It creates RNA copies of the genes for the cells to use and results in the formation of mRNA, tRNA, etc. RNA Synthesis: RNA synthesis or transcription is a process by which the gene codons are copied into RNA polymerase. Genes are the basic unit in the study of genetics. Genes and Alleles are the same thing. The entire DNA in cells can be found in individual pieces that are called chromosomes. Chromosomes are the structures that carry genes from one cell to another through cell division; thus, they must be replicated via mitosis. Genetic is the study of the biological inheritance of traits and variation. Where does a gene come into this. Almost every human’s genome, chromosomes and genes are organised in the same way. Genes are sections of DNA, for example, your DNA determines your hair colour etc, you have a gene for hair colour, eye colour etc, [all parts of the DNA.] 2/1 9/2 01 7 Differen ce B etwee n DNA a nd Chromoso me … Genes and chromosomes are understood as similar structures by most of the people. It’s the DNA code, the words on the page, that are slightly different. If the DNA code is a set of instructions that’s carefully organised into paragraphs (genes) and chapters (chromosomes), then the entire manual from start to finish would be the genome. About 200 to 200 number of different genes are present in autosomes, and the chromosome 1 in humans which is known to be the largest contains approximately 2800 genes; in contrast, the X sex chromosome consists of more than 300 types of genes, and y sex chromosome consists of merely a few examples of genes because it is relatively small in size.

Let us see how chromosomes are formed from double stranded DNA. Key differences between Gene and Genome Genes are inheritance units composed of DNA and occupy a fixed position on the chromosomes, while the genome surrounds the set of genes contained in a chromosome. When these segments are coiled in a form that can be easily duplicated, they are known as chromosomes. On the other hand, a Gene is just a portion of DNA molecule which is responsible for carrying a message resulting in the synthetic of proteins from amino acids. When "mapping" all genes on all human chromosomes was first seriously conceived, it was called the Human Genome Project - a combination of gene and chromosome. The basic structure of a gene in a DNA strand could be explained according to the description of the two scientists James Watson and Francis Crick in 1953, for which they won the Nobel Prize, as well.
