as a purine or a pyrimidine:a. Uracil (U)b. Guanine (G)
Identify each of the bases in problem
17.1 as a component of DNA only, RNA
only, or both DNA and RNA.
17.2 as a component of DNA only, RNA
What are the four bases in DNA and
RNA?
What are the names and
abbreviations of the four nucleosides in
Identify each of the following as a
nucleoside or a nucleotide:a. adenosineb. deoxycytidinec. uridined. cytidine monophosphate
nucleoside or a nucleotide:a. deoxythymidineb. guanosinec. deoxyadenosine monophosphated. uridine monophosphate
State whether each of the following
components is present in DNA only, RNA
only, or both DNA and RNA:a. phosphateb. ribosec. deoxycytidine monophosphated. adenine
only, or both DNA and RNA:a. deoxyriboseb. guanosine monophosphateC. uracild. UMIP
In the genetic disease adenosine
deaminase deficiency, there is an
accumulation of adenosine. Draw the
condensed structural formula for
deoxyadenosine monophosphate.
In the genetic disease uridine
monophosphate synthase deficiency,
symptoms include anemia, cardiac
malformations, and infections. Draw the
condensed structural formula for uridine
monophosphate.
In Lesch-Nyhan syndrome, a
deficiency of the enzyme guanine
transferase causes an overproduction of
uric acid. Draw the condensed structural
formula for guanosine monophosphate.
A deficiency of the enzyme adenine
transferase causes a lack of adenine for
purine synthesis and a high level of
adenine in the urine. Draw the condensed
structural formula for adenosine
