7198133051What does the nitrogen cycle do?The nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans.0
7196082746Why is nitrogen important?Nitrogen is an essential component of amino acids and of nucleotides (the building blocks of DNA), and consequently is needed by all living things.1
7198136215What do amino acids do?They build proteins! Proteins are the essential building blocks of all living things.2
7196085029How does it impact food production?The nitrogen cycle reflects a more intimate side of energy needs, via its central role in the production of food. It is one of the places where the chemistry of the Earth and life come together, as plants extract nitrogen from their environment, including the air, to make food. Controlling the impact of agriculture on the global cycle of nitrogen is a growing challenge for sustainable development3
7196088105Will excess fixed nitrogen increase?YES! Globally, until nitrogen fixation is balanced by denitrification, the amount of excess fixed nitrogen in the world will grow relentlessly, with increasing consequences for ecosystems and the public health4

AP Biology: DNA Replication Flashcards

Terms : Hide Images
9553676526Replication BubbleOval opening in DNA, spreads outward in both directions. Replication starts in the middle of a DNA strand, not at the ends!0
9553676527Replication ForkA Y-shaped region were the new strands of DNA are elongating during DNA replication.1
9553676528nucleotide triphosphatesbuilding blocks needed to make new strands of DNA; provide energy for DNA replication by the hydrolysis of bonds between phosphates2
9553676529HelicaseAn enzyme that untwists the double helix at the replication forks, separating the two parental strands and making them available as template strands.3
9553676530Single-Stranded Binding ProteinsProtein that coats single-stranded segments of DNA, stabilizing the DNA so it won't reanneal4
9553676531DNA Polymerase IIIAn enzyme that catalyzes the elongation of new DNA at a replication fork by the addition of nucleotides to the existing chain. Can only read 3' to 5' and build new strands 5' to 3'.5
9553676532Lagging StrandA discontinuously synthesized DNA strand, built in the direction opposite of the replication fork. Must be built in pieces6
9553676533Leading StrandThe new continuous complementary DNA strand synthesized along the template strand in the mandatory 5' to 3' direction.7
9553676534Okazaki FragmentsSmall fragments of DNA produced on the lagging strand during DNA replication, joined later by DNA ligase to form a complete strand.8
9553676535LigaseAn enzyme that connects two fragments of DNA to make a single fragment9
9553676536PrimaseAn enzyme that joins RNA nucleotides to make the primer using the parental DNA strand as a template. Serves as starter sequence for DNA Polymerase III, which will add on the complementary bases.10
9553676537DNA Polymerase IRemoves sections of RNA primer and replaces them with DNA nucleotides. Can still only build onto 3' end of an existing DNA strand.11
9553676538TelomeraseAn enzyme that catalyzes the lengthening of telomeres. The enzyme includes a molecule of RNA that serves as a template for new telomere segments.12
9553676541telomereA specialized region at the ends of eukaryotic chromosmes that contains several repeats of a particular DNA sequence. In cells that lack telomerase, the telomeres slowly shorten with each round of DNA replication; this is thought to contribute to the eventual death of the cell.13
9553676542origin of replicationThe specific location on a DNA strand where replication begins.. Prokaryotes have one, while eukaryotes have several per chromosome.14
9553676543RNA primerstrand of short nucleic acid sequences (generally about 10 base pairs) that serves as a starting point for DNA synthesis. It is required for DNA replication because the enzymes that catalyze this process, DNA polymerases, can only add new nucleotides to an existing strand of nucleic acid.15
