Need quick on a time limit using all my ! 1). identify 3 enzymes involved in dna replication and what they do. 2). this is not the complete sequence of amino acids for the protein luciferin; that is over 900 nucleotides long! however, you did sequence the first ten amino acids in the protein. if you had sequenced all 900, what would be a codon that you would expect to see at the end? 3). chains of amino acids are sometimes called polypeptides. what types of bonds hold the amino acids together? 4). in your own words, describe the flow of information beginning with dna and all the way into a protein

The correct answers are as follows:
1. DNA replication is the process by which two identical DNA molecules are produced from one original DNA molecule. Many enzymes are involved in DNA replication and three of them are listed below: 
a. Helicase: it unwinds the DNA helix.
b. Ligase: it joins together the okazaki portions of the DNA molecule.
c. DNA polymerase lll: it synthesis nucleotides in the five prime to three prime direction.
2. If you had sequence all the 900 nucleotide that are in the protein, the last codon will be a stop codon. The stop codon is also called a terminating or nonsense codon. The typical stop codon for protein are three and they are: UAA, UGA and UAG. Any of these three stop codon can be the last codon in the protein sequence.
3. The type of bond that hold the amino acid together is called PEPTIDE BOND. Peptide bond is usually formed between the alpha carboxyl group of one amino acid and alpha amino group of another amino acid. Amino acids are linked through peptide bonds to form polypeptide chains.
4. When the process of protein synthesis is initiated, the DNA molecule, which is found in the nucleus undergoes transcription process, through which its information is copy into a single stranded RNA. The RNA moves into the cytoplasm to link up with the ribosomes. The RNA then goes through the ribosome three bases at a time and the transfer RNA [tRNA] match up the DNA bases. tRNA then releases the newly produce amino acid, which join the chain of amino acids that are been produced.
