Module 1: BIOD 102/ BIOD102 (Latest 2025/ 2026 Update) Essential Biology II W/Lab | Questions & Answers| Grade A| 100% Correct (Verified Solutions)- Portage Learning QUESTION What is a triplet code? Answer: A triplet code is a non-overlapping reading frame in which three bases encode for a single amino acid QUESTION The lagging strand must be replicated in a series of fragments called ____________. Answer: Okazaki fragments QUESTION True or False; If false, explain why the statement is false: Selective degradation is a form of post-transcription regulation. Answer: False; Selective degradation is a form of post-translation regulation QUESTION Which modification to pre-mRNA involves the addition of a guanine nucleotide that has been modified by the attachment of phosphates? Answer: 5' cap QUESTION The precise sequence of genetic information is called the ______, while observable characteristics are collectively known as a ________. Answer: genotype; phenotype QUESTION Which of the following is not one of the steps involved in the termination of translation? a. Disassembly of the translation initiation complex b. Binding of a releasing factor c. Ribosomal subunit binds to mature mRNA d. Liberation of completed polypeptide chain Answer: c QUESTION During the elongation phase of transcription, in what direction does the RNA polymerase glide across the DNA? Answer: 5' -- 3' QUESTION Which enzyme untwists and separates the helix parent strands at the replication fork? Answer: Helicase QUESTION Which type of RNA is synthesized from a complementary DNA strand and contains the exact sequence of DNA that dictates "how" to build a protein? Answer: mRNA QUESTION How do acetylation and methylation of histone proteins act as an "on"/"off switch of transcription? Your Answer: Answer: Acetylation, which is the addition of acetyl groups to an amino acid of the histone (within chromatin) tail, flips the switch "on", inducing transcription. Methylation, which is the addition of methyl groups to the amino acid of the histone tail, flips the switch "off", inhibiting transcription QUESTION Germ cells contain a specialized enzyme called ________ that facilitates the lengthening of telomeres.

Abstract
This academic examination document presents a comprehensive set of fifty (50) multiple-choice
questions designed for Module 1 of BIOD 102 (Essential Biology II with Lab) at Portage Learning.
The questions span five core thematic areas: cell structure and membrane dynamics, cellular
metabolism including enzymes, photosynthesis, and respiration, cell division and genetics
fundamentals, laboratory techniques and safety protocols, and integrative applications of cellular
processes in biological systems. Cognitive levels are distributed across recall (approximately 30%),
application (approximately 50%), and analysis (approximately 20%) to reflect a rigorous
introductory undergraduate biology assessment. Approximately 75% of questions are
scenario-based, placing biological concepts within laboratory, clinical, ecological, and real-world
contexts. Distractors are designed to address common student misconceptions, including
misapplied cellular processes, incorrect metabolic pathway identification, oversimplified genetic
predictions, microscopy misinterpretation, and unit conversion errors. Each question is
accompanied by a verified correct answer and a detailed rationale explaining the biological
principle and highlighting frequent errors. This resource serves as a study guide aligned with the
AAC&U VALUE rubric for scientific literacy and Portage Learning curriculum standards for the
2025-2026 academic year.

Many students don't have the time to work on their academic papers due to balancing with other responsibilities, for example, part-time work. I can relate.

kindly don't hesitate to contact me, my study guides, notes and exams or test banks, are 100% graded
