13.2 Ribosomes And Protein Synthesis Flashcards
Polypeptides
Long chains of amino acids (polymers)
As many as how many different amino acids are commonly found in polypeptides
20
The specific amino acid in a polypeptide chain And the order in which they are joined determines the
Shape and functions of different proteins
Genetic code
The language of genes which is made of A C G T (for dna) these letters are read in sets of three
Is there only one genetic code
No there are multiple genetic codes for codons and anticodons etc.
In DNA one word is called a
Triplet
In mRNA one word is called a
Codon
In tRNA one word is called an
Anti codon
All three types of words (Triplets codons and anticodons)
Complement each other
For every DNA triplet mRNA codon and tRNA anticodon you have one amino acid because of
Translation
How many possible three base codons are there
64 (4x4x4)
Wobble effect
Hypothesis at the third base is not very important because multiple codons can code for a single amino acid
Synonyms
Amino acids that can be the outcome of more than one codon
What do you use to decode codons
Genetic code table
How many stop codons are there
