exam to assess the reproductive organs. Obstetric exams, focusing on pregnant women, are not part of routine gynecological examinations.

4. A solid ball of 12-16 cells having undergone mitotic division after fertilization is:

• A. Zygote
• B. Blastomere
• C. Morula
• D. Blastocyst

Correct answer: C

Rationale: A morula is a stage in embryonic development where a solid ball of 12-16 cells is formed after several rounds of mitotic division following fertilization. The zygote is the initial cell formed by the fusion of sperm and egg. Blastomere refers to individual cells in a developing embryo. A blastocyst is a later stage where a fluid-filled cavity forms within the embryo. Therefore, the correct answer is 'Morula.'

5. How many autosomes does a human primary spermatocyte have?

• A. 34
• B. 44
• C. 54
• D. 33

Correct answer: B

Rationale: A human primary spermatocyte has 44 autosomes. Autosomes are chromosomes that are not involved in determining an individual's sex. In humans, there are a total of 46 chromosomes in a somatic cell, with 22 pairs of autosomes and one pair of sex chromosomes. Therefore, the correct answer is 44 autosomes, making choice B the correct answer. Choices A, C, and D are incorrect as they do not represent the accurate number of autosomes in a human primary spermatocyte.
