Answer:
The correct answer is option B) "a deletion of two nucleotides".
Explanation:
A frameshift mutation is a type of genetic modification caused by the insertion or deletion of one or more nucleotides in a position that results in changing the sequence at which codons are translated in the ribosome. Frameshift mutations have the most serious effect on the polypeptide products since it results in changing completely the sequence of the protein. A deletion of two nucleotides after the AUG start of translation would result in a frameshift mutation, therefore this mutation would have the most serious effect on the polypeptide product.
Answer:
1. Ventricular depolarization −−QRS complex
2. Total time it takes for the ventricular muscle to depolarize and repolarize −−QT interval
3. Atrial depolarization −−P wave
4. Conduction through the atrioventricular (AV) node −−PR segment
5. Ventricular repolarization −−T wave
6. The ventricles are in their depolarized state −−ST segment
7. Conduction through the atrioventricular (AV) bundle −−Q wave
Explanation:
ECG or electrocardiogram is the graphical representation of the heart's rhythm and electrical activity measured by electrical signals. The contraction of the heart shows electrical activity.
There are various deflections shows from baseline and known as specific waves and there are also some flat lines between waves called intervals. This atrial depolarization is called P wave and ventricular repolarization called T wave and the time between ventricular muscles depolarization ( QRS complex) and repolarization is QT interval. Conduction through the atrioventricular (AV) bundle is known as Q wave.
