|
Answer» Thank you Yogita..? Viruses :\tThey have a protein coat.\tThe genetic material may be either DNA or RNA.\tThey can infect plants, animals and bacteria.Viroids :\tThey do not have a protein coat.\tThe genetic material is RNA.\tThey can infect only plants. Viruses\xa0(Virus\xa0particles or virions) are usually units consisting of nucleic acids and coat proteins called capsids.\xa0Viroids\xa0consist only of RNA, i.e. they contain no protein at all. |
