Biology

kolezko [41]3 years ago

Answer:

DNA replication a process of copying of a cell's DNA.  DNA replication is semiconservative process which means that each strand in the double helix helps in the synthesis of new, complementary strand and conserve the parent template.

The Molecular mechanism of DNA replication is as following:

  1. The double starnded DN in binded with hydrogen bond, the enzyme helicase opens up the DNA at the replication fork.
  2. A single stranded binding protein prevent the rewinding of DNA and so binds to the DNA around the replication fork
  3. Topoisomerase prevent supercoiling at replication fork.
  4. The ezymes primase come in action and produces RNA primers which are complementary to the DNA strand.
  5. DNA polymerase III help to extends the primers and allow them to add  to the 3' end, to make new DNA.
  6. DNA Polymerase then remove RNA primers and replace with DNA.
  7. DNA ligase blocks the the gaps between DNA fragments.

So, this is the molecuar mechanism of DNA replication.

Which two features indicate that a cell is a plant cell and not an animal cell? A. cell membrane, flagella B. lysosome, vacuole
Triss [41]
c. cell wall, vacuole

Among the choices above, the two features that indicate that a cell is a plant cell is the cell wall and vacuole. The cell wall can only be found in plant cells. It is the rigid cell that surrounds the cell membrane. The vacuole of a plant cell and animal cell are way too different. The vacuole of an animal cell is usually more than one and small, even smaller that that of the plant cell. On the other hand, the vacuole of the plant cell is only one in fact a large one that takes up almost 90 percent of the volume of the cell

Why can you not prove a hypothesis
ss7ja [257]

Answer:

To conclude, you cannot prove a hypothesis because you can never generalise the results to the whole population and foresee the results will always be the same in the future. You can however, reject the null hypothesis consistently, through statistical hypothesis testing so that the theory becomes highly likely to be true, but not proven.

The embryonic stem in a seed is the plumule.

it grows out of the hypocotyl, which that itself grows out of the radical, which is attached to the microphyl, feeds on the cotyledon, is fertilized by the endosperm, and is all protected by a hard seed coat :)
