A double-stranded DNA molecule contains 560 nucleotides. How many complete turns would be found in this double helix?

Which choice lists the parts of the brainstem? a. midbrain, pons, and medulla oblongata b. forebrain, midbrain, and hindbrain c. sulci and fissures d. frontal, parietal, and temporal lobes

the medulla is located directly above the spinal cord in the hindbrain and controls

The brain and the spinal cord make up the (1) autonomic nervous system (2) peripheral nervous system (3) central nervous system (4) somatic nervous system

the part of a neuron that conducts impulses away from its cell body is called a(n)

What parts of a nucleotide (namely, phosphate, sugar, and/or bases) occupy the major and minor grooves of double-stranded DNA, and what parts are found in the DNA backbone? If a DNAbinding protein does not recognize a specific nucleotide sequence, do you expect that it recognizes the major groove, the minor groove, or the DNA backbone? Explain.

Draw the structure of deoxyribose and number the carbon atoms. Describe the numbering of the carbon atoms in deoxyribose with regard to the directionality of a DNA strand. In a DNA double helix, what does the term antiparallel mean?

Make a side-by-side drawing of two DNA helices, one with $10 \mathrm{bp}$ per $360^{\circ}$ turn and the other with 15 bp per $360^{\circ}$ turn.

In what ways are the structures of an $\alpha$ helix in proteins and the DNA double helix similar, and in what ways are they different?

Briefly describe the lytic and lysogenic cycles of bacteriophages. In your answer, explain what a prophage is.

When baking soda

$$(\text{sodium bicarbonate or sodium hydrogen carbonate,}\;\mathrm{NaHCO_3})$$

is heated, it releases carbon dioxide gas, which is responsible for the rising of cookies, doughnuts, and bread.

Write abalanced equation for the decomposition of the compound

$$(\text{one of the products is}\;\mathrm{Na_2CO_3}).$$

(b) Calculate the mass of

$$\mathrm{NaHCO_3}$$

required to produce

$$\mathrm{20.5\;g\;of\;CO_2}.$$

What does the term complementation mean? If two different mutations that produce the same phenotype can complement each other, what can you conclude about the locations of each mutation?

Use the formation of water from hydrogen and oxygen to explain the following terms: chemical reaction, reactant, and product.

Write an unbalanced equation to represent each of the following reactions: (a) Potassium hydroxide and phosphoric acid react to form potassium phosphate and water. (b) Zinc and silver chloride react to form zinc chloride and silver. (c) Sodium hydrogen carbonate reacts to form sodium carbonate, water, and carbon dioxide. (d) Ammonium nitrite reacts to form nitrogen and water. (e) Carbon dioxide and potassium hydroxide react to form potassium carbonate and water.
