Why is having an extra chromosome 21 tolerable to the point that someone with this condition can survive to maturity?
Vilka [71]
I think that having an extra chromosome 21 is tolerable to the point that someone with this condition can survive to maturity because it does not replicate.

There should only be a pair of chromosome 21. In the event that there are 3 chromosome 21, the person that has this extra chromosome has Down syndrome. Changes in the number and structure of this chromosome may result to delayed development, intellectual disability, but not immediate death.

yanalaym [24]

Answer:

1. chromosome: tight coils of DNA

2. Eukaryote: a cell that has a membrane-bound nucleus

3. Gene: a specific sequence of DNA nucleotides that carry hereditary traits

4. Prokaryote: a cell whose nucleus is not bound by a membrane

5. Trait: genetic characteristic of an individual

Explanation:

Chromosomes are the thread-like structures that appear during cell division. Each chromosome is made up of DNA tightly coiled with its packing proteins.  

A cell is defined as eukaryote or prokaryote on the basis of the presence of a membrane-bound nucleus. The cells that lack the membrane-bound nucleus and other membrane-bound organelles are called prokaryotic cells. Example: bacteria.

The cells that have a membrane bound nucleus in which DNA is present are called eukaryotic cells. Example: Plant cells.

A stretch of DNA that code for a particular protein and thereby regulate specific genetic trait is called a gene. Genes are present on chromosomes and are carried from one generation to next to maintain the genetic traits.

The features of living beings regulated by the gene are called trait. Example: skin color, eye color, etc.
