Answer:
kyphosis.
Explanation:
Kyphosis, also known as roundback or hunchback, is a condition in which the spine in the upper back has an excessive curvature.
The upper back, or thoracic region of the spine, has a natural slight curve. The spine naturally curves in the neck, upper back, and lower back to help absorb shock and support the weight of the head. Kyphosis occurs when this natural arch is larger than normal.
In addition, people with kyphosis appear to be slouching and have noticeable rounding of the shoulders. Kyphosis can lead to excess pressure on the spine, causing pain. It may also lead to breathing difficulties due to pressure put on the lungs.
Answer:
To reproduction
A process which Two parent cells
union to produce four daughter cells
Answer: The enzyme being targeted by this type of drug is DNA topoisomerase or DNA gyrase.
Explanation: Replication requires not just a single DNA polymerase but different enzymes and proteins, each performing a specific task. DNA helicase separates the two parental DNA strands that act as templates in replication by moving along the DNA and separating the strand using chemical energy from ATP. DNA topoisomerase or DNA gyrase relieves the torsional strain or topological stress generated by DNA unwinding. DNA-binding proteins binds and stabilizes the separated single-stranded DNA. Primase synthesizes the short segments of RNA (RNA primers) which must be present on the template before DNA polymerase can begin to synthesize DNA.
