Answer:
This experiment proved that DNA replicated semiconservatively; half the original polynucleotide is conserved in each of the two copies
Explanation:
Semi-conservative mode of replication means that the two strands of DNA unwind from each other, and each of themacts as a template for synthesis of a new, complementary strand. As a result, two formed DNA moleculesc ontain one original strand and one new strand.
Meselson and Stahl experiment showed this model by labeling the DNA of bacteria across generations using isotopes of nitrogen ( patterns of DNA labeling showed the mode of replication).
Answer is: <span>nondisjunction.
</span>Nondisjunction<span> is the failure of </span>homologous chromosomes<span> to separate correctly during </span>cell division, because of tha daughter cells have abnormal chromosome numbers. This example is <span>failure of a pair of </span>homologous chromosomes<span> to separate in </span><span>meiosis I.</span>
Answer:
1) Organisms in this level are either unicellular or colonial (Cellular level).
2) Organisms that live in a group called a colony (Colonial).
3) The work being divided up into specialized tasks (Division of labor).
4) A very long, contracting cell (Fiber).
5) A group of tissues working together as a unit (Organ).
6) A degree of organism complexity. Organisms at this level have their cells arranged into organs (Organ level).
7) The highest level of complexity of a living thing (Organism level).
8) The limiting of the function of a cell to a specific function muscle (Specialization).
9) A group of organs working together for a common purpose (System).
10) Organisms at this level have their cells arranged into systems (System level).
11) Cells working together to perform a particular task division of labor (Tissue).
12) Organisms at this level have their cells arranged into tissues (Tissue level).
A eukaryotic cell has far more organelles and most prominently, has a nucleus. A prokaryotic cell stores it's DNA in it's cytoplasm.
Answer:
If that is a picture of DNA, then nucleic acids are the most common macromolecule
