| Standard 4: 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:
5a: The general structures and functions of DNA, RNA, and protein.
1d: The central dogma of molecular biology outlines
the flow of information from transcription of ribonucleic acid (RNA) in the
nucleus to translation of proteins on ribosomes in the cytoplasm.
4a: The general pathway by which ribosomes synthesize
proteins, using tRNAs to translate genetic information in mRNA.
5b: Apply base-pairing rules to explain precise copying of DNA during
semiconservative replication and transcription of information from DNA into
mRNA.
4b: Apply the genetic coding rules to predict the sequence of amino acids
from a sequence of codons in RNA.
4e: Proteins can differ from one another in the number and sequence of amino
acids.
*4f: Students know why proteins having different amino acid sequences
typically have different shapes and chemical properties.
4c: Students know how mutations in the DNA sequence of a gene may
or may not affect the expression of the gene or the sequence of amino acids
in an encoded protein.
4d: Specialization of cells in multicellular organisms is usually due to
different patterns of gene expression rather than to differences of the
genes themselves. | |
