The correct option is C.
The DNA molecule is made up of four different types of nucleotide bases, these are: thymine, cytosine, guanine and adenine. The arrangement of these nucleotide bases in DNA affect the genetic traits that are eventually formed. The differences that are observed in different individuals is as a result of the different ways in which the nucleotide bases are arranged in DNA molecules.
Answer:
The Answer is Telophase
Explanation:
It is helpful to remember PMAT. P stands for Prophase which is when the DNA is replicated. M stands for Metaphase which is when the chromosomes line up in the center of the cell. A stands for Anaphase which is when the spindle fibers attach to the chromatids and pulls one to either side of the cell. T stands for Telophase which is when the cell division starts to create the two daughter cells.
All of the choices are correct.
Explanation:
Viruses are non cellular entities which are made up of either a DNA or RNA enclosed within a protein coat.
Viruses cannot reproduce by themselves. They can reproduce only within living cells and hence they are obligate intracellular parasites.
Viruses have a wide range of hosts including animals, plants, bacteria etc.
However, each viral species has a very limited host range.
