macro-nucleic acids

ap bio unit one powerpoint 3

TermDefinition
elements in nucleic acids -Carbon -Hydrogen -Oxygen -Nitrogen -Phosphorus
monomers of nucleic acids -nucleotides
nucleic acids function -store hereditary information -transmit hereditary information -express hereditary information
forms -Deoxyribonucleic Acid (DNA) -Ribonucleic Acid (RNA)
nucleotides -nucleotide to polynucleotide to nucleic acid -three parts -nitrogenous base -five carbon sugar -phosphate group (each monomer has one phosphate group)
polymer of nucleic acids -polynucleotide
nitrogenous base -pyrimidines and purines
pyrimidines -one ring with six atoms -Cytosine -Thymine (only DNA) -Uracil (only RNA)
purines -two rings -six atoms on one, five on another -Adenine -Guanine
5 carbon sugar -sugar bonded to nitrogenous base -Deoxyribose and Ribose -differ in structure and function
sugar in DNA -deoxyribose
sugar in RNA -ribose
phosphate group -phosphate group added to five carbon sugar -attaches to base -forms nucleotide
polynucleotides -phosphate group links nucleotides with phosphodiester linkage -determines directionality (5' to 3')
sequence of bases -unique to gene -determines Amino Acid sequence -determines protein structure
Deoxyribonucleic Acid (DNA) -two polynucleotides form double helix -strands are antiparallel -held together by hydrogen bonds -Cytosine bonds to Guanine -Adenine bonds to Thymine
Ribonucleic Acid (RNA) -single strand polynucleotide -varies in shape -Adenine bonds to Uracil -Cytosine bonds to Guanine

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.
