The telomere is the protective cap of DNA on the tip of chromosomes.
You lose a small amount of these telomeres each time the cell divides. Eventually the telomeres be lost as you age. Short chromosomes because of lack telomeres are one reason aging occurs.
The protective cap of DNA on the tip of chromosomes is called a telomere. Telomeres help maintain the stability of chromosomes and prevent the loss of genetic information during cell division. As cells age, telomeres naturally shorten, eventually leading to cell death or senescence.

What is the layer of tough protective cells that protects the delicate root tip as the root pushes its way through the hard ground?
caps
What is the function of the root cap-?
A root cap is a small cone of cells that protects the growing part of a root as it makes its way through the soil, the root cap is found covering the tip of a root. Right behind the root cap is the part of the root where most of the root's growth occurs.
What is the purpose of heating the onion root tip cells and the acetocarmine stain?
Heating the onion root tip cells softens the cell walls and allows the acetocarmine stain to penetrate the cells. The stain then binds to the DNA in the cells, making the chromosomes visible under a microscope for easier observation and analysis in cell division studies.
What meristem does the root cap originates?
The root cap originates from the calyptrogen, which is a specialized meristematic tissue located at the tip of plant roots. The cells of the calyptrogen continuously divide and differentiate to produce the root cap, which protects the root tip as it grows through the soil.
What is the function of root tip in plant?
The root tip is responsible for absorbing water and nutrients from the soil, allowing the plant to grow and survive. It also helps anchor the plant securely in the ground. Additionally, the root tip contains cells that continuously divide and produce new cells, contributing to root growth and development.
Is the root cap a protective tissue?
Yes, the root cap is a protective tissue located at the tip of a plant root. It helps to protect the delicate meristematic cells behind it as the root pushes through the soil.
The protective layer of cells that covers the actively growing tip of a root?
The protective layer of cells that covers the actively growing tip of a root is called the root cap. Its function is to help guide the root through the soil and protect the delicate cells of the root tip as it pushes through the soil in search of water and nutrients.
What is the name of the string of repetitive DNA at the tip of each chromosome in the body?
The repetitive DNA at the tip of each chromosome is called a telomere. Telomeres protect the chromosome from deterioration or fusion with neighboring chromosomes, and they shorten with each cell division. This shortening is linked to aging and disease.
What is the layer of tough protective cells that protects the delicate root tip as the root pushes its way through the hard ground?
caps
Use of acetocarmine in onion root tip squash?
Acetocarmine is a DNA specific stain like feulgen stain, so the super coiled chromosomes during different stages of mitosis present in the Onion root tip cells can be visualized perfectly by treating with this stain.
What covers the tip of the root?
Root cap
What protects the lower tip of a root?
A root cap
How do you clean a cap gun?
Use a Q-tip.
Whbat is the function of the root cap?
The function of the root cap is to protect and cover the growing tip of the root.
What is the layer of tough protective cells that protects the delicate root tip as the root pushes it's way through the hard ground?
I think you mean the calyptra, or root-cap. However, rather than being a tough layer, it contains liquified cells that lubricate soil patricles.it is called a root cap.
What is the function of the root cap-?
A root cap is a small cone of cells that protects the growing part of a root as it makes its way through the soil, the root cap is found covering the tip of a root. Right behind the root cap is the part of the root where most of the root's growth occurs.
How long does a girls lacrosse have to be?
A field player's crosse must be between 90cm and 110cm (between 35.5" and 43.25") tip-to-tip (including the end cap). A goalie's crosse must be between 90cm and 122cm (between 35.5" and 48") tip-to-tip (including the end cap).
