what is chromosome and its function

Special Types. Chromosomes are located within the nucleus of our cells.They are paired … This unique structure of chromosome keeps DNA tightly packed with histone proteins to fit inside the cell and it also helps in giving more stability to it. They are made of one DNA molecule and protein. In plant and animal cells, it is found within the nucleus. A chromosome is a long, stringy aggregate of genes that carries heredity information and is formed from condensed chromatin.Chromatin is composed of DNA and proteins that are tightly packed together to form chromatin fibers. Karyotypes are pictures of chromosomes. There are two basic types based on function as. Chromosomes. Each species has its own characteristic number of chromosomes. They contain all hereditary information to determine a person's traits, ranging from hair color to height. In most organisms, one chromosome is inherited from the mother and the other is inherited from the father; to ensure that offspring carry traits from both parents. Scientists have given this name chromosomes as they are stained using specific dyes, chroma means colour and soma means body. Chromosomes are filamentous bodies which are typically present in the nucleus and become visible during cell division. Meaning of Chromosomes: Chromosomes are the most important constituents of the nucleus and were first observed by Holfmeister (1848) in pollen mother cell of Tradescantia and called it nuclear filaments. The chromosomes are classified into different types based on shape and position of the centromere. The short arm of the chromosome is labeled the “p arm.” The long arm of the chromosome is labeled the “q arm.” The location of the centromere on each chromosome gives the chromosome its characteristic shape, and can … Like many species of animals and plants, humans are diploid (2n), meaning that most of their chromosomes come in matched sets known as homologous pairs. Functions 6. According to the position of centromere, Types of chromosomes based on function. For starters, notice that there are two copies of each chromosome. Chromosome cytoplasm and plasmid and its function with detail Chromosome Structure and Function A chromosome is a structure that almost looks like thread. Functions of chromosomes: DNA present on the chromosome not only carries most of the genetic information but also controls the hereditary transfer. Humans have 23 pairs of chromosomes. This comes in … They prevent one chromosome from binding to another (DNA is sticky). They also don't have any genetic information. Telomeres function to protect the ends of chromosomes. Chromosomes are essential for the process of cell division, replication, division, and creation of daughter cells. Condensed chromatin fibers form chromosomes. Halocentric chromosome: In these chromosomes, the entire length of acts as centromere. Autosome; Sex chromosomes. Humans, for instance, have 46 chromosomes in a typical body cell, while dogs have 78. It's crucial that certain cells, like reproductive cells, have the correct number of chromosomes in order to function properly. Properties of Chromosomes.
