Dongqi mosquito virus news, what virus about mosquitoes this year?

It's all over the country and it's okay to pay attention to cleanliness.

The news reports these days are Zika virus, a virus transmitted through mosquito bites.

(1) The recipient cells commonly used in animal genetic engineering are fertilized eggs, and each somatic cell of the individual into which it develops contains the target gene; The gene of interest needs to be transcribed and translated normally in the receptor to control the emergence of the corresponding trait

2) "Only the embryos of gene A or gene B are lethal" means that the embryos of ABB and AAB are lethal, so the male and AAB mosquitoes intersect, and the genotypes of the offspring are all ABB, no lethality, and the gene frequency of A is 50%; a b in f2 : a bb : aab:

The AABB should be 9:3:3:

1. Due to the lethality of the embryos of ABB and AAB, 3 should be eliminated

16 a bb, 3

16 AAB, so for A, A, 1 will be eliminated

16 of aa, 1

8 of aa, 3

16, so aa:aa:aa=3:6:1 in f2, so the gene frequency of a is 60%.

3) The frequency of S gene in the population increased from generation to generation, and the protein expressed by S gene could inhibit the proliferation of viruses in mosquitoes, so that the average number of viruses in mosquitoes decreased from generation to generation

Therefore, the answer is: 1) the zygote S gene, the mRNA S protein transcribed by the S gene.

3) S protein that reduces S gene expression inhibits dengue virus replication

Common types of bacteria: malaria, dengue, plague (Black Death), yellow fever, West Nile virus, white fever (sandfly fever), ......

Common parasite species: Plasmodium, filaria (filariasis, rubber leg disease), trypanosomes (trypanosomiasis), horse fly eggs, ......

Everything!! Biting AIDS and then biting SARS!! There are also new viruses that mix

Many popular science emphasizes that some viruses cannot survive in mosquitoes for a long time, and mosquitoes do not continuously suck blood.

However, it can be passed on to bats or small animals, and bats do not wait for mosquitoes.

There is also the problem that the virus cannot survive in mosquitoes and cannot be carried by mosquitoes are two natures.

The mosquito sucks the virus-containing A, and the mosquito rests and the virus gradually dies. However, the mosquito did not successfully suck blood A, and was disturbed without eating enough, so the mosquito chose B, so the infection between AB became possible.

Being bitten by a mosquito is not just a pimple, more than 80 diseases such as malaria and dengue fever are transmitted by mosquitoes.

You can use mosquito lamps, or apply some wind oil essence, which can relieve itching.

Are you afraid of infectious diseases?

The premise is that the mosquito that bites you carries infectious disease germs, that is, that the mosquito has bitten a patient with an infectious disease.

The probability of you getting sick is not high, so there is no need to panic.

Mosquito killing, mosquito coil, mosquito repellent spray, Liushen flower water.

With a mosquito killer lamp, I used Jili's is not bad, I recommend you to use it.
