What kind of shape does a enveloped virus have?
What kind of shape does a enveloped virus have?
What kind of shape does a enveloped virus have?
Enveloped viruses consist of nucleic acid surrounded by either a helical or polyhedral core and covered by an envelope. Binal (complex) viruses have neither helical nor polyhedral forms, have irregular shapes, or have complex structures. There are no recommended articles.
How are viruses usually about the same size as bacteria?
A) Viruses are usually about the same size as bacteria. B) Viruses possess enzymes for protein synthesis and ATP generation. C) The “host range” for a virus is determined by the presence or absence of particular components on the surface of a host cell that are required for the virus to attach.
How are viruses classified on the basis of morphology?
Classification of Viruses Morphology:Viruses are grouped on the basis of size and shape, chemical composition and structure of the genome, and mode of replication. Helical morphology is seen in nucleocapsids of many filamentous and pleomorphic viruses. Helical nucleocapsids consist of a helical array of capsid proteins
What makes up the outer shell of a virus?
No matter the shape, all viruses consist of genetic material ( DNA or RNA) and have an outer protein shell, known as a capsid. There are two processes used by viruses to replicate: the lytic cycle and lysogenic cycle. Some viruses reproduce using both methods, while others only use the lytic cycle.
Enveloped viruses consist of nucleic acid surrounded by either a helical or polyhedral core and covered by an envelope. Binal (complex) viruses have neither helical nor polyhedral forms, have irregular shapes, or have complex structures. There are no recommended articles.
What kind of virus is a cylindrical helical?
The cylindrical helical virus type is associated with the tobacco mosaic virus. Envelope viruses, such as influenza and HIV come covered in a protective lipid envelope. Most animal viruses are classified as icosahedral and are nearly spherical in shape.
A) Viruses are usually about the same size as bacteria. B) Viruses possess enzymes for protein synthesis and ATP generation. C) The “host range” for a virus is determined by the presence or absence of particular components on the surface of a host cell that are required for the virus to attach.
How are viruses not part of living cells?
– Viruses are not cells, do not have nuclei or mitochondria or ribosomes or other cellular components. – Viruses replicate or multiply. Viruses do not grow. – Viruses replicate or multiply only within living cells. – Viruses are obligate intracellular parasites . – The term virus was coined by Pasteur, and is from the Latin word for poison.
