Ms-ls3-1 develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism [clarification statement: emphasis is on conceptual understanding that changes in genetic material may. The structure of dna and rna dna is a double helix, while rna is a single helix both have sets of nucleotides that contain genetic information. The two main functions of the genetic material in a cell, also known as dna, are gene expression and replication dna accomplishes gene expression by providing the instructions necessary for cell.
