Describe briefly what is occurring at each step in the figure. Ans: This figure represents protein synthesis. Step one the initiator tRNA attaches to a start codon. In step two the large and small ribosomal subunits join to form a functional ribosome and initiator tRNA fits into P site. In step three the anticodon of an incoming tRNA pairs with the next mRNA codon at A site. Step four the amino acid on the tRNA at P site forma a peptide bond with the amino acid at A site. Step five the tRNA at the P site leaves the ribosome and the ribosome shifts down by one codon. The tRNA previously at the A site is now at the P site. Step six is when protein synthesis stops when the ribosome reaches one of three stop codons on the mRNA strand.

Difficulty: medium Test Bank - Principles of Anatomy and Physiology, 12th Edition, by Bryan Derrickson, Gerald Tortora. Feedback: 3.3 62. Compare mitosis to meiosis. Ans: Mitosis is the division of nuclear contents of the cell. Mitosis is preceded by replication of DNA. During mitosis the two copies of DNA are separated into two different cells. Those two cells are identical to the original cell. Mitosis occurs in somatic cells and is necessary for growth and repair. Meiosis is the type of cell division that produces the gametes, the ova and sperm. Just as in mitosis, replication of DNA occurs before meiosis so that each chromosome is doubled. However, during meiosis, there are several differences from mitosis. During prophase I of meiosis, the homologous chromosome synapse and may exchange portions in a process called crossing-over. By the end of meiosis I, the homologs have been separated into different cells. These new cells are called haploid because they only contain one of the two homologs. Immediately after meiosis I, another round of division occurs and separates the sister chromatids in each cell. At the end of meiosis II, there are four cells. Each of those cells contains just 1 copy of each chromosome. Difficulty: medium Feedback: 3.7 Test Bank - Principles of Anatomy and Physiology, 12th Edition, by Bryan Derrickson, Gerald Tortora.
