Document Summary

Somatic cells: most cells in body (except sex cells) Cytoplasm : complex mix of membranes, molecules, and tiny structure called organelles. Paires rod shaped structures in cell nucleus containing genes that transmit traits from generation ( the x shape is a dna) Dna - deoxyribonucleic acid: nucleic acid used to store generation information that codes for the synthesis of proteins. Four bases: adenine and thymine ( t with a), guanine (g with c ) cytosine. Nasa 2011: reported that meteoroids founded earth, contain nucleobases such as adenine and guanine maybe have been formed in outer space. Dictate synthesis of proteins that perform a wide variety of functions in body. Work with structures in cell (ribosomes) that are critical for manufacture of proteins. Transport amino acids to ribosomes for the creating of proteins. Linear sequences of amino acids; building blocks of cell. Each protein has specific function determined by blueprint stored in dna.
