Porth’s Essentials Of Pathophysiology 5th Edition Test Bank 1. Chapter 1 Although the basic structure of the cell plasma membrane is formed by a lipid bilayer, most of the specific membrane functions are carried out by: A) Bound and transmembrane proteins B) Complex, long carbohydrate chains C) Surface antigens and hormone receptors D) A gating system of selective ion channels Ans: A Feedback: The functions of plasma membrane depend on the presence of proteins that are bound in the lipid bilay...

Lesson Plan: Title Transcription Part II: What happens to the initial (premRNA) transcript made by RNA pol II? Objectives  Explain how the transcript generated by RNA polymerase II (the pre-mRNA) is processed to become mature mRNA, using the sequence signals identified in Module 2.  Use the genome browser to analyze the relationships among: 1. pre-mRNA 2. 5’ capping 3. 3’ polyadenylation 4. splicing 5. mRNA Pre-requisites  Modules 1 and 2  Define pre-mRNA as the RNA ...

What modification neutralizes the charges on histones and looses up the interactions between histones and DNA? - Answer- ACETYLATION Two types of post-transcriptional modifications that take place in the mRNA of eukaryotes - Answer- the addition of a CAP at the 5' end of the transcript and the addition of a POLY A sequence at the 3' end of the message Nucleic acid blotting is widely used in recombinant DNA technology. In a Southern blot one generally - Answer- Hybridizes filter-bound DNA...

What is the magnification of an ocular lens on a microscope? - 10X What part of the microscope is the slide going to be placed on? - Stage All humans have how many pairs of chromosomes? - 23 What holds the genetic code for each person? - DNA What is DNA made of? - nucleotides The plasma membrane is made of how many phospholipid layers? - 2 (Bilayer) How is oxygen transported through blood or body? - circulatory system The mRNA strand is what to DNA strand? - Identical except U is where T ...

Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary - ANSWER Primary The primary structure of a protein is the sequence of amino acids held together by peptide bonds. Peptide bonds are formed by dehydration reactions and disrupted by hydrolysis. A mutation in the beta-hemoglobin gene, which results in the replacement of the amino acid glutamate in position 6 with the amino acid valine, leads to the develop...

Based on the data presented in the passage, which statement best describes the HSP110ΔE9 allele? A.Cancer-promoting and dominant to HSP110WT B.Cancer-promoting and recessive to HSP110WT C.Cancer-suppressing and dominant to HSP110WT D.Cancer-suppressing and recessive to HSP110WT - Cross out A and B. LOOK AT THE FIGURE! Tumor volume is DOWN. Table 2 shows that HSP110ΔE9 allele when mixed with HSP110WT there is more apoptotic cells. So it's dominant. SLOW THE HECK DOWN AND READ ...
