The only thing you can say is that organs and tissues are made of many cells, so they tend to be bigger than cells. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Chromosomes are structures that look like thread, which live in the nucleus (center) of cells. The list of organisms by chromosome count describes ploidy or numbers of . Also, all its chromosomes are approximately equal in size. From smallest to largest, the order is nitrogenous base, nucleotide, codon, gene, chromosome, nucleus, and cell. Number 4.

Overview and Key Difference Explain with suitable example. Chromosomes are visible only during the metaphase of cell division. Twenty-two of these pairs, called autosomes, look the same in both males and females. i) Low molecular weight proteins: histones or basic proteins; ii) High molecular weight proteins or non-histones or acidic protein. The length of chromosomes varies from 1 (some fungi) to 30 (Trillium). Its closest relatives are the diploid (2n = 2x = 20). Just like a thread wound around a cardboard tube. Some genes code for RNA, which does other jobs. The X and Y chromosomes are not autosomes. [4] The preparation and study of karyotypes is part of cytogenetics. 3 Gene - a segment of DNA that provides the genetic code for a particular trait or characteristic via the assembly of a protein. A genetic mutation is a gene that didnt copy correctly during cell division, and it has a different sequence or shape from other genes in the body. The cell is the basic biological unit of the organism, so an organism is made up of one or more cells. There are 22 pairs of chromosomes, called autosomes, which match up . 2. Now, judging by the given options, only the second alternative has the Liver as the largest in terms of size and structure. Chromosomes are arranged in pairs according to their size and structure (largest = chromosome pair 1, smallest = 22) The 23rd pair are the sex chromosomes.
