which is not generally true of viruses?

Question

a. consist of a nucleic acid core
b. consist of a protein coat
c. have a specific host range
d. reproduce independently

Answer 1

D. Viruses can replicate themselves only by infecting a host cell. They therefore cannot reproduce on their own.

Answer 2

Sad lots of us are confusing you. I'll tell you the answer with short explanations as to why the others CANNOT be true:
a. True.Viruses do consist of a nucleic acid core which may be DNA or RNA
b. True.Viruses do have protein coats.
c. True. Each type of virus can infect only a/few specific host/s. This is called its host range.
d. False. Viruses are not living creatures and cannot reproduce on their own. They require hosts whom they infect. They utiliise the host machinery to produce copies of themselves
So, the answer is D.

Answer 3

Answer 4

Small viruses with only a few genes may be runaway stretches of nucleic acid originating from the genome of a living organism. Their genetic material could have been derived from transferable genetic elements such as plasmids or transposons, which are prone to moving around, exiting, and entering genomes.

At the most basic level, viruses consist of genetic material contained within a protective protein coat called a capsid

Viruses can replicate themselves only by infecting a host cell.Viruses with larger genomes, such as poxviruses, may have once been small cells which parasitised larger host cells. Over time, genes not required by their parasitic lifestyle would have been lost in a streamlining process known as retrograde-evolution or reverse-evolution. The bacteria Rickettsia and Chlamydia are living cells that, like viruses, can only reproduce inside host cells. They lend credence to the streamlining hypothesis, as their parasitic lifestyle is likely to have caused the loss of genes that enabled them to survive outside a host cell.

They therefore cannot reproduce on their own.

therefore viruses can not reproduce indepently coz viruses are generally not considered to be true living organisms.
so my answer is:

d. reproduce independently

Answer 5

Viruses are not considered as living things so the answer would be a.Consist of a nucleic acid core

Answer 6

its d they cant reproduce independently...they do not have thier own cytoplasm they r just made up of a dna or rna (dna 1 raids animals and rna 1s raid plants)and protein coat. they have specific host range acc. to the nucleic acid core.

Answer 7

have a specific host range

Answer 8

has a specific host range

Answer 9

D. they generally need a host to re-produce

Answer 10

D. the nasty little needy suckers need host cells to overcome and vanquish in order to thrive.
