"Life Science (9th Grade) DNA/RNA & Protein Synthesis"
Life Science (9th Grade) DNA/RNA & Protein Synthesis Life Science Indicators LS 5 Indicator: Illustrate the relationship of the structure and function of DNA to protein synthesis and the characteristics of an organism. I can . . . o Identify the parts of a nucleotide and explain how nucleotides are linked together to make DNA, following the model proposed by Watson and Crick. o Identify the part of the DNA molecule that actually contains the genetic information. o Compare and contrast the structure of a DNA and RNA. o Relate the DNA molecule to chromosome structure and genes. o Explain how DNA is replicated including the materials needed for the process and tell what is accomplished by it. o Contrast the process of transcription to DNA replication. o Outline the events in the process of translation (protein synthesis) and explain the involvement of mRNA, rRNA, tRNA, and the ribosome. o Tell what a codon and anticodon is and what each represents. o Identify the location within the cell: …where DNA instructions are located, …where replication and transcription take place, & …where translation occurs. LS 7 Indicator: Describe that spontaneous changes in DNA are mutations, which are a source of genetic variation. When mutations occur in sex cells, they may be passed on to future generations; mutations that occur in body cells may affect the functioning of that cell or the organism in which that cell is found. I can . . . o Explain the relationship between genes and proteins. o Explain the significance of mutations to living things. o Contrast gene mutations and chromosome mutations. o Show how point mutations & frame-shift mutations affect DNA sequences differently, and explain how each affect the synthesis of proteins. o State how the consequences of a mutation in a sperm or egg cell differ from that of a body cell. o Compare the effects of different kinds of mutations on cells and organisms and categorize the effects as harmless, harmful, lethal, and even helpful.
