Lecture 10/14/11

Biol200

QuestionAnswer
Deoxyribonucleic Acid DNA, information
Ribonucleic Acid RNA, information, energy carriers, catalysts.
Nucleotide (monomer) Phosphate, Nitrogenous base, ribonucleotide.
Pyrimidines Cytosine, thymine (only in DNA), uracil (only in RNA).
Purines Adenine, guanine.
Base pairing A-T has 2 hydrogen bonds, A-U in RNA. G-C has 3 hydrogen bonds.
Polymer Strand of nucleic acid. Nucleic acids have polarity. New nucleotides always added to 3' end!
Making activated nucleotides Deoxycytosine mono phosphate dCMP + ATP>ADP = dCDP +ATP>ADP = dCTP no oxygen put a (d) in front
Double stranded Nucleic Acid -H bonds between strands hold them together. -Always anti-parallel. -One strand of DNA is "Complementary" to the other.
The Double Helix Structure is due to the "torsion" (twisting) of phosphodiester bonds. Sugar deoxyribose phosphate
Chromosome One very long DNA double helix and associated protein. In prokaryotes, usually only 1 chromosome and it is circular. In eukaryotes, linear usually many. Human has 46 (23 pairs).
Central Dogma The long-accepted hypothesis that information in cells flows in one direction: DNA codes for RNA, which codes for proteins. Exceptions are now know (e.g. retroviruses).
Central Dogma cont. Information transcribed from DNA to RNA (single stranded), then either functional or information translated.
Gene Codes for a single RNA molecule. Only one DNA strand is used as a template for making RNA.
How are genes different? Different nucleotide sequences, different lengths, and orientation.
Promoter Sequence of nucleotide that indicates beginning of gene.
Terminator Ending of sequence.
DNA Strands are always anti-parallel.

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.
