True or false? the first vaccine developed was for polio. b. false 2. true or false? louis pasteur developed a rabies vaccine.

1 answer:

3 0

The smallpox vaccine, introduced by Edward Jenner in 1796, was the first successful vaccine to be developed. hence first statement is<u> False.</u>

Louis Pasteur developed a vaccine for Rabies hence, the second statement is true.

However, Pasteur's rabies vaccine represented the first effective post-exposure treatment for people bitten by rabid animals, and Jenner's smallpox vaccine resulted in the eradication of smallpox. Additionally, the polio vaccine, given since its discovery in 1950, is resulting in the eradication of polio (in the years 2004–2005). Despite the existence of a relatively powerful vaccine, efforts to completely eradicate rabies are impractical because, unlike smallpox and polio, rabies may infect both domesticated and wild mammalian species.

In the mRNA; A will be complementary to U
In tRNA; U will be complementary to A

The mutation does not affect the structure of the protein and is called a silent mutation.

<h3>What is a mutation?</h3>

A mutation is a change that occurs in the sequence of nucleotides of a gene.

The mutation that changes the base G in the DNA to A will result in the following corresponding changes in the mRNA and tRNA:

In the mRNA; A will be complementary to U
In tRNA; U will be complementary to A

The mutation does not result in any changes since the amino acid coded for by the mRNA has more than one codon coding for it.

This type of mutation is called a silent mutation.

In conclusion, some mutations occurring in genes have no effect on the proteins the gene codes for.

<h3>What is evolution of life?</h3>

A biological population's heritable traits change over successive generations, and this process is called evolution. At every level of biological organisation, evolutionary processes give rise to diversity. The last universal ancestor is a term used to describe the common ancestor of all life on Earth.

Modern living things are a direct descendant of extinct ancient life forms, according to evolution, which explains how living things are changing today. The majority of the time, living things improve their environmental suitability as they develop. Due to their ability to adapt, they do this.

We can solve biological issues that have a direct impact on our lives by comprehending evolution. In the world of medicine, there are many fantastic examples of this. Researchers need to be aware of the evolutionary trends of disease-causing organisms in order to stay one step ahead of pathogenic diseases.
