biochemistry WGU unit 4: DNA and RNA

biochemistry WGU unit 4: DNA and RNA 1. Which nucleotides base-pair together form DNA?: Adenine to thyamine 2. gene expression: process by which a gene produces its product and the product carries out its function 3. DNA: deoxyribonucleic acid Stored in the nucleus DNA does not leave nucleus It must be copied into a new molecule. This molecule is called mRNA or messanger RNA The process of making it is called transcription mRNA gets picked up by ribosomes (machines used to make proteins) 4. Nucleotide: building blocks of nucleic acid. Composed of three parts (sugar, nitrogen, and phosphate). 5. Antiparellel: one strand goes 3' to 5' the other goes 5' to 3' 6. complementary: Each strand of a DNA double helix is the predictable counter- part of the other. A-T or U C to G 7. Which nucleotides/bases are used in DNA?: Adenine, guanine, and cytosine and thymine Adenine to thymine guanine to cytosine 8. Which nucleotides/bases are used in RNA?: Adenine, guanine, and cytosine and uracil Adenine to uracil Guanine to cytosine 9. Which nucleotides base-pair together form RNA?: Adenine to Uracil 10. Template DNA: The pattern for the sequence of nucleotides Changing the letters of a coding strand to make a new sequence This is used to make mRNA coding strand 5' ATA CGA 3' template strand 3' TAT GCT 5' 11. Coding DNA: sequences of a gene's DNA that are coded to produce a specific protein and are transcribed and translated during protein synthesis
