QuestionAnswer
Use a Venn diagram to compare and contrast DNA and RNA Comparing similarities and differences between DNA and RNA
Explain the base-pairing rules of DNA A pairs with T; C pairs with G
Draw a nucleotide and label its parts Nucleotide contains sugar, phosphate, base
Explain the difference between purines and pyrimidines Purines: A,G (2 rings); Pyrimidines: C,T (1 ring)
Explain the structure of a DNA molecule Double helix with complementary base pairs
Summarize the process of DNA replication DNA unwinds and is copied by enzymes
Describe the difference between leading and lagging strands Leading continuous; lagging uses Okazaki fragments
Explain why DNA replication is semi-conservative Each new molecule has one old strand and one new strand
Identify a nucleic acid as DNA or RNA Based on structure or description
Predict a consequence of an error during DNA replication Mutations such as base changes or protein alteration
Explain the central dogma and why a two-step process is needed DNA → RNA → Protein; transcription then translation
Describe the roles of the three types of RNA mRNA = message; tRNA = carries amino acids; rRNA = ribosome
Summarize the steps of transcription and translation Transcription makes mRNA; translation makes proteins
Transcribe and translate the DNA strand TACACCGGAGGCTTTATT Produce the corresponding mRNA and amino acid sequence
Explain how mRNA is modified after transcription Capping, tail addition, intron removal
Describe an example of gene expression regulation Controlled by enhancers, repressors, methylation
Explain the difference between epigenetics and mutations Epigenetics changes expression; mutations change DNA
Predict a consequence of an error in transcription or translation Incorrect or nonfunctional protein
Describe the difference between somatic cells and gametes Somatic = body cells; gametes = sex cells
Differentiate between autosomes and sex chromosomes Autosomes = non-sex chromosomes; sex chromosomes determine sex
Explain why cells going through meiosis divide twice To reduce chromosome number and produce haploid cells
Differentiate the purpose and results of meiosis I and II Meiosis I separates homologous pairs; II separates chromatids
Explain the significance of crossing over Creates genetic variation
Sketch each phase of meiosis and describe key events Phases show crossing over, alignment, separation events
Summarize differences between meiosis and mitosis Meiosis creates gametes; mitosis creates identical cells
Explain the difference between mistakes in meiosis vs mitosis Meiosis errors cause chromosomal disorders; mitosis errors affect growth
Identify a cell as haploid or diploid Haploid = one set; diploid = two sets
Predict a consequence of an error in meiosis Disorders such as nondisjunction or abnormal gametes

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.
