Drag the tiles to the correct boxes to complete the pairs. Recall how Newton’s investigation of light followed one form of the scientific method. Match the statements about Newton’s experiment with the steps in the scientific method. Tiles: White light becomes a spectrum of seven colored lights after passing through a prism. What happens to a single color of light when it passes through a prism? A single color of light will not change when it passes through a prism. White light passes through a prism. A slit is used to direct only the red light through a second prism. When the red light goes through a second prism, its color does not change. The hypothesis proposed for this experiment is true. The colors in a spectrum are part of white light, and the prism separates them. Pairs: Make an observation. Ask a question. Construct a hypothesis. Test the hypothesis with an investigation. Analyze the data. Confirm whether the hypothesis is true. Explain the results.

answer; i believe that the correct answer is (b) melosis; plz check first.good luck

the sugar-phosphate backbone forms the structural framework of nucleic acids, including dna and rna. this backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.

c) 50% there are four chromosomes. after crossing over, 2 of the four have been changed. that means any gamete has a 2 in 4 chance or 50% chance of receiving the mutated chromosome.
