A sugar (deoxyribose), a phosphate which links the sugars together, and then one of the four bases. The sections of dna that do actually code from proteins are called exons. If you enjoy steam activities for kids, odds are good youโre going to dive into a lesson on dna. Web study with quizlet and memorize flashcards containing terms like full name of dna, what is a gene?, where in the cell are chromosomes located? The pyrimidines are thymine and cytosine.
The sides of the ladder are made of alternating sugar and phosphate molecules. Web you colored them in the double helix. Recall that the nucleus is a small spherical, dense body in a cell. The two sides of the dna ladder are held together loosely by hydrogen bonds.
Each nucleotide contains a phosphate, sugar (deoxyribose in dna), and one of four nitrogen bases (adenine, guanine, cytosine, thymine). The rungs of the ladder are pairs of 4 types of nitrogen bases. Color the images according to your instructions.
The sides of the ladder are made of alternating sugar and phosphate molecules. These regions of dna that do not code for proteins are called introns, or sometimes junk dna. Edexcel (igcse) igcse science 3: Chromosomes, found in the nucleus, are microscopic, threadlike strands composed of the chemical dna (short for deoxyribonucleic acid). How does it do this?
