English Grammar
1. What is the best way to punctuate the dialogue "Are you coming?" she asked. "Maybe," I replied.
- A. "Are you coming?" she asked? "Maybe," I replied.
- B. "Are you coming?" she asked. "Maybe," I replied.
- C. "Are you coming?" she asked, "Maybe," I replied.
- D. "Are you coming?" she asked, "Maybe," I replied.
Correct answer: B
Rationale: Each speaker's words need quotation marks, and the question mark should go inside the closing quotation mark of the question.
2. What is a mutation?
- A. A change in the DNA sequence
- B. A type of protein
- C. A normal part of the DNA replication process
- D. A harmless variation in DNA
Correct answer: A
Rationale: Rationale: A mutation is defined as a change in the DNA sequence. Mutations can occur due to various factors such as errors during DNA replication, exposure to mutagens (e.g., chemicals, radiation), or spontaneous changes. These changes can result in alterations to the genetic information carried by an organism, which can have different effects ranging from harmless variations to causing genetic disorders or diseases. Mutations are a fundamental aspect of genetic diversity and evolution. Options B, C, and D do not accurately describe what a mutation is.
3. Identify the relative clause in the sentence "The book that won the award was a bestseller."
- A. "The book"
- B. "that won the award"
- C. "was a bestseller"
- D. "award"
Correct answer: B
Rationale: The relative clause "that won the award" provides additional information about the specific book.
4. What is the function of introns in eukaryotic genes?
- A. They code for protein sequences.
- B. They are involved in gene regulation.
- C. They are removed during mRNA processing.
- D. They are non-functional remnants of ancient DNA.
Correct answer: C
Rationale: Rationale: A) Introns do not code for protein sequences. Exons are the segments of DNA that code for proteins. B) While introns can indirectly influence gene regulation, their primary function is not directly involved in gene regulation. C) Introns are non-coding regions of DNA that are transcribed into pre-mRNA but are removed during mRNA processing through a process called splicing. This allows only the exons to be included in the mature mRNA that will be translated into proteins. D) While introns were once thought to be non-functional remnants of ancient DNA, research has shown that they can have regulatory functions and play a role in gene expression.
5. Which of the following is a characteristic of alkenes?
- A. They have a double bond between carbon atoms.
- B. They are saturated hydrocarbons.
- C. They contain only single bonds.
- D. They are derivatives of ammonia.
Correct answer: A
Rationale: Alkenes have a double bond between carbon atoms, making them unsaturated hydrocarbons. The other choices do not accurately describe alkenes.
6. What is the function of the Golgi apparatus?
- A. Breaking down and recycling cellular waste
- B. Packaging and transporting proteins and lipids
- C. Generating energy through cellular respiration
- D. Translating DNA into proteins
Correct answer: B
Rationale: The correct answer is B: Packaging and transporting proteins and lipids. The Golgi apparatus plays a crucial role in processing, packaging, and distributing proteins and lipids synthesized by the cell. It modifies these molecules and directs them to their appropriate destinations within the cell or for secretion outside the cell. This function is essential for maintaining the proper functioning of the cell and coordinating various cellular processes. Options A, C, and D are incorrect as they describe functions carried out by other cellular organelles, highlighting the specificity and importance of the Golgi apparatus in protein and lipid trafficking.
