3 mechanisms of microevolution - natural selection, genetic drift, gene flow 3 modifications made during RNA processing - - adenines added to poly-A tail - 5' end recieves a guanine cap - RNA splicing 3 steps of DNA replication - initiation, elongation, termination active transport - movement of molecules across a plasma membrane against from low concentration to high concentration with the expenditure of energy (ATP) by the cell adhesion - An attraction between molecules of different su...

MCAT General Chemistry | Latest Update | 2024/2025 | Already Passed What is the role of the conjugate base in an acid-base reaction, and how does it influence the reaction equilibrium? The conjugate base is formed when an acid donates a proton. It influences the reaction equilibrium by interacting with the acid, shifting the equilibrium based on the relative strengths of the acid and its conjugate base. How does the presence of a common ion affect the solubility of a salt in a solu...

EXSC 330 - Exam 1 Questions and Answers Latest Update Graded A+ **What is ATP (adenosine triphosphate) and its function in cells?** - ATP is the main energy source used by cells for most of their work. It stores potential energy extracted from food in its bonds, and energy is released when the outermost phosphate bond is broken by the enzyme ATPase. **What forms ADP in the ATP cycle?** - ADP forms when ATP combines with water (H2O). **What is the Phosphocreatine (PCr) system?** - The...

How does information flow? From DNA to RNA to protein What information is central to modern biotechnology? The use of methods to study and manipulate information about the central dogma. What is the exception to the central dogma? The transcription of RNA into DNA using reverse transcriptase. How does the cycle of the central dogma work? Instructions of DNA are transcribed onto messenger RNA. The ribosomes are able to read the genetic information inscribed on a strange of the ...

When naming carboxylic acids correct answers find the longest continuous carbon atom chain contianing the carboxylic acid group What is the prefix in carboxylic acids? correct answers -oate To name an ester, correct answers identify the alkyl group that is in the 'alcohol' portion of the molecule and name it; then identify the acid part of the molecule. The ester is named with the alkyl part first, and the acid part is named as a carboxylate. The terms ortho, meta, and para are used w...

BIO 441A EXAM 3 STUDY GUIDE WITH COMPLETE SOLUTION. LECTURE ONE - METABOLISM INTRODUCTION ● Autotrophs synthesize all their own cellular constituents from simple molecules ● Heterotrophs obtain energy through oxidation of organic compounds and therefore rely on autotrophs ● Metabolism involves many reactions such as ○ Glycolysis/gluconeogenesis ○ The citric acid cycle ○ Oxidative phosphorylation ● Catabolism is the degradation of biomolecules ○ Energy rich nutrients are...
