SOLUTIONS GRADED A+
◉ Cell cycle. Answer: Life of a cell from the time it's first formed
during division of a parent cell until its own division into 2 daughter
cells
◉ Genome. Answer: Complete instructions for making an organism,
consisting of all the genetic material in that organism's chromosomes
◉ Chromosomes. Answer: Threadlike structures made of DNA
molecules that contain the genes
◉ Chromatin. Answer: Entire complex of DNA and proteins that are the
building material for chromosomes

coiled in chromatin
◉ Somatic cells. Answer: Cells in the body other than reproductive cells
, ◉ Gametes. Answer: Reproductive cells; have half of the chromosomes

chromosomal DNA, where the chromatid is attached most closely to its
sister chromatid
