Bio 1 T4 PE

Test #4 Practice Exam

QuestionAnswer
The regions in DNA that encode actual gene products are known as: Exons
In order for an RNA primer to be synthesized on the DNA which of the following enzymes is necessary: Primase
A chemical modification that methylates DNA bases causes: inactivation and silencing of DNA
RNA processes involve addition of a methyl –G cap b. removal of introns c. polyadenylation ( adding lots of A bases to the tail)
A transcript is also known as mRNA
According to DNA base pairing rules ( Chargaff’s Rules) Example: if you have 20 % T you will have 30 % C
Use the DNA sequence below to answer questions 7-9 5’ ATGCCCGGATATACG 3’ 3’ TACGGGCCTATATGC 5’ The correct configuration of t-RNA would be: 5’ AUG CCC GGA UAU ACG 3’
Use the DNA sequence below to answer questions 7-9 5’ ATGCCCGGATATACG 3’ 3’ TACGGGCCTATATGC 5’ What amino acid sequence would be correctly constructed form reading the codons derived from this sequence? Met Pro Gly Lle Thr
What enzyme would be used to synthesize m-RNA from the DNA? RNA polymerase
Translocation is a process where the t-rna in the ________ moves in order to place the t-rna bound to the growing peptide chain in the _______ site. A, P
An m-RNA poly A- tail: protects the m-rna from degredation
The primer in DNA synthesis is composed of : RNA
If bacteria were grown on N15 labeled media first then transferred to N 14 media for three generations how many bands would be visible in the centrifuged tube at the end of the experiment? 2 Bands
List all enzymes associated with DNA synthesis and provide their functions. Helicase – unwinds dble helix Topiosomerase – prevents overwinding SSBP: stabilizes and keeps strands apart Primase: lays down rna primer DNA polymerase III – adds nucleotides to the end of 5' to 3' DNA Polymerase I: replaces RNA with new DNA DNA Li

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.
