1. Why are mitochondria and chloroplasts believed to have originated from endosymbiosis? (A) Because they are completely autonomous organelles that function independently of the nucleus. (B) Because they contain no genetic material of their own and rely entirely on the host genome. (C) Because their physical volume is significantly larger than that of typical prokaryotic bacteria. (D) Because they lack a lipid membrane and are directly exposed to the cytoplasmic environment. (E) Because they possess their own circular DNA and 70S ribosomes similar to those of prokaryotes.

2. In a family with an X-linked recessive disorder, if the father is unaffected and the mother is a carrier, what is the probability of the offspring being affected? (A) All offspring, regardless of gender, will manifest the disease phenotype. (B) Sons have a 50% chance of being affected, while all daughters will be phenotypically normal. (C) Both sons and daughters have an equal 50% probability of manifesting the disease. (D) Only daughters will manifest the disease, while all sons will be phenotypically normal. (E) All sons will manifest the disease, and all daughters will be carriers of the trait.

3. What is the functional similarity between prokaryotic Sigma factors and eukaryotic Transcription Factors? (A) Both possess the catalytic active site required for RNA synthesis. (B) Both must cross the nuclear envelope to bind DNA and regulate gene expression. (C) Both are primarily responsible for recognizing specific promoter sequences to recruit RNA polymerase. (D) Both are permanent subunits of the polymerase complex that remain bound during elongation. (E) Both possess helicase activity to continuously unwind the DNA double helix during transcription.

4. The Wobble Hypothesis primarily explains which of the following biological phenomena? (A) Each codon strictly corresponds to a unique tRNA with a fully complementary anticodon. (B) The start codon (AUG) allows non-standard pairing to accelerate ribosome assembly. (C) The ribosome undergoes a physical "wobble" conformation during translocation. (D) Cells can recognize all amino acid-coding codons with fewer than 61 types of tRNA. (E) The tRNA acceptor stem wobbles to prevent incorrect amino acid attachment.

5. Which of the following statements regarding the applications and techniques of proteomics is correct? (A) Western blotting utilizes labeled DNA probes to detect the presence of specific protein targets. (B) The proteome is defined as the total number of genes encoded within an organism's complete genome. (C) SDS-PAGE primarily separates protein molecules based on their intrinsic charge rather than their molecular weight. (D) Phage display technology can be employed to investigate interactions between proteins and other molecules. (E) Protein microarrays are limited to detecting the purity of isolated proteins rather than their functional activities.

6. Histone acetylation is generally associated with gene activation. What is the primary molecular mechanism underlying this phenomenon? (A) Acetylation neutralizes the positive charge on lysine residues, weakening the electrostatic attraction to the negatively charged DNA backbone and creating a more open chromatin structure. (B) The addition of acetyl groups increases hydrophobicity, thereby strengthening the Van der Waals forces between histones and DNA to stabilize the nucleosome. (C) Acetylation acts as an enzymatic cofactor that directly catalyzes the phosphorylation of RNA Polymerase II to initiate transcription elongation. (D) Acetyl marks specifically recruit DNA methyltransferases to promote CpG island methylation, effectively locking the gene in a silenced state. (E) Acetylation serves as an irreversible signal that targets histones for degradation via the ubiquitin-proteasome pathway, clearing the DNA for transcription.

7. What is the original evolutionary function of the CRISPR-Cas9 system in bacteria? (A) To serve as a mechanism for repairing spontaneous DNA mutations within the genome. (B) To regulate the expression of the bacteria's own metabolic genes during starvation. (C) To facilitate the conjugation process and horizontal gene transfer between bacteria. (D) To act as an adaptive immune system that memorizes and cleaves foreign DNA from phages. (E) To assist in the structural formation of endospores during extreme environmental stress.
