Summary Introduction

To explain: The reason for obtaining such DNA fragments that differ in size by a standard amount of about 200 bp,

Introduction: Apoptosis is a process that results in cell death. It is a type of “programmed cell death”. It is observed in the eukaryotic organisms.  It can occur due to damage of DNA, the release of cell death enzymes and so on. Apoptosis is either intrinsic or extrinsic. In intrinsic apoptosis, the cell kills itself due to cell stress. However, in extrinsic apoptosis, the cell receives certain signals from the outside environment to kill itself.

Cell division and apoptosis a) The cell cycle is divided into different phases (named M, G0, G1, S and G2). Can you explain what happens during the different parts of the cycle and how to control it? b) What is the difference between apoptosis and necrosis? c) What are caspases and what is their function in the cell?
Dynamic instability causes microtubules either to grow or to shrink rapidly.  Consider an individual microtubule that is in its shrinking phase. What would need to happen at the end of the microtubule in order for it to stop shrinking and to start growing again?  Be specific! What would happen if only GDP, but no GTP, were present in the solution?        What would happen if the solution contained an analog of GTP that cannot be hydrolyzed?
BIOLOGY ACTIVITY -Gene Mutations and Proteins   Objective:  To demonstrate how gene mutations affect the production of proteins?   Procedure: Use the following base sequence of one strand of an imaginary DNA molecule: AATTGAACACATGCGCCC. 2. Write the base sequence for an mRNA strand that would be transcribed from the given DNA sequence.  Place your results in the table below. Use your codon table provided below to determine the sequence of amino acids in the resulting protein fragment.  Place your results in the table below. If the fifth base in the original DNA strand were changed from G to C, how would this affect the resulting protein fragment?  Write the new protein fragment in the table below. If G were added to the original DNA strand after the third base, what would the resulting mRNA look like?   How would this addition affect the protein?  Show your results in the table below. Data:  mRNA from Step 2   Protein Sequence from Step 3   Protein Sequence from Step…
