Practice Pg. 45 #1,3,4,10 Pg. 48 #1,2,3,7 Define the term DNA in your own Words and explain its function What is a chromosome? Describe its function What is an allele? Describe its function If a Chromosome is compared to a book, what would the words in the book be compared to? Explain your answer Describe a type of cell division that occurs during the asexual reproduction of a unicellular organism What type of cell division is required for sexual reproduction? How does it differ from the cell division during asexual reproduction. Describe the type of cell division that occurs in the body cells of multicellular organisms If the amount of DNA in a gamete of an organism is n, is the amount of DNA in the body cells of that organism equal to ½n, n, or 2n? Explain
