In 1918, an influenza pandemic that originated with avian flu killed 50 million people. Researchers isolated samples of that vir

us from bodies of infected people preserved in Alaskan permafrost since 1918. From the samples, they sequenced the viral genome, then reconstructed the virus. The reconstructed virus is 39,000 times more infectious than modern influenza strains, and 100 percent lethal in mice. Understanding how this virus works can help us defend ourselves against other strains that may arise. For example, discovering what makes it so infectious and deadly would help us design more effective vaccines. Critics of the research are concerned: If the virus escapes the containment facilities (even though it has not done so yet), it might cause another pandemic. Worse, the published DNA sequence and methods to make the virus could be used for criminal purposes. Do you think this research makes us more or less safe?

Answer:

Personally, I believe the information helps.

Explanation:

Without this information the virus would not be contained, we would not have done research, taken samples, tested out the virus, or even attempted to contain it. With this information we can attempt to prevent a break out of the disease again. This is my personal opinion though.

DELETION OF SNORD116, A PRADER-WILLI SYNDROME CANDIDATE GENE, DOES NOT AFFECT CIRCADIAN RHYTHMS IN MICE MODELS
Vlada [557]

Prader-Willi syndrome (PWS) is a gentic disorder which has an impact on numerous physiological systems. PWS affected individuals (specifically babies) experience delayed growth, significant hypotonia (low muscle tone), and feeding issues. It does effect circadian rhythms in mice models.

SNORD116, often referred to as HBII-85, is a non-coding RNA (ncRNA) molecule that contributes to the alteration of other small nuclear RNAs (snRNAs). Unlike the majority of other snoRNAs, SNORD116 is not significantly complementary to ribosomal RNA and is expressed widely in the brain (but not in PWS patients).

According to the studies, SNORD116 cause sleep defect in patients with Prader-Willi syndrome. Same observation was seen in mouse models too. Paternal expression of SNORD116 is thought to be a potential gene for the sleep disruptions/circadian rhythm’s that the majority of PWS sufferers.

When the food is going on fermentation, there are good bacteria over there that will inhibit other bacteria to grow on that food. Fermentation also able to made the pH more acid, making the area is not suitable for bacterial growth.

Plant viruses spread throughout the plant by way of __________. View Available Hint(s)for Part A chloroplasts plasmodesmata vert
KatRina [158]

Answer:

Plasmodesmata

Explanation:

Plasmodesmata are microscopic channels which traverse the cell walls of plant cells and some algal cells, enabling transport and communication between them. This is the path that viruses use to spread throughout a plant's system.

Hope this helped! :^)
