Gene Expression

Chapter 25 Review

QuestionAnswer
Number of hydrogen bonds between Adenine and Thymine 2
Why is DNA replication considered "semi-conservative"? Each daughter DNA molecule consists of one new chain of nucleotides and one from the parent DNA molecule
During replication, the enzyme that unwinds and unzips the DNA... DNA helicase
Following replication, this enzyme seals any breaks in the sugar-phosphate backbone DNA ligase
Three classes of RNA... messenger (mRNA); transfer (tRNA); ribosomal (rRNA)
One of two promoter sequences that are used for the start of transcription TATA box (repeating TATATATATATA...) or CAAT box (repeating CAATCAATCAAT...)
the role of tRNA is to... transport amino acids to the ribosomes
These are the three steps in Translation Initiation, Elongation, and Termination
During translation, this is always the "start" codon AUG (codes for methionine)
These are the three "binding" sites on a ribosome P (peptide) site, A (amino) site, E (exit) site
If mRNA carries the codon, then the tRNA carries the...? anti-codon
Three causes of mutations: Replication Errors; Mutagens; Transposons
Type of mutations where one or more nucleotides are either inserted or deleted from DNA Frameshift Mutations

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.
