<p>Yeah, that tree one I left blank too. It was something where it listed 4 types of trees, and I just thought, "screw THAT!" and left it blank. hahahaha I'd be happy with a 400, considering how much of that test I left blank. </p>

<p>None of the choices for the one about the colorblind kid (I think it was labeled person #6) or rather why he WASN'T colorblind. None of the choices seemed to fit. Colorblindness SOMETIMES skips a generation (I think that's the one I picked because the others were just waaaaaaaay too far off), but not always, so I wouldn't necessarily associate that with the gene...</p>

22

<p>what about the polymerase question? and whats a Bristle?</p>

23

<p>for polymerase i put amplify q of DNA</p>

<p>according to wiki a bristle is a thin hair</p>

24

<p>i tried guessing but now i thnk i shoulve just left it blank</p>

25

<p>did anyone put the bristle thingy as an answer or did u just put hair ( was it in the choices) ?</p>

26

<p>I picked that it split the DNA strand at different locations... I remember hearing something about DNA polymerase, and I associated it with splitting the DNA for recombination. However, I usually would associate a word sounding like "polymerase" with putting something TOGETHER, which was also a choice, soo..... I might have made the wrong choice. lmao Oh well!</p>

27

<p>hair was a choice for one, and i put it for number 3 or something or 4</p>

28

<p>Yeah... well... it went ok... i think. There was one I left blank and 8 I was not 100% sure on. But I looked over some of the ones that were ify and I think they seem OK. Hopefully. Then factor in one or two mistakes other mistakes....</p>

29

<p>helicase im pretty sure splits in the replication fork, i remember hearing DNA polymerase is the key enzyme in DNA replication a lot of times... who knows? I hate CB</p>

<p>you know for the plant experiment, it said like which of these nutrients is the most limiting, which did you guys put? I put carbon</p>

30

<p>do u guys remember the q about chromosome mutation which of the choices wasnt responsible for it ?? was it translocation <em>fingers crossed</em>
and what about the genome ques??</p>

31

<p>i put nitrogen / phosphate ^-^</p>

32

<p>The genome question was coding for proteins, definitively. :)</p>

33

<p>i put translocation. and DNA polymerase i put the one about putting togther. also..the plant experiment i left blank, iwasnt sure at all</p>

34

<p>For which one of these is NOT a chromosomal mutation im like 90% sure its synapsis (because it is the pairing of homologous chromosomes during meiosis)</p>

<p>Wait, why would the plant one be nitrogen or phosphate? they were each separate answers first of all, and secondly the growth increased</p>

<p>SillBill, can you remind me what the genome question was like, so I can thank god I did not make a dumb mistake</p>

35

<p>but what if something goes wrong in synapsis mutation occurs and isnt translocation transport of food in a plant ??
this test is really makin me nervous i hope the curve is good ! :(</p>

36

<p>Translocation is definitely a chromosomal mutation. I don't want to sound almost sure it was synapsis </p>

<p>I think you are thinking of transpiration which is evaporation of water from plants</p>

37

<p>............</p>

38

<p>Reciprocal Translocation is a chromosomal mutation they only said translocation ! :(</p>

39

<p>Chromosomal</a> translocation - Wikipedia, the free encyclopedia</p>

<p>wat was the answer to the genome question..i put 30,000 proteins or sumthing.. i dont remeber. also i put synapsis..i was thinking synapsis was the transmitter of signals thing so it cant be a mutation. and i know transloaction is def. a mutation. i have it one of my prep books. did the circulatory sytem question seem hard. i didnt knwo wat animal it was like..i put a bird.</p>
