Phospholipid bilayers are NOT stabilised by: a. van der Walls forces b. covalent bonds c. hydrogen bonds d. ionic bonds e. hydrophobic interactions - b. covalent bonds A transmembrane protein has the following properties: it has two binding sites, one for solute A and one for solute B. The protein can undergo a conformational change to switch between two states: either both binding sites are exposed exclusively on one side of the membrane, or both are exposed exclusively on the ot...

What is the working definition of an animal? - Animals are multicellular eukaryotes that are heterotrophic and undergo a blastula stage Two problems associated with morphological classification? - 1. Convergent evolution 2. Minor mutations Why was the organism found in the 90s labelled as a bivalve mollusc? - Because it was consuming bivalve eggs and had traces of their DNA in its gut. What are some problems with molecular sequencing? - 1. Differences in mitochondrial and nuclear DNA ...

BIOL2200 Exam Review | 100% Correct Answers | Verified | Latest 2024 Version Question 1. What is modern cell biology? - An integrated discipline that includes cell culture, microscopy, molecular biology, genetics, and biochemistry. Question 2. What is gene ontology? - A major bioinformatics initiative to unify the representation of gene and gene product (i.e. proteins and RNA) attributes. The project includes development of a controlled vocabulary of a protein's attributes. Question 3. W...

Biomolecular Structure and Function Module This module provides comprehensive, detailed notes covering all aspects of biomolecular structure and function. Topics include the structure and properties of proteins, nucleic acids, lipids, and carbohydrates, as well as their roles in cellular processes. The notes are designed for easy reference and are ideal for exam preparation, ensuring a thorough understanding of key concepts and mechanisms in biomolecular science.

What is the DNA -> RNA process? - RNA polymerase I creates a transcript. This is primary RNA with 5' cap and 3' with poly(a) site. Maturation of RNA includes cleaving at the poly(a) site and RNA splicing of introns to leave matureRNA. What is the mRNA to protein process? - Codons run through ribosome in 3 base pairs. A corresponding tRNA recognises 3 base pair and brings with it conjugate bases and an AA. This adds the relevant AA for every 3 base pair, creating a polypeptide. What is...
