Nope they donot instead they have plasmids and chromosomal
Answer:
The bacterial DNA gets degraded at step 3 of the viral lytic cycle.
Explanation:
Viruses are organisms that are incapable of replicating on their own, hence, they require a living host which they infect and use its replicational ability to reproduce theirselves. The infection cycle of this virus is regarded as its replication cycle. Viruses employ either the LYTIC or LYSOGENIC cycle for infection.
The lytic cycle involves killing of their host cell at the end of the cycle. Generally, the cycle starts with the attachment of my the virus to the cell membrane of its host using specific receptor sites (step 1). It then penetrates the host cell as seen in step 2.
After penetration, the virus then secretes certain degrading enzymes called ENDONUCLEASES that degrades the bacterial DNA. After which the virus uses the replicational and gene expressing ability of the host to transcibe its genetic material and replicate itself. This process called SYNTHESIS occurs in step 3.
Hence, the yellow ring in the image that represents bacterial DNA disappears in step 3 (synthesis stage) because it gets degraded by viral digesting enzymes.
Answer:
Respiration
Explanation:
cross off Photosynthesis because that is specifically for plants. Diffusion is when molecules move from high concentration to low concentrations. Osmosis helps transport water across the cell.
By process of reduction you can figure it out, but here is what cellular respiration is in it's basics so you can remember in the future. Cellular Respiration is just the process that takes place in cells to convert Chemical Energy from nutrients and turn it into ATP, then releases waste.
Explanation:
B is the right answer because none to the others sound like a real solution
Answer:
oot systems are mainly of two types (Figure 1). ... Dandelions are a good example; their tap roots usually break off when trying to ... The outermost cell layer of the root's vascular tissue is the pericycle, an area that can give rise to lateral roots
