Dna uppgifter

DNA (forkortning av engelskans deoxyribonucleic acid) eller deoxiribo nukleinsyra ar det kemiska amne som bar den genetiska informationen (aven kallad arvsmassa eller genom), i samtliga av varldens kanda organismer (med undantag av RNA-virus). DNA- molekylen finns i identiska kopior i varje cell i en organism. 1 forklara dna for barn 2 DNA structure and function. DNA is the information molecule. It stores instructions for making other large molecules, called proteins. These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes. 3 var finns dna 4 DNA bar pa den genetiska informationen. Avery, MacLeod och McCartys experiment. Griffiths transformationsexperiment med R- och S-stam av pneumokocker: Alltsa; var och en for sig ar den levande R-stammen och den avdodade S-stammen ofarliga – men tillsammans ar de dodliga! Den ofarliga S-stammen transformeras till dodlig R-stam. 5 What does DNA do? What is DNA made of? Who discovered the structure of DNA? Can you edit DNA? What’s the difference between DNA and RNA? DNA, abbreviation of deoxyribonucleic acid, organic chemical of complex molecular structure that is found in all prokaryotic and eukaryotic cells and in many viruses. 6 Each DNA sequence that contains instructions to make a protein is known as a gene. The size of a gene may vary greatly, ranging from about 1, bases to 1 million bases in humans. Genes only make up about 1 percent of the DNA sequence. DNA sequences outside this 1 percent are involved in regulating when, how and how much of a protein is made. 7 hur ar dna uppbyggt 8 DNA ar det kemiska amne som. 9 Informationen lagras inuti celler i form av DNA och anvands for att tillverka proteiner (och RNA-molekyler). 10
