DNA is found in the nucleus - DNA stands for DeoxyriboNucleic Acid - The DNA molecule comes in the form of a twisted ladder and scientists call its shape a double helix - A always pairs with T, and C always pairs with G - The DNA strand is made of letters, the letters make words, the words make sentences. These sentences are called genes. Genes tell other molecules to make proteins.Proteins enable a cell to perform special functions, such as working with other groups of cells to make hearing possible - Sugar and Phosphate make up the sides of a DNA molecule - G stands for Guanine, A stands for Adenine, T stands for Thymine, C stands for Cytosine
Genes are made of DNA. They are instruction manuals for our bodies. - Hemoglobin is responsible for our red blood cells to carry oxygen. - If our hemoglobin gene is normal, the hemoblobin protein will work fine. But if the instructions in the gene are changed, or mutated, changes in the hemoglobin could result in the disorder sickle cell anemia. DNA OR GENES are responsible for our eye color
If you pulled the DNA from one of your cells it would stretch 3 meters. The DNA is packaged into compact units called chromosomes - Different organisms have a different number of chromosomes inside each cell - Each human has 46 chromosomes. You received 23 of your chromosomes from your mom and 23 from your dad. Males have "Y" chromosomes and "X" chromosomes. Females have "X" chromosomes. - a mosquito has 3 chromosomes. an onion has 8 chromosomes. a carp has 52 chromosomes.
DNA, the molecule that holds genetic material, makes an exact copy of itself whenever it divides. Enzymes moving up the rungs and breaking them is the first step of DNA Replication. DNA unzips on the rungs of the ladder. Ademine always goes with Thymine and Cystosine always goes with Guanine.
