18. DNA (deoxyribonucleic acid) is made of nucleotides. Each nucleotide can contain any one of these nitrogenous bases: A (adenine), G (guanine), C (cytosine), T(thymine). If one of those four bases (A, G, C, T) must be selected 7 times to form a linear septuplet, how many different septuplets arepossible? All four bases can be selected for each of the seven components of the septuplet.
The number of possible different septuplets is____
19. Winning the jackpot in a particular lottery requires that you select the correct three numbers between 1 and 40 and, in a separate drawing, you must also select the correct single number between 1 and 46.
Find the probability of winning the jackpot.____
(Type an integer or simplified fraction.)

Each of the following statements about the structure of DNA may be either true or false. Choose the appropriate answer for each of these statements. Bonding between adenine and thymine on opposite strands involves two hydrogen bonds. Nitrogenous bases are located on the outside of the double helix: phosphates are located towards the middle of the double helix. Bonding between guanine and cytosine on opposite strands involves three hydrogen bonds. DNA and RNA are structurally different due to the difference...

1.)With one method of a procedure called acceptance sampling, a sample of items is randomly selected without replacement and the entire batch is accepted if every item in the sample is okay. A company has just manufactured 1696 CDs, and 614 are defective. If 33 of these CDs are randomly selected for testing, what is the probability that the entire batch will be accepted? Does this outcome suggest that the entire batch consists of good CDs? Why or why not?...

What are the three functional groups that comprise a nucleotide? What do nucleotides have in common with amino acids or simple sugars? When the structure of DNA was first elucidated, many biologists quickly saw how this structure explained the passage of information from one generation to another. How does the structure of DNA explain generation-to-generation flow of information? In other words, give a brief description of the structure of DNA and tell how this structure allows for replication. Which of...
