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.
