Functoin of the chromosomes

Answer 1

Chromosome are a structure in a cell's nucleus that contains hereditary material.

Answer 2

it delivers the information needed to the nucleus
A chromosome is an organized structure of DNA and protein that is found in cells. It is a single piece of coiled DNA containing many genes, regulatory elements and other nucleotide sequences. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions.

Answer 3

Chromosomes are small structures that are contained in the cell's nucleus. They each look like a "H" or "X" shape and are made up of genes, which contain DNA (Deoxyribonucleic Acid), the carrier of your genetic info. This genetic info controls each cell, and each cell is unique because of these little wonders called chromosomes. When a cell divides, the DNA sequence is copied for each gene, creating a copy of the entire chromosome for the new cell.

DNA and RNA

RNA is transcribed from DNA by enzymes called RNA polymerases and is generally further processed by other enzymes. Some of these RNA-processing enzymes contain RNA as part of their structures. RNA is also central to the translation of some RNAs into proteins. In this process, a type of RNA called messenger RNA carries information from DNA to structures called ribosomes. These ribosomes are made from proteins and ribosomal RNAs, which come together to form a molecular machine that can read messenger RNAs and translate the information they carry into proteins. It has also been known since the 1990s that several types of RNA regulate which genes are active. re...

Chromosomes are made up of DNA and protein. They are found in the of every cell in the human body (except for red blood cells), and any other animal/plant. In a human they come in "pairs", 23 of them to be exact. 23 chromosomes come from the father and 23 from the mother; each contains the same type of information as it's pair from the other set.

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.
