endoplasmic reticulum - Ans:✔✔-- protein management


golgi apparatus - Ans:✔✔-- package


ribosomes - Ans:✔✔-translate RNA to proteins


lysosomes - Ans:✔✔-contain degradative enzymes


cytoskeleton - Ans:✔✔-- provide structure, "madways" and polarity to cell


function of DNA in controlling cell function - Ans:✔✔--stable DNA molecule (contains the information

needed for control of the cell structure and function)


- every cell in the body contains the same genetic information


(each cell type uses only a portion depending on its structure and function)


- four bases making up the alphabet of the genetic code ( adenine, cytosine, guanine and thymine (in

RNA, uracil))


protein formation - Ans:✔✔-- proteins formed from DNA translation have a specific shape


- amino acid sequence determines shape


- 3-4 levels of protein structure


- form will influence function (improperly formed proteins -> alteration in function)
