Question

Slide the mRNA to the right (so that tRNA2 is on the Psite ) and fit the third mRNA codes and tRNA anticodes to form a peptied bond creating a module of tripeptide. At about the Same time that the second peptide bond is forming the first tRNA is released from both the mRNA and the first amino acid. Eventually, it il pick up another specific amino acid What amino acid will tRNA1 pick up? YOU have created a short polypeptide . Polypeptides may be thousands of amino acids in length. As you see, the amino acid sequence is ultimately determine by DNA, because it was the original source of the information Finally lets turn out attention to the concept of a gene. Agene is a unit of inheritence. Our current understanding of a gene is that a gene codes for one polypeptide . This is appropriately called the one - gene, one polypeptide hypothesis. Given this concept , do you think a gene consist of one, several, or many A gene probably consist of deoxyribonucleotiedes Please disassemble your models and return them to the proper location.

Explanation / Answer

10. tRNA1 will pick up amino acid 1 from the amino acid pool of the cell's cytoplasm; since a tRNA is specific for a specific amino acid- it is determined by the anticodon present in it.

11. A gene consists of many deoxynucleotides;

(a gene is a part of DNA ( at least > 250 bp) which is transcribed into mRN which is then translated into Peptides)
