Mutations

Learn the different types of mutations that can occur in the genome

QuestionAnswer
Changes in the nitrogen base sequence of DNA Mutation
Mutations are caused by errors during what process Replication or Transcription or Cell Division
Mutagens An agent that can cause a mutation EX: Radiation, Chemicals, or Extremely High Temperatures
What type of cells are affected by a mutation that is not inherited? Somatic Cell (body cells)
What type of cells are affected by mutation that is inherited? Gametes (egg and sperm)
Point Mutation or Substitution 1 base is changed affecting 1 amino acid
Insertion 1 base is "inserted" into DNA sequence affecting all amino acids from that point on
Shifts entire DNA sequence from mutation point to the right Insertion wtih Frameshift
Deletion 1 base is "deleted" from DNA sequence affecting all amino acids from that point on
Shifts entire DNA sequence from mutation point to the left Deletion with frameshift
THE DOG BIT THE CAR THE DOG BAT THE CAR Substitution or Point Mutation
THE DOG BIT THE CAR THE EDO GBI TTH ECA R Insertion with Frameshift
THE DOG BIT THE CAR THE DOG BIT HEC AR Deletion with Frameshift
Chemicals, Radiation, High Heat Environmental Mutagens
How many amino acids are affected? THE DOG BIT THE CAR THE DOG BAT THE CAR 1 amino acid
How many amino acids are affected? THE DOG BIT THE CAR THE EDO GBI TTH ECA R 5+
How many amino acids are affected? THE DOG BIT THE CAR THE DOG BIT HEC AR 2+
Mutations that do not get passed down onto future generations Somatic cell mutations
Are all mutations disadvantageous(detrimental)? NOT AlL! Mutations can lead to variations in organisms.
Which type of mutation is likely to cause greater genetic damage? Insertion or Deletion

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.
