Checklist for Lecture Exam 1 Chapter 1 ANATOMY : The study of structure PHYSIOLOGY: The study of function. Levels of organization CHEMICAL LEVEL: includes Atoms ( C‚O‚ H‚ N)‚ the smallest units of matter. These 4 are essential to life. Atoms bond together to form MOLECULES. CELLULAR LEVEL: Molecules combine to form Organelles. Organelles function together to form a CELL‚ the smallest unit of life. There are different types of cells with different functions. A cell consists of

Question and Answer 1. Paper reported that Olfm4 deletion induces colon adenocarcinoma in APCmin mice‚ so why after miR-34 deletion‚ olfm4 positive stem cell number was increased and tumor incidence was also increased? Their research was working on the colon tumorigenesis‚ but we are working on the small intestine. Also in our model‚ colon tumor is very rare‚ could because of different genetic background. The function of Olfm4 may be also tissue specific. 2. Do these changes caused by the genetic

Polymers: a chain of many monomers that are chemically bonded together. How are polymers formed? Dehydration Synthesis (Condensation): two hydrogen atoms and one oxygen atom are removed from the monomers to form water‚ and the two monomers are joined together. How are polymers broken down? Hydrolysis—the reverse of dehydration synthesis (condensation) the reverse of dehydration synthesis. Water added to the polymer‚ unlinking the chain and breaking it back down to its original monomer units. Carbohydrates

PROTIEN Question (1): Define and distinguish primary structure‚ secondary and tertiary structures of proteins. Protein Structures: Primary structure Primary structure of protein is its unique sequence of amino acids forming its polypeptide chain. The primary structure of a protein is starting from the amino-terminal (N) end to the carboxyl-terminal (C). Secondary structure Most proteins have segments of their polypeptide chain repeatedly coiled of folded in patterns. These coiled & folded

cell‚ it is actually the MreB protein that facilitates cell shape[citation needed].[3][4] Peptidoglycan is also involved in binary fission during bacterial cell reproduction. The peptidoglycan monomers are synthesized in the cytosol and are then attached to a membrane carrier bactoprenol. Bactoprenol transports peptidoglycan monomers across the cell membrane where they are inserted into the existing peptidoglycan.[11] In the first step of peptidoglycan synthesis‚ the glutamine‚ which is an amino
