In Eukaryotes, the DNA replication can start at several sites or places in the DNA molecule or DNA strand. The only important factor for DNA replication to start is that it starts at replication fork.
The replication of DNA is semi-conservative in nature because each strand acts as a template for synthesizing a new complementary strand of the double helix.
The new DNA is made with the help of the enzyme DNA polymerase which requires a primer for starting the DNA synthesis.
Replication occurs only at specific regions of DNA known as origin of replication and these are short sequences of nucleotides which are recognized by the enzyme for the replication.
The special enzymes or proteins recognize the specific sites and then binds to them. After binding, the DNA is opened up forming the replication forks which are two Y- shaped structures.
Answer:
<u><em>Hawk </em></u>
Explanation:
Biomagnification can be described as the accumulation of substances like toxins, pesticides etc in tolerant organisms. The biomagnification tends to increase as the trophic levels of a food chain increase. This is because these substances get more and more accumulated as they move up a food chain.
In the example of the food chain mentioned in this question, the highest trophic level is of hawks, so they will be subjected to the greatest biomagnification.
Answer:
No
Explanation:
Carbohydrates are a source of energy for the body to use. DNA is your genetic code, it can't be altered unless through sexually reproduction. Genes are your physical attributes that are gained through the combination of your parents DNA
Answer:
C - Ammonia
Explanation:
Ammonia is a highly toxic compound that is detrimental to one’s body. This toxic compound is often, and must be transformed into urea (uric acid) before being excreted from the body.
Answer:
3, Matter cannot be created or destroyed, only transformed
