Why are telomeres a necessary component of linear chromosomes?

Biology

Lerok [7]3 years ago

Answer:

Bacause they protect the chromosomes

Explanation:

A telomere is a repetitive region located at the ends of a chromosome, their function is to act as caps to protect the inner regions when the chromosome is worn down during DNA replication. This worning out happens because a short stretch of DNA is not covered by an Okazaki fragment and therefore is not copied, eventually over multiple rounds of division <em>the telomers will prevent the shortening to reach the important inner part that contains the genetical information.</em>

I hope you find this information useful and interesting! Good luck!

Angioplasty is the most typical treatment for arteriosclerosis. Please select the best answer from the choices provided. T F
Lemur [1.5K]

The right answer is false.

Angioplasty is a technique that can reopen narrowed or obstructed arteries in the heart (coronary arteries) without extensive surgery. First performed in 1977, angioplasty is now as common as coronary artery bypass graft surgery.

The treatment of arteriosclerosis is surgical or endovascular if there is a risk of life, significant functional impairment or major risk involving the life of an organ or limb.


Angioplasty is not the only surgery for this, Several surgical techniques aim at restoring the arterial lumen or irrigating the private territory or at suppressing the arterial aneurysm.

- Endoluminal angioplasty or dilation using a balloon with or without a stent to correct a stenosis or to recanalize a short arterial occlusion.

- The removal by endarterectomy which consists of removing the atheroma plug which obstructs an artery leaving only the weed.

- Bridging, which will "short circuit" the obliterated artery by allowing the passage of blood from the healthy artery upstream to the permeable artery downstream, made with venous, arterial or prosthetic material.


In case of an aneurysm two techniques are available: either bypass surgery in conventional surgery removing the aneurysm - or the stent covered excluding the aneurysm.

In all cases the risks must be compared to the benefits of each technique and correctly exposed beforehand. Each act must be adapted to each case according to the functional stage, the general state of the patient and his physiological age more than legal.
