什么是基因组和基因突变?

What are genomes and gene mutations?

基因组是生物体全部遗传信息(DNA)的总和;基因突变是DNA序列发生改变,多数无害,少数可能影响功能或导致疾病。
A genome is an organism's complete genetic information (DNA); a gene mutation is a change in the DNA sequence, most harmless but some affect function or cause disease.

癌症是如何产生的?

How does cancer develop?

癌症是细胞基因突变后失控分裂、逃避死亡,并可能侵入周围组织或转移;它通常不是单一原因,而是遗传与环境多因素导致。
Cancer arises when cells acquire mutations, divide uncontrollably, evade death, and may invade or spread; it usually stems from multiple genetic and environmental factors.

为什么会有耐药性?

Why does drug resistance develop?

当微生物反复接触药物,少数发生变异而存活下来并繁殖,这些"耐药"后代让原来的药失效,就是耐药性。
When microbes meet a drug repeatedly, a few mutate and survive, breeding "resistant" descendants that the drug no longer kills, that is drug resistance.

为什么蚊虫叮咬会痒?

Why do mosquito bites itch?

蚊子叮咬时注入唾液防止血液凝固,其中的蛋白质引发免疫系统释放组胺,使皮肤发红发痒。
Mosquitoes inject saliva to stop blood clotting; its proteins trigger histamine release, making the skin red and itchy.

偏头痛和普通头痛有什么不同?

细菌和病毒有什么区别?

What is the difference between bacteria and viruses?

细菌是完整的单细胞生物,可以用抗生素杀死;病毒比细菌小得多,必须钻进细胞里复制,所以抗生素对病毒没用。
Bacteria are complete single-celled organisms killed by antibiotics; viruses are much smaller and must enter cells to multiply, so antibiotics don't work on them.
