6.4 - Translation and Protein Synthesis

What is the genetic code?

• code used to translate nucleotide seuqences into amino acids sequences

• group of 3 RNA nucleotides

• the transcription of codons from nucleotide sequences

• the replication of DNA nucleotides to create two identical, semiconservative DNA strands

Organize these options into the right categories

Groups:

(a) Codon

,

(b) Universalness

,

(c) Specificity

,

(d) Redundancy

• 3 RNA nucleotides that code for an amino acid

• each codon gives the same amino acid

• used in nearly all living organisms

• multiple codos give same amino acids

(c) amino acids

,

(d) ribosome

• connects amino acids to create polypeptides

• brings codon to ribosome

• specified by codons

• has an anticoding biding site

• monomers of peptides

• brings amino acid to ribosome

All of the following classify a ribosome except

• protein building factory

• has EPA sites

• is made up of proteins and rRNA

• composed of a large and small subunit

• duplicate genes

Organize these options into the right categories

Groups:

(a) E site

,

(b) P Site

,

(c) A Site

• 2nd site

• Exit

• amino acid intrance

• Polypeptide chain making

• 3rd site

• 1st site

Organize these options into the right categories

Groups:

(a) Beginning

,

(b) Elongagtion

,

(c) Termination

• tRNA pass through ribosome sites

• Ribosome binds to start codon and fits tRNA in A site

• amino acids catalye to make peptide

• stop codon forces ribosome to release

• peptide released into cytoplasm for protein folding

• 1st tRNA enters with a start codon

• 1st tRNA shifts to P site
