Faahfaahinta casharka

Natiijada casharka

Waxaan sharxi karaa farqiga u dhexeeya DNA-da, koromosoomyada, hiddo-wadayaasha iyo genome-ka.

Hordhac

Waxaad horey uga soo qaadatay cutubka 'Heredity and DNA' waxa ku saabsan sida astaamaha loogu gudbiyo jiilka. Casharkan, waxaad baran doontaa ereyada muhiimka ah sida **DNA, chromosomes, genes iyo genome** si aad u fahamto sida DNA ugu xidhan tahay gudaha **noole (organism)**.

Muuji qoraalka
All organisms have a genome, and there are similarities and differences between the genomes of different organisms. The genome is made of DNA, wound up into tightly-packed structures called chromosomes. Human body cells have 23 pairs of chromosomes, stored in the nucleus; bacteria have one that is stored in the cytoplasm. Sections of the DNA in chromosomes are called genes, which store instructions for inherited features and life processes. Other sections are non-coding DNA, which contains instructions that controls when the information in genes is used.
