Standards
Next Generation Science Standards (NGSS)
HS-LS3-1: Ask questions to clarify relationships about the role of DNA and chromosomes in coding instructions for characteristic traits passed from parent to offspring
Each chromosome consists of a single very long DNA molecule, and each gene on the chromosome is a particular segment of that DNA. The instructions for forming species’ characteristics are carried in DNA. All cells in an organism have the same genetic content, but the genes used (expressed) by the cell may be regulated in different ways. Not all DNA codes for a protein; some segments of DNA are involved in regulatory or structural functions, and some have no as-yet known function. (HS-LS3-1)
Science Framework for California Public Schools (K-12)
4 - Genetics (Molecular Biology) - Genes are a set of instructions encoded in the DNA sequence of each organism that specify the sequence of amino acids in proteins characteristic of that organism. As a basis for understanding this concept:
4a) - Students know the general pathway by which ribosomes synthesize proteins, using tRNAs to translate genetic information in mRNA.
4b) - Students know how to apply the genetic coding rules to predict the sequence of amino acids from a sequence of codons in RNA.
4e) - Students know proteins can differ from one another in the number and sequence of amino acids.
5 - Genetics (Biotechnology) - The genetic composition of cells can be altered by incorporation of exogenous DNA into the cells. As a basis for understanding this concept:
5a) - Students know the general structures and functions of DNA, RNA, and protein.
5b) - Students know how to apply base-pairing rules to explain precise copying of DNA during semiconservative replication and transcription of information from DNA into mRNA
ELD Standards
Collaborative - 1). Exchanging information and ideas with others through oral collaborative discussions on a range of social and academic topics.
Interpretive - 6a). Reading closely literary and informational texts and viewing multimedia to determine how meaning is conveyed explicitly and implicitly through language.
Productive - 10b). Writing literary and informational texts to present, describe, and explain ideas and information, using appropriate technology.
