唔好放棄Genetic ah
特別係Deduce genotype嗰啲，嚟嚟去去都係嗰個flow!
Btw 仲有兩日，大家要加油

點分 chromatids,chromosome and chromatin?

樓主上個po有答過

3. Chromatins: very tiny threads which cannot be seen when the cell is not dividing
Chromotid: one of the copies of the chromosome if the chromosome is replicated.
Chromosome: two chromatids (having two copies of DNA) join together after replication, or just one (having one copies of DNA) after sister chromatids separation

其實上個Post有位Merlot巴打另外有講：
Chromosome係睇centromere。換言之，right after DNA replication，兩個chromatids痴住同一個centromere，所以就視為一個chromosome。Sister chromatids separate之後，每個sister chromatids都有一個centromere，所以喺呢個stage，佢哋係被視為一個chromosome。

我都可以嘅，不過要晏少少先方便改。
你放上嚟比大家睇o唔ok?
比巴絲們順便學習下

最後兩日可以點 notes又溫左一次 pp又做左
重溫多次notes定點

你aim幾多先? pp做完又幾多成分?

同問
:^(

Aim 5*, DSE past paper + AL 2002-2013 +2005後CE 做晒
仲可以做乜

做到咁，咁你仲差咩先5**，點解唔aim 5**
:^(

你重溫返啲你錯左嘅題目啦
由其嗰啲明明識但唔中point嗰啲位

我個人好粗心大意，做左咁多份都係喺5-5*浮游.....
大部份錯過嘅都係嚟幾日重温左，大部份都岩得番，但essay特別弱，成日捉唔緊啲字眼，答到離曬題，除左上個post compare and contrast外，仲有咩特別字眼？

再specific啲嘅字眼你真係要refer to AL essay 逐條睇marking。

小弟一直對細胞分裂同遺傳物質唔熟
請問呢條2015 Q2c，子細胞的DNA含量
點解答案係「減數分裂時，同源染色體在赤道配對並各自分離至子細胞，有絲分裂則不會」既？

:^(

咩減數分裂唔係第一次分裂個時，子細胞係2N，第二次先係1N咩？
我答左「有絲分裂前遺傳物質複製，減數分裂前遺傳物質不會複製」
