What are chromosomes?
The human chromosome is the basic building block of life and is one of the most important components of the cell to be transmitted from generation to generation. It is essentially an organized structure of DNA that exists within the nucleus of all human cells and comprises a single chain of DNA that is coiled and super coiled to form dense thread like pieces.
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
The term chromosome comes from the Greek words for colour (chroma) and body (soma). Scientists gave this name to chromosomes because they are cell structures, or bodies, that are strongly stained by some colourful dyes used in research.
What do chromosomes do?
The unique structure of chromosomes keeps DNA tightly wrapped around spool-like proteins, called histones. Without such packaging, DNA molecules would be too long to fit inside cells. For example, if all of the DNA molecules in a single human cell were unwound from their histones and placed end-to-end, they would stretch 6 feet.
For an organism to grow and function properly, cells must constantly divide to produce new cells to replace old, worn-out cells. During cell division, it is essential that DNA remains intact and evenly distributed among cells. Chromosomes are a key part of the process that ensures DNA is accurately copied and distributed in the vast majority of cell divisions. Still, mistakes do occur on rare occasions.
Changes in the number or structure of chromosomes in new cells may lead to serious problems. For example, in humans, one type of leukemia and some other cancers are caused by defective chromosomes made up of joined pieces of broken chromosomes.
It is also crucial that reproductive cells, such as eggs and sperm, contain the right number of chromosomes and that those chromosomes have the correct structure. If not, the resulting offspring may fail to develop properly. For example, people with Down syndrome have three copies of chromosome 21, instead of the two copies found in other people.
Chromosomes are genetic in nature. For example, chromosomes make the bones, but how we use those bones is up to us. The extra chromosome 21 creates Down’s syndrome, which causes all the facial bones to go into flexion, so they look a certain way, that doesn’t mean we can’t reverse it, because it has been reversed, but a person can’t do it naturally.
When identifying and attempting to change a genetic influence that has a filtering mechanism connected to it in the nervous system then these changes can take ages to manifest.
Changing something at the genetic level, particularly the chromosomes, takes a while to filter through all the process it governs before it gets to an observable response. It can take years to get through. Can chromosomes be reactive? Chromosomes have inter-relationships but don’t aggravate each other. The reactivity is in the functions they create the way they react to each other.
Example: Down’s syndrome is an observable effect of an extra chromosome. The various functions it produces will be reactive to other functions. Disease patterns will be reflected in some part of the genetic system; they are encouraged weaknesses. These inherent weaknesses, aren’t reactive to each other, one is just dominate or not.
As per Hahnemann’s observation of suppression, a stronger disease suppresses a weaker disease. That’s a genetic phenomenon. One gene is stronger than another.
