QuestionAnswer
What is DNA? DNA determines an organisms traits and controls the structure of proteins and it depends on enzymes (protein).
What kind of sugar is associated with DNA? Deoxyribose.
What are the nitrogen bases for DNA? Adenine (A), Guanine (G), Thymine (T), Cytosine (C).
Is DNA double or single helix? Double helix.
What is rRNA? Ribosomal RNA makes up part of the ribosomes.
What is tRNA? Transfer RNA attaches to amino acids and moves them during protein synthesis.
What is mRNA? Messenger RNA contains the code of the amino acid sequence.
What is one change that the RNA nitrogen bases have? RNA has uracil instead of thymine.
What kind of sugar is associated with RNA? Ribose.
Is RNA double or single stranded? Single stranded.
What is transcription? Is the process of making RNA from DNA.
What is a codon? Is a sequence of 3 nucleotides on a mRNA strand, each codon codes for a specific amino acid.
What is an anticodon? Is a sequence of 3 nucleotides on a tRNA strand, it is complementary to the codon of mRNA.
What is translation? Where the cell makes proteins out of the genetic info the mRNA brought.
What is point mutation? 1 nucleotide is substituted with another (will affect only 1 amino acid sequence).
What is frame shift mutation? A nucleotide is inserted or deleted (will affect all the amino acids).
What is natural selection? Is a process that causes certain traits to become more common in a population over time.
How does survival of the fittest work? The strongest and most suited to the environment will survive and pass the more favorable trait to its offspring.
What are 2 main impacts of humans on natural selection? Pesticides and antibiotics.
What are examples of innate behaviors? Hibernation and estivation.
What are examples of learned behaviors? Imprinting, animal training, territorial defense.
What is evolution? The process of change over time.
What are homologous structures? Similar bone structures, but different functions. May share a common ancestor.
What are analogous structures? Have similar functions but different structures. Do not share a common ancestor.
What are vestigial structures? Are structures that exist, but are no longer used in an organism.
What is embryology? Is comparing embryonic structures.
Define cytology. Comparing cell structures.
Define biochemistry. Comparing chemical makeup.
What is a node in a cladogram? Is a branching point where lineage splits.

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.
