Faahfaahinta casharka

Natiijada casharka

Waxaan sharxi karaa dhismaha DNA-da oo waxaan qiimeyn karaa moodellada loogu talagalay.

Hordhac

Soo dhawoow casharkan oo ka mid ah cutubka 'Heredity and DNA'. Haddii aad hore uga warqabtid waxa unugyada kugu jira iyo sida ay u sameeyaan, waxaad diyaar u tahay inaad sahamiso molecule-ka weyn ee DNA. Casharkani wuxuu ku saabsan yahay qaabka gaarka ah ee DNA iyo sida loogu qaabeeyo iyo loo qiimeeyo qaababkaas, adigoo hore u yaqaan fikradaha aasaasiga ah ee unugyada iyo hidaha.

Muuji qoraalka

Genetic material is made of DNA. DNA is a long chemical molecule, made of two chains of smaller chemical units joined together. All of the DNA in a cell is called the genome. The chains are spiralled around one another in a double helix, with links across the middle. Scientific models of DNA can be evaluated for their strengths and weaknesses.
