Answer:
During DNA replication, the leading strand is synthesized in the 5' to 3' direction. The strand that runs away from the replication fork is synthesized in Fragments because DNA polymerase cannot synthesize in the 3’ to 5’ direction.
Explanation:
- A replication fork has one strand called the leading strand, it is synthesized continuously from a single primer on the leading strand template and grows in 5'-3' direction.
- The leading strand grows in the same direction in which the replication fork grows.
- The other strand is the lagging strand that is unveiled by the growing replication fork. It proceeds in the direction opposite to the movement of growing replication fork.
- The lagging strand is synthesized discontinuously because the DNA polymerase can add nucleotides only to the 3' end of a primer.
- These short pieces of synthesized DNA are okazaki fragments.Okazaki fragments are joined later by ligase.
Answer:
they might be spliting(reproduction) to make offspring
Explanation:
Answer:
Skeletal system provide strength and protection to heart and also produces essential blood cells such as RBC and WBC
Explanation:
All organ systems in our body work in co-ordination with each other. Skeletal system comprised of bones and cartilages while cardiovascular system comprises of hearts, blood and blood vessels. Firstly the skeletal system protects the heart and also assists in its pumping along with muscle. Secondly, the blood cells such as RBC and WBC are circulated by the blood throughout the body. However these cells are produced in the bone marrow (inside the bones)
Answer:
<em>The correct option is d) distal humerus fracture</em>
Explanation:
The humerus is one of the three bones which join to make up the elbow joint. A break in the lower end part of the upper elbow results in distal humerus fracture. Such types of events are caused due to high energy collisions such as during an accident. The distal humerus fracture can be treated through a surgery. During the surgery, the normal motion of the humerus is tried to be restored.
Answer;
Tuberculosis
Explanation;
Bloodborne transmission involves transmission through contact with infected human blood and other body fluids such as semen, viginal secretions etc.
These pathogens include; HBV, HIV, STD's and viral hemorrhagic fevers.
Tuberculosis (TB) is not transmitted through the blooborne method but through airborne particles.
