Get down to the molecular nitty-gritty of DNA replication and protein
synthesis in this article by Dennis O'Neil.
Think all DNA resides in the nucleus? Want to know how to decipher a DNA code into protein? This article, filled with colorful visuals, takes you down to the microscopic level as it explains the workings of DNA, RNA, and proteins inside living cells.
Why do you think DNA exists as a double helix, versus some other shape like a highly folded protein or a linear, single-stranded fatty acid?
In eukaryotic cells, DNA is "trapped" inside two organelles. What are they? Do you think this is simply a biological coincidence, or might there be some benefit to cells that keep their DNA inside these structures?
What is a codon? Do all codons code for amino acids?
How can mutations occur during DNA replication? Can all genetic mutations be passed along from parents to offspring?
Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
