Perform visual comparison of the assigned two putatively related nucleic acid sequences x and y. Indicate in your answer the identities by 1s on match and 0s on mismatches.
Transformation, conjugation, and transduction were discovered in the laboratory. How important are these mechanisms of genetic recombination in nature.
Describe how microfilaments polymerize from their monomer components. Include a description of the protein component(,0) treadmilling, and the role of ATP and capping proteins.
Describe the structure of microfilaments and microfilament networks and explain how they are assembled and disassembled within a cell.
Explain what is meant by the term 'extracellular matrix' and five two example of proteins that may be found in the extracellular matrix.
How is a Scathard plot generated, and what measure of the inter-molecular interaction is used to determine this.
