Concept explainers
(a)
Interpretation:
From the given segment of a nucleic acid, it is to be determined whether it is a segment of RNA or DNA.
Concept introduction:
The small molecular units from which
(b)
Interpretation:
From the given segment of a nucleic acid, each nucleotide should be circled and named.
Concept introduction:
Nucleotides are distinguished from one another by identifying the nitrogenous bases attached to the sugar group. In both, RNA and DNA, it is the specific sequence of the nitrogenous bases that determines the genetic information that is stored or carried. There are four types of five nitrogenous bases that could be present in RNA and DNA. Uracil, guanine, adenine, cytosine, thymine are the nitrogenous bases present in RNA and DNA. In a nucleotide, the

- Which of the following is an amino acidarrow_forwardA forensic scientist is trying to find out the number of adenine bases in the DNA sample that he obtained from a crime scene. What can he assume about the number of adenine? O The number of adenine bases will be equal to the number of guanine bases. O The number of adenine bases will be equal to the total of all the other bases. O The number of adenine bases will be equal to the number of thymine bases. O The number of adenine bases will be half of the number of cytosine bases.arrow_forwardThe name carbohydrate comes from the fact that many simple sugars have chemical formulae that look like water has simply been added to carbon. (The suffix hydrate from the Greek word hydor ("water") means "compound formed by the addition of water.") The actual chemical structure of carbohydrates doesn't look anything like water molecules bonded to carbon atoms (see sketch at right). But it is nevertheless possible to chemically extract all the hydrogen and oxygen from many simple carbohydrates as water, leaving only carbon behind. If you search the Internet for "reaction of sulfuric acid and sugar" you will find some impressive videos of this. Suppose you had (200. g) of ordinary table sugar, which chemists call sucrose, and which has the chemical formula C12H₂2011. Calculate the maximum mass of water you could theoretically extract. Be sure your answer has alunit symbol, and round it to 3 significant digits. 0 HO CH₂OH OH OH OH The actual chemical structure of glucose.arrow_forward
