chapter 7

• DNA - molecule of nucleic acid, made up of monomers called nucleotides
• DNA stores the information that the cell needs to produce proteins.
• Each nucleotide has: 1 phosphate group, 1 deoxyribose sugar, 1 nitrogenous base (ATCG)
• Hydrogen bonds form between nitrogenous bases to connect DNA strands: Adenine and Thymine, Cytosine and Guanine
• Phosphate group is attached to 5-prime dexyribose.
• OH group is attached to 3-prime deoxyribose.
• DNA is antiparallel.
• Gene - small region of a chromosome
• Transcription - RNA synthesis, uses DNA as template to create RNA, occurs in nucleus
• Messenger RNA - carries message on how to make proteins from DNA for transcription
• Ribosomal RNA - make up the ribosome, site of protein synthesis for translation
• Transfer RNA - transfers amino acids to ribsomes for translation
