1. What type of genetic testing can reveal an individual's susceptibility to certain diseases?
- A. Karyotyping
- B. Pharmacogenomics
- C. Paternity testing
- D. Microarray analysis
Correct answer: D
Rationale: A) Karyotyping is a genetic test that examines an individual's chromosomes to detect abnormalities such as extra or missing chromosomes. It is not typically used to reveal an individual's susceptibility to certain diseases. B) Pharmacogenomics is the study of how genes affect a person's response to drugs. It focuses on how genetic variations can influence drug response, rather than susceptibility to diseases. C) Paternity testing is a genetic test used to determine the biological relationship between a child and an alleged father. It is not used to reveal an individual's susceptibility to diseases. D) Microarray analysis is a type of genetic testing that can reveal an individual's susceptibility to certain diseases by analyzing variations in their DNA. It can identify genetic markers associated with increased risk for specific conditions, allowing for personalized risk assessment and preventive measures.
2. What is the primary function of Bartholin's glands?
- A. Secretes hormones that help the body respond to stress
- B. Provide lubrication for the vagina
- C. Helps control growth and development of the body
- D. Stimulate the development of T cells
Correct answer: B
Rationale: Bartholin's glands are two small glands located on each side of the vaginal opening. Their primary function is to secrete fluids that help lubricate the vagina during sexual arousal. This lubrication helps to reduce friction and discomfort during sexual activity, making intercourse more comfortable and pleasurable. Choices A, C, and D are incorrect because Bartholin's glands do not secrete hormones to respond to stress, control growth and development, or stimulate the development of T cells. Their main role is specifically related to vaginal lubrication.
3. Which of the following is NOT a common route of transmission for a sexually transmitted infection (STI)?
- A. Unprotected sexual contact
- B. Sharing contaminated needles
- C. Deep kissing
- D. Mother to child during childbirth
Correct answer: C
Rationale: A) Unprotected sexual contact is a common route of transmission for sexually transmitted infections (STIs) as many STIs are spread through genital, anal, or oral sex without the use of barrier protection such as condoms. B) Sharing contaminated needles can also transmit STIs such as HIV and hepatitis B and C, especially among individuals who inject drugs. C) Deep kissing, while it can transmit certain infections like herpes simplex virus (HSV-1) or cytomegalovirus (CMV), is not a common route of transmission for most STIs. Although some STIs can be transmitted through saliva, deep kissing is not a primary mode of transmission for most STIs. D) Mother to child transmission during childbirth can occur with certain STIs such as HIV, syphilis, and herpes, where the infection can be passed from the mother to the baby during delivery. Therefore, deep kissing (option C) is the correct answer as it is not a typical route of transmission for most STIs.
4. What is the process of making copies of DNA called?
- A. Transcription
- B. Translation
- C. Replication
- D. DNA repair
Correct answer: C
Rationale: A) Transcription is the process of synthesizing RNA from a DNA template. It involves the creation of mRNA molecules from a DNA template. B) Translation is the process of synthesizing proteins from mRNA. During translation, the genetic code carried by mRNA is decoded to produce a specific sequence of amino acids, forming a protein. C) Replication is the process of making copies of DNA. This process occurs before cell division and ensures that each daughter cell receives an identical copy of the genetic material. D) DNA repair is a cellular mechanism that corrects errors in DNA that arise due to various factors such as exposure to mutagens or mistakes during DNA replication. It is essential for maintaining the integrity of the genetic material.
5. What is the relationship between work, force, and displacement?
- A. Work is directly proportional to force but inversely proportional to displacement
- B. Work is directly proportional to both force and displacement
- C. Work is inversely proportional to force but directly proportional to displacement
- D. Work is inversely proportional to both force and displacement
Correct answer: B
Rationale: Work is directly proportional to both force and displacement. The work done on an object is calculated by multiplying the force applied to the object by the distance the object moves in the direction of the force. Therefore, work is directly proportional to both force and displacement. Choice A is incorrect because work is not inversely proportional to displacement. Choice C is incorrect because work is not inversely proportional to force. Choice D is incorrect because work is not inversely proportional to both force and displacement.
