It is false that all amino acids are specified by only one codon. The codon is simply the language that is used to relay information concerning the messenger ribosomal nucleic acid.

Where are condons located?
Condons are in DNA and RNA. Condons are a three-nucleotide sequence that encodes an amino acid or signifies a start signal or stop signal.
How many bases do codons have?
Codons are made up of three bases/nucleotides in DNA or mRNA. Each codon encodes an amino acid or signifies a stop signal. Hope that helps!
Specific function of a protein is determined by?
exact sequence of amino acids
Why is it important that a signal to stop translation be part of protein synthesis?
They signal to stop protein synthesis and release the amino acid chain. Stop codons are important because they signal the end of synthesis. Sometimes, mRNA is longer than what is needed for the amino acids so without stop codons, synthesis would continue until the end of the strand of RNA, leaving you with an incorrect amino acid chain.
A certain protein is made up of 100 amino acids What is the smallest number of bases in the messenger RNA molecule that is needed to carry the code for the synthesis of this protein?
for mRNA, it takes 3 bases (A codon) to signal that a specific amino acid should be used. In this case you would need 100x3 = 300 bases.

Which molecules match mRNA codons to specific amino acids?
Starting from the translation start codon in the mRNA molecule, each three bases corresponds to a single amino acid, until you reach the stop signal. Some amino acids have more that one triplet that codes for them (redundancy). Some parts of the mRNA molecule are untranslated and therefore do not correspond to amino acids.
What is the start signal that begins the assembly of amino acids into a polypeptide chain?
AUG.
How do hydrophobic amino acids and hydrophilic amino acids cause proteind to have a specific shape?
yes

What is used to represent a specific amino acid?
Usually a single letter code, or a 3 letter code. I've attached a link with both.
Which type of Rna can only bond to one specific type of amino acid?
transfer RNA. (tRNA) it "picks up" an amino acid at the top and the two are connected by a hydrogen bond.
