Map the following onto this image. What parts of the protein making process are affected when genes are regulated through….(maybe connect with arrows?) • epigene?c modifica?ons • transcrip?on factors DNA • post transcrip?onal modifica?on mRNA (RNA processing, RNA splicing) Ribosome Ribosome • microRNA Polypeptide Polypeptide • post transla?onal modifica?on
Use terms in parentheses as well as the following …..gametes, zygote, replica8on Sperm are_____________ (single celled/mul?celled) and _______________(diploid/ haploid). Eggs are_____________ (single celled/mul?celled) and _______________(diploid/haploid). When sperm fer?lizes an egg a __________________ is formed which is ____________(haploid/diploid). This goes through______________ (mitosis/meiosis) over and over again to create a mul?cellular body. During this process the DNA in the cells must go through______________. Once an adult mul?cellular organism exists it is ____________ (haploid/diploid). In humans each cell will have _________________ chromosomes. At this point germ cells in the mul?cellular body must go through_____________(mitosis/meiosis) to make __________. These are _____________(haploid/diploid) and have ___________ chromosomes in humans.
