<span>In order to happen DNA synthesis of a wanted portion of DNA in laboratory, the DNA polymerases that preform that synthesis need to have a an existing strand of nucleotides already in order to attach new DNA nucleotides. To that existing strand of nucleotides we call primer. In a lab, scientists synthesize DNA primers through specific sequences that bind to other sequences of a single-thread DNA molecule and these are the primers commonly used to perform PCR.</span>

madreJ [45]

Answer:

Since all forms of bacteria are prokaryotic and in turn unicellular their offspring don’t have to undergo a long period of gestation and growth prior to relative maturity. Whereas any organism (for the most part) in the animila kingdom do and any animal also require a mate. So one major benefit of bacteria being capable of asexual reproduction is they don’t require a mate to reproduce hence the name ASEXUAL. Also, another benefit I vaguely/briefly mentioned is the ability to reproduce at a faster rate than many if not all eukaryotic organisms. For example E.coli a type of bacteria can reproduce in as little as 20 minutes if I recall correctly.

Answer:

If the Earth weren't tilted on its axis, there would be no seasons. And humanity would suffer. When a Mars-size object collided with Earth 4.5 billion years ago, it knocked off a chunk that would become the moon. It also tilted Earth sideways a bit, so that our planet now orbits the sun on a slant.
