Answer:
The correct option is A. It is the largest single structure created by organisms and is the largest coral reef in the world.
Explanation:
The Great Barrier Reef comprises of about two thousand and nine hundred reefs. This Great Reef covers an area of about 900 islands. The Great Barrier Reef is such huge that it can be seen from the outer space. Millions of tiny organisms which are known as corals polyps make up the Great Barrier Reef. The Great Barrier Reef is a wonder because it is the largest single structure made by humans and hence its name was suggested to be among the natural wonders of the world.
Both Mitosis and Meiosis are way of an atom slipting. Meiosis is a cell division that results in 4 daughter cells each with halo of the parents chromosomes. Mitosis is a cell division that results in2 daughter cells with the same amount of chromosomes in each one.
Answer:
The sequence of the primer for this open chain DNA replication fork is 5'ACGUUAGG3' Option D.
Explanation:
During the S phase of the mitotic division prior to cell multiplication, there is need to double the genetic make up of thr organism so as to maintain a conservation of the DNA. Replication start from the formation of primer at the replication fork of the genome, a primer is a short sequence RNA strand, which is needed to enable DNA polymerase to add DNA molecules using the parent strand. DNA replication including primer formation proceed by reading from the 3' to the 5' end, starting at a point where there is free hydroxyl group. This replication origin also start at the T and A rich region because it is easy to hydrolyse the double bounded molecules than the G and C rich.
Starting from the eight code with T, underlined, the complementary sequence that will be produced by the primase enzyme will be 5'ACGUUAGG3' which is option D, it should be noted that this sequence start from 5' and end in 3', and the sequence should not have T, since it's a RNA.
Answer:
The correct order is - 3. ribosomes 5. the endoplasmic reticulum 1. the Golgi apparatus. 4. transport vesicles. 2. the plasma membrane.
Explanation:
The protein needs to be transported from the cytoplasm to out of the cells for their target site, for example, insulin and enzymes. The protein synthesizes at the ribosome by the process of translation. It transported to the endoplasmic reticulum and move to the Golgi apparatus where it packaged and modified in the transport vesicles so it can move to, and pass through the plasma membrane.
Thus, the correct order is - 3. ribosomes 5. the endoplasmic reticulum 1. the Golgi apparatus. 4. transport vesicles. 2. the plasma membrane.
