what is chromosome and its function

They prevent one chromosome from binding to another (DNA is sticky). 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. Chromosome cytoplasm and plasmid and its function with detail Chromosomes. Telomeres function to protect the ends of chromosomes. Humans, for instance, have 46 chromosomes in a typical body cell, while dogs have 78. Humans have 23 pairs of chromosomes. In plant and animal cells, it is found within the nucleus. They contain all hereditary information to determine a person's traits, ranging from hair color to height. Special Types. Autosome; Sex chromosomes. Karyotypes are pictures of chromosomes. Chromosomes are essential for the process of cell division, replication, division, and creation of daughter cells. They are made of one DNA molecule and protein. Each species has its own characteristic number of chromosomes. Chromosomes are located within the nucleus of our cells.They are paired … Condensed chromatin fibers form chromosomes. Functions of chromosomes: DNA present on the chromosome not only carries most of the genetic information but also controls the hereditary transfer. Halocentric chromosome: In these chromosomes, the entire length of acts as centromere. It's crucial that certain cells, like reproductive cells, have the correct number of chromosomes in order to function properly. For starters, notice that there are two copies of each chromosome. According to the position of centromere, Types of chromosomes based on function. This comes in … Properties of Chromosomes. 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. A karyotype, like this karyotype of a human, can teach us several things about chromosomes. 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 … There are two basic types based on function as. 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. 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. 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. Chromosome Structure and Function A chromosome is a structure that almost looks like thread. The chromosomes are classified into different types based on shape and position of the centromere.
