The question is incomplete as the options are not provided which are:
RNA replicase is present in the viral capsid.
The RNA genome is of the plus sense and RNA replicase is present in the viral capsid.
The new bacteriophage is a retrovirus.
The RNA genome is of the plus sense.
Answer:
The RNA genome is of the plus sense and RNA replicase is present in the viral capsid.
Explanation:
The bacteriophage is the virus particles which are composed of the genetic material enclosed in the Capsid protein. The Bacteriophage virus infects the bacteria and uses their replication machinery to replicate themselves.
In the given question, all the proteins along with RNA for translation or ribosomes is provided. The single-stranded RNA is first their genome copied by the RNA replicase and the positive strand, therefore, acts as the mRNA. This mRNA is then translated into the protein sequence and a new virion is produced.
Thus, the selected option is correct.
Answer:
Option A. amphipathic molecules
Explanation:
Amphipathic molecules have both polar and non-polar parts which means they contain hydrophilic and hydrophobic regions in their structure.
These molecules are found in lipids. More specifically, phospholipids are considered as the fundamental building block of the cell membrane. They are arranged in a bi-layer having a hydrophilic head and hydrophobic tails to maintain the fluidity of the membrane.
Proteins that tag pathogens for destruction by immune cells are called (D) Interferons. Interferons are group of proteins used for signals. It is produced whenever there is a pathogen (whether a virus, bacteria, parasites or tumor cells) present in the body. It causes its neighbor cells to increase their anti-viral defense.
