Biology
1 answer:
seropon [69]3 years ago
5 0
<h2>Answer:</h2>

It is due to <u>secretion process</u> that John's blood contains high amount of toxin.

<h2>Explanation:</h2>

If the secretion is not proper, it leads to high amount of toxins in blood.

The organs system which is involved in removal of waste product from the body is called as excretory system. Kidney is the major organ of excretory system. The nephron is considered as the structural as well as functional unit of kidney.  

Every nephron starts with a filtration part that channels the blood entering the kidney. This filtrate at that point streams along the length of the nephrons, which is a cylindrical structure lined by a solitary layer of specific cells and encompassed by vessels.

Such type of arrangement is involved in sending back the required substance into the body by process called reabsorption, and sending the wastes out the body through process called secretion.

Which of the following correctly explains where DNA replication will begin on the strand oriented 5'→3', reading from left to
padilas [110]

The process of DNA replication is ALWAYS started immediately to the left of the RNA because DNA polymerase is an enzyme that needs RNA primer. It is required the presence of a primase for this process.

<h3>DNA replication and primase</h3>

DNA replication is always initiated by a specific RNA polymerase referred to as primase.

Primase is an RNA polymerase that generates a short  RNA oligonucleotide known as primer, which is complementary to the DNA strand.

Subsequently, DNA replication is started immediately to the left of this RNA primer where DNA polymerase adds nucleotides to the growing DNA strand.

In conclusion, the correct (and missing) statement here is 'the process of DNA replication is ALWAYS started immediately to the left of the RNA because DNA polymerase is an enzyme that needs RNA primer'.
