Genetics Exam II (3)

HU: Frankel

QuestionAnswer (1)Answer (2)
translation taking nucleic acids and translating them to amino acids N/A
6 things needed for initiation 1) mRNA 2) ribosomes 3) initiator tRNA 4) initiation factors (IF-1, IF-2, IF-3) 5) magnesium ions 6)GTP N/A
"E-site" exit site where tRNA's are released
"A-site" aminoacyl binding site where next tRNA will attach
4 things needed for elongation 1) charged tRNAs 2) elongation factors(EF-Tu, EF-Ts, EF-G) 3) GTPs 4) peptidyl transferase N/A
What does GTP do in elongation? gives the energy required to transfer the charged tRNA N/A
2 things needed in termination 1) release factors (RF-1, RF-2, RF-3) 2) GTP N/A
What codons do RF-1 recognize? UAG or UAA N/A
What codons do RF-2 recognize? UGA or UAA N/A
aminoacyl-tRNA synthetase required for activation of amino acids N/A
EF-G catalyzes translocation N/A
EF-Tu & GTP places tRNA in the "A site" N/A
post-transcription occurs where? eukaryotes in the nucleus
translocation messenger moves down the ribosome (shifts one codon) N/A
peptidyl transferase catalyzing peptide bond N/A
Suedberg units sedimentation coefficients big#- big molecules small#- small molecules
30s divides into 23s, 16s, 5s (in prokaryotes) not additive
spacial DNA eukaryotic rRNA has this due to exons (not transcribed) N/A
45s divides into 28s, 18s, 5.8s (in eukaryotes) 5s comes off of different gene sequence
"P-site" peptidyl binding site where tRNA's anticodons attach to the codons of the mRNA

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.
