Textbook Question
Chapter 13, Problem 13.2PS
True or False. Identify each of the following statements as true (T) or false (F). Provide a brief justification for your answer.
(a) The minus end of microtubules and microfilaments is so named because subunits are lost and never added there.
(b) The energy required for tubulin and actin
(c) Microtubules, microfilaments, and intermediate filaments all exist in a typical eukaryotic cell in dynamic equilibrium with a pool of subunit proteins.
(d) Latrunculin A treatment, which blocks actin polymerization, would block intracellular movements of Listeria.
(e) An algal cell contains neither tubulin nor actin.
(f) All of the protein subunits of intermediate filaments are encoded by genes in the same gene family.
(g) All microtubules within animal cells have their minus ends anchored at the centrosome.
(h) As long as the actin monomer concentration is above the overall critical concentration, actin monomers to which CapZ are attached will continue to elongate.

- What is this?arrow_forwardMolecular Biology A-C components of the question are corresponding to attached image labeled 1. D component of the question is corresponding to attached image labeled 2. For a eukaryotic mRNA, the sequences is as follows where AUGrepresents the start codon, the yellow is the Kozak sequence and (XXX) just represents any codonfor an amino acid (no stop codons here). G-cap and polyA tail are not shown A. How long is the peptide produced?B. What is the function (a sentence) of the UAA highlighted in blue?C. If the sequence highlighted in blue were changed from UAA to UAG, how would that affecttranslation? D. (1) The sequence highlighted in yellow above is moved to a new position indicated below. Howwould that affect translation? (2) How long would be the protein produced from this new mRNA?

- Molecular Biology You discover a disease causing mutation (indicated by the arrow) that alters splicing of its mRNA. This mutation (a base substitution in the splicing sequence) eliminates a 3’ splice site resulting in the inclusion of the second intron (I2) in the final mRNA. We are going to pretend that this intron is short having only 15 nucleotides (most introns are much longer so this is just to make things simple) with the following sequence shown below in bold. The ( ) indicate the reading frames in the exons; the included intron 2 sequences are in bold. A. Would you expected this change to be harmful? ExplainB. If you were to do gene therapy to fix this problem, briefly explain what type of gene therapy youwould use to correct this. Please help. Thank youarrow_forwardMolecular Biology Question Please help.
