BIOL 2317 topic 3

QuestionAnswer
What are polypeptides composed of Amino acid chains
What is the genetic code? Relationship between mRNA and amino acids thats translated 5' to 3'
What doe the genetic code produce? Proteins that have an amino terminus and carboxyl terminus
How is the genetic code read? In triplets, non overlapping, no gaps
Amino terminus N terminus, first amino acid added
Carboxyl terminus C terminus, last amino acid added
Evidence code is non overlapping. 1. overlapping code would change three consecutive codons with each base mutation 2. Nonoverlapping code would change one codon with each base mutation
Polypeptide structures Primary, secondary, tertiary, quaternary
Primary polypeptide structure Sequence of amino acids in the polypeptide chain
Secondary polypeptide structure Form due to hydrogen bonding between different amino acids in the chain, includes alpha helix and beta pleated sheet
Tertiary polypeptide structure Results from R-group interaction of different amino acids, depends on primary and secondary structure
Quaternary polypeptide structure Contains two or more polypeptides
Ribosomes essential tasks in all domains 1. Bind mRNA and identify short codon 2. Facilitate complementary base pairing of mRNA codons and corresponding tRNA codons 3.Catalyze peptide bond formation
Ribosome composition RNA and proteins
Peptidyl site Hold tRNA to polypeptide its attached
Aminocyl site Binds new tRNA containing ammino acid to be added to growing polypeptide chain
Exit site Provides exit for tRNA after its amino acid has been added to the chain

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
