Question 1 of 5
Identify the fluid that is least possible to transmit AIDS.
Correct Answer: D
Rationale: The correct answer is D: Saliva. Saliva has very low levels of HIV, making it least likely to transmit AIDS. HIV transmission requires direct contact with infected bodily fluids containing high viral loads, such as blood, breast milk, and semen. Saliva does not typically contain enough HIV to transmit the virus, as it has enzymes that can inhibit HIV. Therefore, the risk of HIV transmission through saliva is extremely low compared to the other fluids listed.
Question 2 of 5
In reference to the flow diagram below respond to the following question. The annotation A refers to which sites
Correct Answer: C
Rationale: The correct answer is C: Restriction. In a flow diagram, the annotation "Restriction" likely indicates the site where a DNA molecule is being cut by a restriction enzyme. This process is essential in molecular biology for DNA manipulation. Choice A: Annealing involves the process of complementary DNA strands coming together, usually during PCR or hybridization. Choice B: Melting refers to the separation of double-stranded DNA into single strands, often seen in denaturation steps. Choice D: RNAse is an enzyme that specifically degrades RNA molecules, not involved in the DNA manipulation processes indicated in the diagram.
Question 3 of 5
A segment of DNA that reads the same from forward and backward is called_____.
Correct Answer: B
Rationale: The correct answer is B: Palindromic DNA. Palindromic DNA refers to a segment of DNA that reads the same from both directions. This property occurs when the nucleotide sequence on one strand of DNA is the reverse complement of the nucleotide sequence on the other strand. This symmetry allows the DNA sequence to be read the same forward and backward. Incorrect choices: A: Complementary DNA - Complementary DNA refers to a synthesized DNA strand that is complementary to a given DNA sequence. C: Copy DNA - Copy DNA is not a commonly used term in molecular biology. D: Transcribed DNA - Transcribed DNA refers to DNA that has been converted into RNA through the process of transcription, not DNA that reads the same forward and backward.
