The earth orbits the sun. Due to this fact, the northern and the southern hemisphere are tipped toward the sun at different times. Different climate zones fall under the southern and the northern hemisphere. There are many factors which affect the climate of a place and the most important one out of these factors is LATITUDE. Latitude refers to how far or close an area is to the north or the south of the equator. The latitude of a place determines the length and the intensity of sunlight that that place will experience. Thus, a place that is closer to the equator will continuously receive a lot of direct sunlight and such a place will have a warm climate.
Muscle and nerve cells both contain the complete genome of the organism contained within their DNA. This means that both cells will contain all the same genes including the gene coding for the protein required in the sodium potassium pump. (Note the difference between cellular types and functions is the EXPRESSION of genes is different; all cells share the same genes but do not necessarily express them).
If both cells require the sodium/potassium pump and associated proteins than it is likely the exact same gene. Proteins are created through expression of genes. First the gene (a discrete section of DNA on a chromosome) is transcribed into an RNA message in the nucleus (RNA is similar to DNA and contains just the gene itself. Think of it as a post it note that has been copied from an encyclopedia of genes. Then the RNA is translated into a protein, which is a long chain of amino acids. The particular order and properties of the constituent amino acids that make up the protein cause it to coil up and form a 3 dimensional structure with properties that govern its particular function in the cell. In this case, the protein plays a key role in the sodium potassium pump. Protein synthesis is a fascinating topic and for more information, study up on the central dogma of genetics.
Answer:
The structure your are referring to is showing the virus's genome.
Explanation:
Viruses can be described as a tiny agent which multiplies inside a host cell and is usually harmful for the host cell.
The genome of a virus might be in the form of DNA or RNA. In the figure you might be referring to, there are two strands of genome present so we can say that the virus has DNA as genome. All life of life forms, from bacteria to animals and plants can be infected by viruses.
