Unit 9 DNA Vocab

TermDefinition
A building of nucleic acids, consisting of a five-carbon sugar covalently bonded to a nitrogenous base & one/more phosphate groups. Nucleotide
In a polynucleotide (DNA/RNA), the alternating chain of sugar & phosphate to which nitrogenous bases are attacked Sugar-phosphate backbone
A double-stranded helical nucleic acid & the nitrogenous bases adenine, cytosine, guanine, & thymine. Capable of replicating; is an organism's genetic material. Deoxyribonucleic Acid (DNA)
Single-ring nitrogenous bases found in DNA Thymine and Cytosine
Double-ring nitrogenous bases found in DNA & RNA. Adenine & Guanine
A single-ring nitrogenous base found in RNA Uracil
Form of native DNA, referring to its two adjacent polynucleotide strands interwound into a spiral shape. Double helix
Made the first molecular DNA model Watson & Crick
Discovered the double helix of DNA and got a picture of it Rosalind Franklin
A large molecular complex that assembles DNA nucleotides into polynucleotides using a preexisting strand of DNA as a template DNA Polymerase
An enzyme essential for DNA replication that catalyzes the covalent bonding of adjacent DNA polynucleotide strands, used in genetic engineering to paste a specific piece of DNA containing a gene of interest into a bacterial plasmid/other vector. DNA Ligase
Synthesis of RNA on a DNA template Transcription
Synthesis of a polypeptide using the genetic information encoded in an mRNA molecule, change of "language" from nucleotides to amino acids Translation
A three-nucleotide sequence in mRNA that specifies a particular amino acid/polypeptide termination signal; basic unit of the genetic code Codon
Type of ribonucleic acid that encodes genetic info from DNA & conveys it to ribosomes, where the info is translated into amino acid sequences mRNA
On a tRNA molecule, a specific sequence of three nucleotides that is complementary to a codon triple on mRNA Anticodon

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.
