How does an enveloped virus gain/obtain/get its envelope?

Biology
1 answer:
Arte-miy333 [17]4 years ago

Answer:

The envelope come from the host cell membrane as the virus leaves the host cell

Explanation:

A virus is an organism that is incapable of replicating on its own without infecting a living host. A virus consists of a genetic material (DNA or RNA) , a protein coat called CAPSID, and sometimes some viruses possess an envelope, which is an outer covering or enclosure. Viruses that possess this envelope are referred to as ENVELOPED VIRUS.

The virus lacks the ability to produce any structure, hence, they gain this envelope made of phospholipid from the cell membrane of the host they infect. During the infection cycle of a virus, a process called budding enables a portion of the host's plasma membrane to cover or encapsulate the virion cells, hence, making them enveloped in the process.

HACTEHA [7]

Answer:

Framshift mutation

Explanation:

The frame shift mutation is also known as reading frame shift or framing error mutation, during which an insertion or deletion occurs at a single position but it effects the sequence of whole gene in such a way that complete sequence is disturbed.

If we look at the sequence given in example:

Wild sequence: the big red fly had one eye

Mutant:               the fbi gre dfl yha don eey

An insertion mutation occured at the start of sequence big, where f got inserted. We know that a 3 set of nucleotides called codon is transcribed and translated into single amino acid of protein. So when f got added it disturbed the frame and all the sequences of next codons got altered.

  • big  changed to fbi
  • red changed to gre
  • fly changed to dfl
  • had changed to yha

In short the ehole protein will have wrong sequence of amino acid and it is worst type of mutation that badly effects an organism.

Hope it help!

Drag each label to the correct location on the image.<br> Identify these elements of photosynthesis.
wariber [46]

Answer:

  • Light energy is near the sunrays.
  • carbon dioxide is given by the plant respiration that is leaf.
  • Glucose is stored inside the tissues or the body of the plant.

Explanation:

  • The plant performs a chemical activity of photosynthesis under the light during the daytime. During this process, the visible part of the spectrum reflects back the other spectrum of light.
  • The plants produce oxygen and take in carbon at the same time they also provide carbon dioxide. Glucose is a type of energy available in starch is stored in plant leaf carbon dioxide is used to convert into sugar to form glucose.

Phosphorus cycle takes place even without human involvement but it can still affect or cause major changes in this nutrient cycle. </span>Humans use fertilizers and raise livestock (hogs). Waste from livestock and fertilizers are high in phosphate that gets into the soil and bodies of water through drainage and run-off.
