The correct answer for this question would be the second option. The one who invented he polymerase chain reaction (PCR) that allowed scientists to enlarge and study genetic material is Kary Mullis. PCR is <span> a technique that amplifies specific DNA sequences from very small amounts of </span>genetic material<span>. Mullis invented this while he is at Cetus. </span>
Animal cell structures and organelles interact as a system to maintain homeostasis by making sure each part of the system works together.
Sweat glands and sebaceous glands are exocrine glands. Pineal and adrenal glands are endocrine glands.
It begins with the unzipping of the double helix by
helicases. Unzipping forms y-shaped replication forks
exposing promoter regions (TATA regions) where the initiator proteins and factor bind to
the regions of DNA. A primer also
attaches to the region. DNA polymerase then
binds to the regions and begins adding DNA nucleotides
to the 3’ end of the primer based on the nucleotides on the template strand. Topoisomerase continues to unwind the DNA as the
polymerase progresses to the end of
replication.
