Vessels draining the myocardium of the heart, open primarily ,into which chamber?

Kitty [74]

Answer:

The vessels draining Myocardium of the heart join to form Coronary Sinus that ultimately opens into THE RIGHT ATRIUM.

Explanation:

CORONARY CIRCULATION:

The heart muscles are called as Myocardium. Circulation of myocardium is known as Coronary Circulation. The heart needs to work continuously and requires an uninterrupted supply of blood.

Coronary Arteries supply oxygen rich blood to the myocardium and Coronary Veins remove deoxygenated blood from heart muscles and join to form Coronary Sinus that ultimately drains into the Right Atrium of heart. Some veins from the myocardium also drains directly into the right atrium.

what is the order of three genes (x, y, and z) that are located on the same chromosome, based on the following information? gene

Mekhanik [1.2K]

The recombination frequency between genes is useful to determine the distance between genes and their order in the chromosome. The correct order of genes in this chromosome is X-Z-Y.

<h3>What is the recombination frequency?</h3>

Recombination frequency refers to the probability of crossing-over events occurrence between two genes. There farther genes are from each other, the greater recombination frequency there will be.

Recombination frequencies are also used to determine the distance between genes, and if they are linked or not.

So, if we know the recombination frequencies, we can calculate the distances between the genes and figure the genes' order out.

The map unit is the distance between the pair of genes for which one of the 100 meiotic products results in a recombinant one.

1% of recombination frequency, RF = 1 Map Unit, MU = 1 centiMorgan, cM

Now let us analyze the data

Three genes ⇒ X, Y, Z.
Distance between X-Y = 17% = 17 MU
Distance between Y-Z = 9% = 9 MU
Distance between X-Z = 8% = 8 MU

When the RF is given, we already have the distance between genes.

Now, to put these genes in order, we need to look for the most distant genes. These are probably the ones placed at the extremes of the chromosomal fragment.

In this case, the most distant genes are X-Y. So,

---------X-----------------Y---------

17 MU

Then, we need to place the remaining genes, which are probably between the two extremes genes. To be sure of this position, the addition of these middle genes must equal the distance between the extreme genes.

In our example, we only have one remaining gene Z.

The distance from X to Z = 8 MU
The distance from Y to Z = 9 MU
9 MU + 8 MU = 17 MU which is the distance between X and Y (extreme genes)

-----------X-------------Z----------------------Y---------

║----8MU---║------- 9 MU -----║

║-------------17 MU ---------------║

So, according to this reasoning, the correct order of genes in this chromosome is X-Z-Y.
