The delay between the atrial and ventricular contractions is caused by the atrioventricular node (AV node). The AV node is a small cluster of cells located between the atria and ventricles.
It acts as a gatekeeper, slowing down the electrical signal from the atria so that the ventricles have time to fill with blood before they contract.
There are two main reasons for the delay at the AV node:
The AV node cells have a high threshold for depolarization. This means that they need to be depolarized to a higher level than the cells in the atria before they will fire an action potential.
The AV node cells have a long refractory period. This means that they cannot be re-excited for a period of time after they have fired an action potential.
The combination of these two factors creates a delay of about 0.12 seconds between the atrial and ventricular contractions. This delay is essential for proper heart function, as it allows the ventricles to fill with blood before they contract.

A DNA is the molecule consisting of 2 chains that coil around f each other. Forma a double helix carrying the genetic material the nucleotide is made of nitrogen consisting of cytosine, guanine, adenine, and ethylamine. The biological information is stored in these stands.
The base complementarity of DNA are A = T, G = C
- The single stand consists of nucleotides that are arranged into TGA ATA CCT on the basis of the present complementary strands of DNA.
Learn more about the contains the following nine nucleotides.
Answer;
TGA ATA CCT
Explanation;
- DNA is a nucleic acid that stores all the genetic information of an organism.
- DNA is a double stranded molecule and contains the nucleotide bases, Adenine, Guanine, Thymine, and Cytosine.
- The DNA strand and its complementary strand are held together by hydrogen bonds between the base pairs on both stands. Guanine base on one strand is bonded to Cytosine base on the opposite strand. Adenine bonds or pairs with Thymine base on opposite strand.
