Hypothesis - Tentative explanation for an observation, phenomenon, or scientific problem that can be tested by further investigation Variable - To vary or change Independent Variable - A manipulated variable in an experiment or study whose presence or degree determines the change in the dependent variable (thecause) Dependent Variable - The observed variable in an experiment or study whose changes are determined by the presence or degree of one or more independent variables (the effect) C...

Biology LEAP 2025 Review Study Guide with Complete Solutions The steps in protein synthesis (5) 1. transcription; When a copy of one side of the DNA strand is made, which is mRNA. 2. translation; mRNA moves from the nucleus, to the cytoplasm and then the ribosome. mRNA directs the formation of a specific protein at a ribosome, where the code in the mRNA is converted into an amino acid sequence in a protein. 3. mRNA goes through ribosome 3 bases at a time. 4. tRNA matches with the ope...
