How many protein-coding codons are there?
61 codons specify the amino acids used in proteins and 3 codons (stop codons) signal termination of growth of the polypeptide chain...so 64 total
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.
What dictates the corresponding sequence of amino acids in a growing polypeptide chain?
The sequence of amino acids being added to the growing polypeptide chain is controlled by the instructions (codons, 3-base codes) on the mRNA. These are a copy of the coding regions of the gene from the DNA in the nucleus.
What functions are carried out by those few codons tat do not code for amino acid?
They(UAA, UAG, & UGA stop codons) cause the ribosome to stop translating an mRNA
What is the connection between amino acids and protiens?
A codon is a sequence of three nucleotides which is used as the template for translation into amino acids. Three codons will be read to produce one amino acid.
What amino acid chain will be formed by the codons shown below AAG UGA?
Gly Lys Cys
What amino acid chain will be formed by the codons pro cal pro?
Those are not DNA or RNA codons.

Which amino acid chain will be formed by the condons shown below?
asparagine-lysine-aspartic acid
What is formed from the long chain of amino acids?
Proteins are formed from long chains of amino acids.
What is the part of protein synthesis?
Transcription: mRNA is copied from a DNA molecule. Translation: The mRNA molecule then attaches to ribosomes. tRNA carrying amino acids come and attach to Codons on the mRNA. The amino acids bond to form a chain and a protein is formed.

What is the function of a stop condon?
The stop codons (UAA, UAG, UGA) stop the transcription process in forming an amino acid chain and therefore a protein. It signals the end of the chain.
What is the second part of protein synthesis called?
Transcription: mRNA is copied from a DNA molecule. Translation: The mRNA molecule then attaches to ribosomes. tRNA carrying amino acids come and attach to Codons on the mRNA. The amino acids bond to form a chain and a protein is formed.
What is formed when 5 amino acids are joined together?
Polypeptide chain
How do you make proteins?
DNA gets split into single strands, It is then copied to form mRNA. The mRNA is then transported from the nucleus to the cytoplasm where the ribosome binds, reads the mRNA strand and tRNA's carrying amino acids are joined together. The tRNAs bind due to their complimentary nucleotides, each amino acid has a triplicate of codons, all amino acids have different codons that all code for that amino acid. As the amino acid chain grows from the ribosome the protein chain grows.

The sequence of amino acids being added to the growing polypeptide chain is controlled by the instructions (codons, 3-base codes) on the mRNA. These are a copy of the coding regions of the gene from the DNA in the nucleus.
