Chromosomes are made of DNA, and genes are special units of chromosomal DNA. Each chromosome is a very long molecule, so it needs to be wrapped tightly around proteins for efficient packaging. Our genetic information is stored in 23 pairs of chromosomes that vary widely in size and shape.

Idiograms provide a pictorial reference point that is useful for locating the positions of individual genes on chromosomes, as well as for identifying various abnormalities associated with a...
Draw the structure of an ‘average’ human gene. Categorize the human gene catalog into different functional classes. Distinguish between conventional and processed pseudogenes and other types of evolutionary relic. Give specific examples of the repetitive DNA content of the human genome.
As well as knowing in which cells a gene is expressed, it is often useful to locate the position within the cell where the protein coded by the gene is found. For example, key data regarding gene function can be obtained by showing that the protein product is located in mitochondria, in the nucleus, or on the cell surface.
DNA and gene functions. Investigating interactions between DNA sequences, gene products, and environmental factors. Comparing the genomes of humans and other organisms
29 mar 2021 · Chromosomes are made of double-stranded DNA molecules wound about histones and condensed into the familiar X-shape. Under regular functioning, these chromosomes are decondensed in the nucleus and not recognizable. Chromosomes in Interphase are not visible individually.
