Document Summary

Serves as the instruction manual for all necessary functions the organism possesses. The haploid set of chromosomes in a gamete/ microorganism, or in each cell of a multicellular organism. The complete set of genetic material present in a cell / organism. Individuals instructions stored in the genome are dna sequences called genes. The process of making a copy of a gene into rna. Illustrate the fundamental process and mechanism of cellular transcription and translation through hands-on simulations. Objectives: understand the fundamental processes of cellular transcription and translation, understand the effects of different types of mutations with regard to protein translation. Unit of heredity that is transferred from a parent to offspring and is held to determine some characteristics of the offspring. Refers to the sequence of dna that is copied during the synthesis of mrna. The form of rna in which genetic info. Dna as a sequence of bases is transferred to a ribosome.

Understanding graphs is an important skill in science, since being able to visually depict data is often useful for identifying patterns, and can sometimes be the only tool for easily evaluating whether or not the data supports your hypothesis. When viewing a graph, the______ is plotted on the______, and the______we are measuring is plotted on the_____. For example, in one of the photosynthesis experiments last week, temperature was the______, while the size of the bubble at the end of the experiment was the_____
