Answer:
How cloning works: In reproductive cloning, researchers remove a mature somatic cell, such as a skin cell, from an animal that they wish to copy. They then transfer the DNA of the donor animal's somatic cell into an egg cell, or oocyte, that has had its own DNA-containing nucleus removed. ... This young animal is referred to as a clone.
Basics of cloning:
Isolation of target DNA fragments (often referred to as inserts)
Ligation of inserts into an appropriate cloning vector, creating recombinant molecules (e.g., plasmids)
Transformation of recombinant plasmids into bacteria or other suitable host for propagation.
Screening/selection of hosts containing the intended recombinant plasmid .
Explanation:
"Viruses straddle the definition of life. They lie somewhere between supra molecular complexes and very simple biological entities. Viruses contain some of the structures and exhibit some of the activities that are common to organic life, but they are missing many of the others. In general, viruses are entirely composed of a single strand of genetic information encased within a protein capsule. Viruses lack most of the internal structure and machinery which characterize 'life', including the biosynthetic machinery that is necessary for reproduction. In order for a virus to replicate it must infect a suitable host cell".

Answer: the mass would be 3
<u>Answer:</u>
<em>The measurement 100.5 mL has 4 significant figures.</em>
<u>Explanation:</u>
Significant figures are defined as the digits that provides information in order to maintain accuracy and precision of a measurement. <em>Any nonzero number, trailing zeros with a decimal point and zeros between two numbers are recognizes as significant digits. </em>
Whereas, the figures which do not contribute to sustain the accuracy and precision of the measurement are insignificant figures.
<em>The leading zeros in any digit and the trailing zeros without decimal are considered as insignificant figures. </em>
<em>As in 100.5 1, two zeros and 5 after a decimal is significant figure which are 4 in total.</em>
Answer:
Scientist obtain the primers from the DNA polymerases that preform the synthesis which must have an existing strand of nucleotides already in order to attach new DNA nucleotides. The existing strand of new DNA nucleotides is the primers
Explanation:
In order to happen DNA synthesis of a wanted portion of DNA in laboratory,
Scientist obtain the primers from the DNA polymerases that preform the synthesis which must have an existing strand of nucleotides already in order to attach new DNA nucleotides. The existing strand of new DNA nucleotides is the primer. To that existing strand of nucleotides we call primer. In a lab, scientists produce 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.
