Universal Ancestor Domain Bacteria Domain Archaea Domain Eukarya (Eubacteria) (Archaebacteria) (Eukaryotes) Unit 10 (Vertebrates, Basic Animal Structure and Function) 39.

Describe the chemical composition and configuration of enzymes and discuss the factors that modify enzyme structure and/or function. After an enzyme is mixed with its substrate, the amount of product formed is determined at 10-second intervals for 1 minute.

Data from this experiment are shown below: Unit 3 (Cell Structure and Function, Cell division) 5. A laboratory assistant prepared solution of 0.8 M, 0.6 M, 0.4 M, and 0.2 M sucrose, but forgot to label them.

Explain how ATP is involved in each example you choose.

Unit 5 (Meiosis, Mendelian Genetics, DNA Replication) 17.

Begin with the separation of the messenger RNA from the DNA template and end with the release of the protein at the plasma membrane. Describe the steps of protein synthesis, beginning with the attachment of a messenger RNA molecule to the small subunit of a ribosome and ending generalized with the release of the polypeptide from the ribosome.

Include in your answer a discussion of how the different types of RNA function in this process. The diagram below shows a segment of DNA with a total length of 4,900 base pairs.

methionine – leucine – glutamic acid – proline – arginine Describe the steps in the synthesis of this polypeptide.

What would be the effect of a deletion or an addition in one of the DNA nucleotides?
