DNA

QuestionAnswer
What is the purpose of DNA Store heriditary information
What does DNA stand for Deoxyribose nucleic acid
What is a nucleotide deoxyribose (sugar), phosphate and nitrogen base
What is DNA made of chains of nucleotides
What type of bonds hold the two strands together hydrogen
What type of bonds holds the nucleotides together covalent
How many bonds are between cytosine and guanine three
How many bonds are between adenine and thymine two
What is the base pairing rule complimentary bases will pair together
What nitrogen bases pair together adenine with thymine and cytosine with guanine
which bases are pyrimidines cytosine and thymine
which bases are purines adenine and guanine
who discovered the shape of DNA Watson and Crick
what is the shape of DNA double helix
What is the purpose of replication copy entire DNA for mitosis
What is semi conservative replication two copies made are each made with one old strand and one new strand
What must happen first Nitrogen bases must separate
what does helicase do breaks hydrogen bonds between the nitrogen bases
what does DNA polymerase do adds nucleotides
What is a replication fork point where two strands of DNA separate for replication
replicate this strand of DNA to DNA: CGTTAC GCAATG
What is purpose of transcription make a working copy of DNA, carries hereditary information from nucleus to ribosome
Transcribe this from DNA to mRNA: TACCGG AUGGCC
Where does transcription occur nucleus
What are three types of RNA mRNA, tRNA, rRNA
What is the function of mRNA template for assembly of proteins
What is the function of tRNA bonds to one specific amino acid and transfers it to ribosome
What is the function of the rRNA Part of the ribosome
What are four main differences between DNA and RNA rna has uracil instead of thymine, single stranded instead of double, made of ribse instead of deoxyribose, short not long
what would the DNA look like that this mRNA originated: CCA GAA UUG GUG GGT CTT AAC CAC
What is translation? protein synthesis
What is a codon? nucleotide triplet found on mRNA, codes for a specific amino acid
What is anticodon found on tRNA, matches complimentary mRNA
What would be the amino acids for the following mRNA sequence: CCA GAA UUG GUG Arg Glut Leuc Val
Where does translation take place? ribosome

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.
