DNA/RNA Basics

Genetics - DNA/RNA Basics

QuestionAnswer
describe the structure of dTTP Three phosphate ions, a Deoxyribose sugar, and Cytosine Ion
(chemically) what is the structural difference between DNA and RNA RNA has a hydroxyl group on Carbon 2'
what is the correct order of atoms in a phosphodiester linkage in a DNA strand? 3'C-O-P-O-5'C
what are the bases that might be found convalently linked to a ribose sugar in a polynucleotide chain adenine, cytosine, guanine, uracil
the bases ______________ and _________________ are purines adenine and guanine are purines
which nucleotide bases are pyrimidines uracil, cytosine, thymine
DNA Forms a three-dimensional structure, such as is found in _____________ DNA Forms a three-dimensional structure, such as is found in CHROMOSOMES
Nucleotides are linked together in a linear manner to form a ____________________ of DNA Nucleotides are linked together in a linear manner to form a STRAND of DNA
Two strands of DNA interact with each other to form a double _____________________ Two strands of DNA interact with each other to form a double HELIX
the repeating structural unit of nucleic acids are _____________________ the repeating structural unit of nucleic acids are NUCLEOTIDES
Which is the most stable combination (A/T Pair or G/C Pair)? Why? G/C pairs are more stable because G/C forms three hydrogen bonds while A/T Pairs form two hydrogen bonds
the two strands of DNA are antiparallel this means that, the two strands have opposite orientation of their 5' and 3' ends
how many base pairs would be expected withing three turns of a molecule of DNA 30 base pairs in three turns
(B DNA/Z DNA) is the predominant form found in living cells B DNA is found mostly in living cells
what is an advantage of negative super coiling in bacteria is that it promotes strand separation in small regions enhancing DNA replication
prokaryotic topoisomerase I functions to relax negative super coiling

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
