Week 23 Protein Synthesis : RNA


Feb 9 2015

quote for the day : You know when you’re in love when you can’t fall asleep because reality is finally better than your dreams.” — Dr. Seuss

essential question of the day : what are the main differences between DNA and RNA ?

Learning objectives for the week

LS1.A: Structure and Function

All cells contain genetic information in the form of DNA molecules. Genes are regions in the DNA that contain the instructions that code for the formation of proteins. (secondary to HS-LS3-1) (Note: This Disciplinary Core Idea is also addressed by HS-LS1-1.)
LS3.A: Inheritance of Traits

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.

Protein Synthesis
Thymine changes to Uracil
1) mRNA (messenger RNA) transcription creates the message using codons ( 3 linked amino acids) together like AUG or GAG – mRNA moves out of the nucleus with the instructions for building a protein and into the cytoplasm followed by the ribosome
2) tRNA (transfer RNA) translates the message into a codon and a 3 nucleotide sequence that is read by rRNA which is necessary to create the protein
3) rRNA (ribosomal RNA) molecule that moves the message along to a create a chain ( like a conveyer belt) to create a protein
smallest protein is insulin which is 51 amino acids long, so how many nucleotides does it have?

quote for the day : A dream you dream alone is only a dream. A dream you dream together is reality.” — John Lennon

essential question of the day : what are some mutations that can occur during transcription or translation?

essential question of the day : how do mutations increase variety and diversity to a species and increase survival?
