Genetics Terms

Genetics terms for Bio 121

TermDefinition
restriction enzyme an enzyme that cuts a DNA strand wherever it finds a specific short sequence of base pairs
gel electrophoresis a method of separating macromolecules by size and charge by using electrical attraction to pull the molecules through a porous gel
PCR Polymerase chain reaction. A technique to amplify DNA by repeatedly cycling through rounds of denaturing DNA, annealing specific primers flanking the site to be amplified, and copying DNA with a polymerase.
CRISPR-Cas9 A gene editing tool that allows DNA sequences to be altered in almost any way desired in a living cell.
transcription The copying of a gene in a cell’s DNA into an RNA transcript.
intron A sequence in a eukaryotic gene that is transcribed but will not be translated. Introns must be spliced out of the raw mRNA transcript before it leaves the nucleus to be translated.
Poly-A tail A sequence of adenine (A) nucleotides added to the end of eukaryotic mRNA transcripts before they leave the nucleus for translation - length of the poly-A tail determines how many times the mRNA can be translated before it is degraded in the cytoplasm
degenerate code A code in which there is not a one-to-one correspondence between code signals and their translations.
tRNA A small RNA molecule that binds to a specific amino acid and to a specific codon in an mRNA molecule. tRNA molecules act as the means for the ribosomes to assemble a polypeptide with the correct amino acids specified in the mRNA code.
operon A set of genes in a prokaryote that are adjacent to each other and that share a common promoter and regulatory mechanisms.
in-situ hybridization A method for detecting gene expression in tissues by binding an RNA probe (labeled with a dye or fluorescent marker) to mRNA in a fixed tissue sample. It allows detection of gene expression in a specific tissue at a specific point in time.
translation The reading of an mRNA code by a ribosome and tRNA molecules and the resulting construction of a polypeptide based on that code.

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.
