How are DNA and RNA different

Biology
2 answers:
Gnesinka [82]3 years ago
7 0

A few key differences:

  • DNA and RNA are abbreviations for <em>deoxyribonucleic acid </em>and <em>ribonucleic acid</em> respectively. This difference has to do with the fact that DNA contains a sugar called <em>deoxyribose </em>while RNA's sugar is simply <em>ribose</em>.
  • DNA has a <em>double-helical </em>structure while RNA is a single strand (resembling a single strand off a DNA's double helix). See the attached image for an illustration of this structure.
  • The bases of DNA are <em>guanine, cytosine, adenine, </em>and <em>thymine</em>. In RNA, by contrast, thymine is replaced by <em>uracil</em>.
  • Functionally, DNA is a kind of storage unit for genetic information. RNA <em>uses </em>this information to build proteins, copying it from the master copy contained in the DNA and converting it to a form the ribosomes can use.

How are prokaryotes who reproduce by asexual reproduction are NOT able to be very diverse in their genes?
Helga [31]

when a prokaryote reproduces, it will duplicate its self and make another one just like it. like a carbon copy. they dont get to be diverse because they dont reproduce sexually, which would mix up genes making it more diverse.

PKU can result from defects in phenylalanine hydroxylase (PAH), an enzyme that converts phenylalanine into amino acid tyrosine.
Inessa05 [86]

Answer:

Low phenylalanine concentration:

  • If the enzyme is inactive, PAH will look like its inactive form, with phenylalanine located in the allosteric site / inactive site so that PAH is a different shape. This will not allow as much phenylalanine to be converted into tyrosine, as we wait for Phe levels to increase.

High phenylalanine concentration:

  • If the enzyme is active, PAH will look like its regular form, with an open active site that's the size of phenylalanine so that reactions can occur. (Like a hand fitting into a glove, or a lock into a key.) Phenylalanine will be the substrate, the thing acted upon by the enzyme. This will eventually raise the amount of tyrosine that's created and lower the concentration of phenylalanine.

Think about it like this. Ever heard of homeostasis? That's how the body likes to be the same, keep everything regulated, all the time. So if there are high levels of something, the body is going to try to keep that something down, and if there are low levels, it's going to try to increase the concentration of that thing.
