Document Summary
Somatic cells: most cells in body (except sex cells) Cytoplasm: complex mix of membranes, molecules, and tiny structures called organelles. Paired rod shaped structures in cell nucleus containing genes that transmit traits from generation to generation. Molecules strung together (unwind, results in strings of dna) Deoxyribonucleic acid: nucleic acid used to store genetic information that codes for the synthesis of proteins. Four bases: adenine (a), guanine (g), cytosine (c), thymine (t) (a&t go together, c&g go together) Determines how genes are expressed based on which protein is created (which code in dna) Linear sequences of amino acids; building blocks of cells. Each protein has specific function determined by blueprint stored in dna. Catalysis of all biochemical reactions is done by enzymes, which contain protein; and many more. Synthesis of single strand of rna (mrna - messengerrna) at unwound section of. Dna with one strand of dna acting as template. Result: genetic information encoded in dna is transferred to rna.
