The continuity of life is based on heritable information in the form of DNA, and structure and function are correlated at all levels of biological organization. In a short essay (100−150 words), describe how the structure of DNA is correlated with its role as the molecular basis of inheritance.
Chromosomes pass genetic information from one cell to another in cell generation.
(j) Explain the relationship between DNA, genes, and chromosomes during the passing of genetic information.
(k) During the passing of genetic information from one generation to the next via chromosomes, nondisjunction can occur, interrupting the process. Describe the events that take place during nondisjunction.
Background: DNA nucleotides (i.e A, T, G, and C) are naturally found in a paired, or bonded, arrangement
(i.e. the double helix) within the nucleus of every cell. This structure makes the process of replication that
occurs prior to mitosis and meiosis very reliable. The purpose of DNA, though, is not simply to make copies of
itself, but to provide a set of instructions for the synthesis or "construction" of biomolecules, such as proteins.
Why is transcription (i.e. the formation of an RNA copy of a given gene) a necessary step in the
"construction" process highlighted above? What is the cell looking to ultimately do with this RNA
information?

Because cell division plays several important roles in life, it is important that the cycle be regulated.Which of the following are reasons the cell cycle must be regulated? Select all that apply.[ ]To make sure cells only divide when conditions are favorable for growth and development of the organism[ ]To make sure daughter cells end up with the right number of chromosomes[ ]To make sure daughter cells are genetically different from the parent cell[ ]To allow cells to respond to cues from their internal state and from their environment.arrow_forward
