What function does DNA serve during protein synthesis?

A photon undergoes Compton scattering off a stationary free electron. The photon scatters at

$$90.0 ^ { \circ }$$

from its initial direction; its initial wavelength is

$$4.00 \times 10 ^ { - 12 } \mathrm { m }$$

. What is the electron's kinetic energy?

How does DNA direct protein synthesis from inside the nucleus?

What would most likely happen if the ribosomes in a cell were not functioning? (1) The cell would undergo uncontrolled mitotic cell division. (2) The synthesis of enzymes would stop. (3) The cell would produce antibodies. (4) The rate of glucose transport in the cytoplasm would increase.

DNA replication begins when the double helix untwists and breaks in half between the nitrogen bases. What are the next two steps in the process of DNA replication?

List the six nitrogen bases that would pair with the following sequence of bases in a strand of DNA: T C G A C A

Animal cells utilize many different proteins. Discuss the synthesis of proteins in an animal cell. Your answer must include:\

• the identity of the building blocks required to synthesize these proteins;\
• the identity of the sites in the cell where the proteins are assembled;\
• an explanation of the role of DNA in the process of making proteins in the cell.

How does a single change in a nitrogen base alter the formation of a resulting protein?

What is the purpose of DNA replication?

Write the expression with a rational denominator and in simplest form. $\frac{7}{\sqrt{2}+1}$

Describe the difference between the general solution and a particular solution of a differential equation.
