Step 1: State the problem description: define the problem as clearly as possible. Example: The front brakes are making a loud noise.
Step 2: Gather information description: Gather data about the problem and make good observations using all 5 senses. Example: He checked all his other songs and found they all did the same thing.
Step 3: Form a hypothesis description: a prediction that can be tested. Example: Luke decided he would try a different set of headphones and see if that helped.
Step 4: Test the hypothesis description: Use an experiment to test your logical answer to the problem. - Use controlled conditions to test your hypothesis A. Controlled experiment: Everything in an experiment that is the same except for the variable. ~ Variable: Something in an experiment that you change, only one per experiment. ~ Constant: Factors in an experiment that stay the same. Example: Luke asked to borrow 3 diffetent friends' headphones. All the headphones were the same brand. After switching the ears, he found all the headphones worked. However, Luke tried the headphones in his friend's ipod and found they didn't work.
Step 5: Analyze Data description: go over all the data you have and go over conclusions. Example: Luke wrote down all his findings and read over all his notes.
Step 6: Draw a conclusion description: Based on data and observations, conclude the answer to your hypothesis. - should be logical answers to the question based on data and observations. - if needed, retest this theory ( possibly with a new hypothesis) Example: Luke concluded with his data and and observations that his headphones were broken and he needed a new pair.
Step 7: Share results description: report journal to classmates, or publish a journal of findings. Example: Luke shared his findings with his mom and friends, and his mom bought him another pair for his birthday.
Nucleolus is not connected to the nucleus via nuclear pores. <span>Nuclear pores are protein complexes that cross double membrane of the nucleus and allow the transport of molecules across the nuclear envelope (double membrane): from the nucleus to the cytoplasm (RNA and ribosomal proteins) and into the nucleus (proteins, carbohydrates, signalling molecules and lipids).</span>
RNA polymerase, a chemical in the cell, is answerable for making mRNA from the right quality. RNA polymerase is like DNA polymerase, yet it makes a RNA strand as opposed to a DNA strand. The promoter region of DNA Helix is attached by RNA polymerase.
It pulls in nucleotides that supplement those on the DNA strand containing the gene of interest. RNA polymerase duplicates one strand of DNA to make a stretching bit of singlestranded mRNA. RNA polymerase makes the mRNA strand in what is known as the 5' to 3' course.
