Answer:
The earliest known life-forms are putative fossilized microorganisms, found in hydrothermal vent precipitates, that may have lived as early as 4.28 Gya (billion years ago), relatively soon after the oceans formed 4.41 Gya, and not long after the formation of the Earth 4.54 Gya.
Explanation:
Answer:
Through a circumstance known as "secondary transfer DNA", or "Touch DNA".
Explanation:
Most times when a crime is committed, DNA samples are obtained from surfaces in the scene where the crime was committed. There is a very huge possibility of picking up the DNA of someone who was never at the scene of the crime and this is a result of a condition known as Touch DNA.
Because we touch several objects which can be moved to different locations and touch people who are also always mobile, our DNA cells can find their ways to a crime scene where we had never physically been to. This can lead to false verdicts of guilt.
Motor unit refers to the functional element of muscle contraction during an exertion. There are two basic types of motor unit: large and small motor units. During low to moderate level exercise, small motor units are activated. Small motor units are recruited during sustained activity; is made up of high proportion of type 1 muscle fibers, which are resistant to fatigue
Answer: DNA polymerase I is able to proofread; DNA polymerase III is not.
Explanation:
Escherichia coli is a gram negative anaerobic bacteria that is found in the gastrointestinal tract of and humans and animals. Escherichia coli has 5 types of DNA polymerase.
a. Polymerase I is used to repair any damaged DNA and proof reading
b. Polymerase II is used in proof reading, DNA Replication and repairs.
c. Polymerase III is primarily responsible for DNA replication. It also has the ability to proof read.
d. Polymerase IV is used to change genetic information of Escherichia coli.
e. Polymerase V is used in DNA repair in Escherchia coli.
