Why was miasma theory replaced?

Biology
1 answer:
vredina [299]3 years ago
5 0

Answer:

Miasma theory was replaced because John Snow collected data that showed that germs cause disease.

Explanation:

The theory of miasma was proposed in the past when some scientists —like doctors Thomas Sydenham and Giovanni Maria Lancisi— thought that disease was the product of emanations originated by the decomposition of organic matter. This theory was based on the fact that diseases predominated in places with poor hygienic conditions.

John Snow, an english physician, was one of the main contributors to the <u>microbial theory of disease</u>. In 1854, while a cholera epidemic was occurring, he collected data and organized it statistically and then concluded that the disease was caused by germs present in drinking water. This <u>data was contrary to the miasma theory, which would eventually be displaced by the microbial theory of the disease</u>.

What are the pros and cons of CRISPR-cas9
professor190 [17]

Answer:

It has incomparable advantages over other gene editing tools.

Explanation:

For example, the CRISPR-Cas9 system has more target sites than ZFNs and TALENs, and Cas9 has many variants that can be used in a variety of studies. Moreover, the system is extremely easy to use and can be executed in almost any laboratory.

The most important advantages of CRISPR/Cas9 over other genome editing technologies is its simplicity and efficiency. Since it can be applied directly in embryo, CRISPR/Cas9 reduces the time required to modify target genes compared to gene targeting technologies based on the use of embryonic stem (ES) cells.

Disadvantages of CRISPR technology: CRISPR-Cas9 off-target; The effect of off-target can alter the function of a gene and may result in genomic instability, hindering it prospective and application in clinical procedure.

this the best i got, hope it helps :)

Which of the chains of amino acids corresponds to the nucleotide sequence aauggcuac
maxonik [38]
The sequence AAU GGC UAC is composed of three codons each of which codes for a different amino acid. AAU codes for the amino acid called threonine. GGC codes for the amino acid called glycine UAC codes for the amino acid called tyrosine. So the chain will read  threonine-glycine-tyrosine. There are 64 possible 3 - letter combinations of DNA coding units A, C, G and T. Of these, there are three stop or non- sense codons that do not code for any amino acid, while the remaining 61 code for different amino acids.
