His discovery: DNA. His name: Friedrich Miescher. In this article, the authors try to find answers to the question why-despite the fact that virtually everyone nowadays knows DNA-hardly anyone remembers the man who discovered it. In the history of science, the discovery of DNA was a seminal...
"It was a long time in 1953 when Mendel discovered why we look the same as other people in our family. It because of small things called genes." It's in our body. In 1953, two scientists, Watson and Crick, found out that these small parts are really messages. They write in the ...
what to do.DNA is the reason that we look like our parents,because we get some of their DNA to make our own.People have been trying to understand the human body for a long time.In I860,Mr Mendel discovered why we look the same as other people in our family.It is because of small...

Why is double-stranded DNA important? Why do viruses have both RNA and DNA? Was ribonucleic acid discovered before DNA? Why do molecular biologists primarily focus on B-DNA? Why are nucleotide bases hydrophobic? Why is RNA, rather than DNA, thought to have been the first genetic material?
There may be many reasons why sex facilitates adaptation. For example, imagine two individuals in an asexual population that both have a good but different mutation. Because their DNA can't mix, their descendents end up competing with each other (this is called clonal interference) – you will...

Females were long expected to mate with only one male, especially among socially monogamous birds. With DNA technology, researchers discovered widespread female multiple mating among birds. Behavioral studies of extra-pair copulations indicated that in the majority of species, these were forced20. Acco...
So? Well, there was little or no competition for food or space. You might think of it as…um…as a…a kind of ecological vacuum. And the Notothenioids exploited fully. The species migrated into different habitats throughout the southern ocean. And its population increased dramatically, with...
