Question
Chapter 19.4, Problem 3AYLO
Summary Introduction
To discuss:
The mechanism that causes cells of the SA node to depolarize rhythmically; a graph of the time course and voltages of the pacemaker potentials; how often it repeats in a normal resting rate; and the role of ion channels and specific ion inflows and outflows in creating the nodal rhythm.
Introduction:
The sinoatrial node (SA) is termed as the pacemaker of the heart because it initiates the heartbeat. It is the prime nodal center of the heartbeatthat enables the trigger-firing actions. Such firing mechanism is done by the specialized cells in the SA node and its membrane potential.

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.
