Answer:
The lytic cycle has 6 stages: Attachment, penetration, transcription, synthesis, maturation, and lysis.
Explanation:
- Attachment: is the first step of the lytic cycle, and it consists of the attachment of the virus to the host cell, which is the cell that the virus will infect.
- Penetration: once that the virus is attached to the host cell, this penetrates the cell's membrane to introduce its DNA. When the virus DNA is inside the cell's DNA is destroyed.
- Transcription: now the virus has all the machinery to reproduce itself. In other words, the cell starts the transcription of the virus's DNA.
- Synthesis: the cell synthesizes the virus' DNA and proteins.
- Maturation: in this process, the new virus is assembled and ready to be outside the cell.
- Lysis: as the viruses are ready to infect other cells, they go out of the host cell by lysis, which is a process where the membrane is broken and the cell dies to free what is inside.
The vertebral column, when seen from the side, has 4 curves: 2 convex curves (cervical and lumbar curves) and 2 concave (thoracic and sacral curves). This curves are the feature of the skeleton that allow a child to maintain balance in the upright position eventually.
When we are born we have a single concave curve throughout the whole vertebral column but, as we grow, still in the early months as we try to hold our head, the cervical curve starts to develop, and later, as we try to sit up, stand up, and walk, the lumbar curve aslo starts to develop. In few years we have all curves fully developed.
