In his transformation experiments, what did Griffith observe? b. Mixing a heat-killed pathogenic strain of bacteria with a living nonpathogenic strain can convert some of the living cells into the pathogenic form. Cytosine makes up 42% of the nucleotides in a sample of DNA from an organism. Approximately what percentage of the nucleotides in this sample will be thymine? a. 8% At a specific area of a chromosome, the sequence of nucleotides below is resent where the chain opens t...

How does substrate/enzyme concentration affect enzymatic activity? - ️️If there is too much substrate compared to the enzyme, enzymatic activity will plateau Increasing the amount of enzymes will increase the rate of enzymatic activity How do enzymes catalyze reactions? - ️️By forming a substrate-enzyme complex. The enzyme brings the substrates together and put stress to break the bonds. Enzymes create a micro-environment or break bonds What is a catalyst? - ️️A substance that ...
