Biology Chapter 13

Final Review

QuestionAnswer
Genetic Engineering making changes in the DNA code
4 different techniques molecular biologists use to study and change dna molecules extract dna from cells, cut dna into smaller pieces, identify the base sequences, make unlimited copies
How to get DNA out of a cell open the cell and separate the dna from other cell parts
Biologists use these to cut DNA molecules at a specific sequence of nucleotides to make smaller fragments. What are restriction enzymes?
Gel electrophoresis process by which DNA fragments are separated and analyzed. the electric voltage applied to the gel separates the DNA fragments. it is used to compare the genomes of different ogranisms. it can be used to locate and identify one particular gene in a genome
- end=this +end =this longer fragments, shorter fragments
4 ingredients to produce tagged dna fragments to be used to read a dna sequence small, single stranded dna pieces, enzyme that makes a complementary strand, 4 nucleotide bases, and flouresent die
The pattern of the colored bands on a gel tells the exact sequence of the bases in DNA
Recombinant DNA produced by combining dna from different sources
Polymerase chain reaction technique that allows biologists to make many copies of a certain gene

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.
