谁生物学的好啊,进~帮我个忙..

[芭蕾娃娃℃]

不包括,但是基本知识里要知道吧
我们主要考6章...其中有一章是关于GENETICS的,不太难
难的在TUMOR和什么ONCOGENES,还有原因啊之类的,还有分裂速度之类的,哭了

Eukaryotic Cell Division:
Eukaryotes can divide by mitosis and meiosis. Mitosis is simple cell multiplication, no genetic variations involved. Meiosis can make four genetically different haploid celles.
The main stages for meiosis and mitosis are the same: Inter Phase (G1, S, G2 stages)and Mitosis/Meiosis stage. In the mitosis/meiosis stage, there are prophase, metaphase, anaphase and telophase.
Meiosis occurs in two steps: meiosis I and meiosis II. The meiosis I can separate the two homologues chromosomes and the meiosis II can spearate the sister chromatides.
Prophase: neucleus breaks down, chromosomes freed
Metaphase: chromosomes (chromatids for mitosis) lined in the middle
Anaphase: chromosomes (chromatids for mitosis) separated by the spindles
Telophase: neucleus reforming

Cytokenesis occur after， to separate the two celles. Animal cells use cleavage; plant celles forme new cell wall using substances delivered by Golgi.

我和你学的不是一本书.
btw, TUMOR和什么ONCOGENES我不学……

 

[芭蕾娃娃℃]

你这个我上个月FIRST MIDTERM时候考完了...
呵呵，为了这个快忘光了的破生物,我特地叫偶老妈从北京弄了几本生物书给我...
结果收到以后发现我妈弄错了,给我找的都是选修的..

 

[SpetsNaz]

lol, 你在哪里学生物呢？

 

[芭蕾娃娃℃]

我MAJOR不是生物..
选修的..结果发现好难..
我在U OF CALGARY

 

[Biochemistry]

U OF CALGARY不错。为什么不去U OF ALBERTA？

 

[芭蕾娃娃℃]

我学的商科，卡大的比ＵＡ好

 

[Biochemistry]

那倒是。你认识CHRIS吗？他是中加的外教，是U OF CALGARY毕业的。

 

[SpetsNaz]

选修课选择生物？ lol.....

 

[芭蕾娃娃℃]

我见过,一个个子高高的,听说特可爱
选修有人骗偶说生物简单,就2次期中一次期末,不用交作业，没有QUIZ,结果上当了..

 

[SpetsNaz]

哈哈，惨啊
