what is the importance of the chromosomes?

Chromosomes are very important because they contain vast majority of genetic information of organism. The organism's DNA is contained within the chromosome as a long series of nucleotides thar are organised into genes. And helps to inherit the characters of parents to their offsprings.

Chromosomes also contain chemical substances that govern the function of genes. The human body consists of millions of cells; each cell (liver, intestinal etc) contains 23 pairs of chromosomes except for germ cells (egg and sperm) and red blood cells. Thus a total of 46 chromosomes are present in human cells.

There are four main types of chromosomes: metacentric, submetacentric, acrocentric, and telocentric. Chromosomes are found within the nucleus of most living cells and consist of DNA that is tightly wound into thread-like structures.

The chromosomes serve as the structure that holds the DNA. The DNA acts as a complete set of instructions that tells our bodies how to develop. Storing more data than any computer, each chromosome contains all the information needed to give you a base for your physical (and emotional) characteristics.

Chromosomes come in pairs. Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes). Half come from the mother; the other half come from the father. Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born.

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).

DNA is coiled around proteins called histones, which provide the structural support. Chromosomes help ensure that DNA is replicated and distributed appropriately during cell division. Each chromosome has a centromere, which divides the chromosome into two sections – the p (short) arm and the q (long) arm.

Chromosomes are bundles of tightly coiled DNA located within the nucleus of almost every cell in our body. Humans have 23 pairs of chromosomes. Illustration showing how DNA is packaged into a chromosome. ... The chromatin loops are then wrapped around each other to make a full chromosome.

Centrosome is an organelle in the cell which is responsible in the division of cells. While chromosomes are highly condensed coiled chromatin fibres that is present inside the nucleus.

Genes are made of DNA. ... Chromosomes are packages of compact DNA. How many chromosomes does a human cell hold?

chromosomes are the strands of DNA that carry genes and gametes are the cells that are formed after meiosis and specifically carry the haploid number of chromosomes.

Functions of chromosomes: DNA present on the chromosome not only carries most of the genetic information but also controls the hereditary transfer. Chromosomes are essential for the process of cell division, replication, division, and creation of daughter cells.

Chromosome analysis or karyotyping is a test that evaluates the number and structure of a person's chromosomes in order to detect abnormalities. Chromosomes are thread-like structures within each cell nucleus and contain the body's genetic blueprint. Each chromosome contains thousands of genes in specific locations.

The most important function of chromosomes is to carry genes—the functional units of heredity. A gene is usually defined as a segment of DNA that contains the instructions for making a particular protein (or a set of closely related proteins).
541958
Along the segments of our DNA, genes are neatly packaged within structures called chromosomes. Every human cell contains 46 chromosomes, arranged as 23 pairs (called autosomes), with one member of each pair inherited from each parent at the time of conception.

The most important function of the nucleus is to store the cell's genetic information in the form of DNA. DNA holds the instructions for how the cell should work. DNA stands for deoxyribonucleic acid. The molecules of DNA are organized into special structures called chromosomes.

Answer and Explanation: DNA replication is important because without it the new cells that are produced during mitosis or meiosis would eventually die.
