The answer would be : <span>It is a well supported explanation which cannot become a law.
A law and a theory are different you know. In fact, the law is universel. This applies for everything unlike a theory which explains in particular why something is happening.
Any doubts ?
Hope this helps !

Answer:
The correct answer will be option-B (purine).
Explanation:
Nucleic acid structure is made up of monomer unit called nucleotide. Each nucleotide is composed of a five-carbon sugar, a phosphate group and five types of nitrogenous bases.
The nitrogenous bases are categorized in two forms the purines (adenine and guanine ) and the pyrimidines (cytosine, thymine and uracil). The "purines" contain double rings in their structure due to which they appear larger in size than pyrimidines which are made up of single rings.
Thus, Option-B is the correct answer.
Monosaccharides. mono = 1
Answer:
D - the production of a specific mRNA will increase as a result of the binding of the hormone receptor complex to the DNA
Explanation:
We are told that the hormone binds a receptor and then enters the cell, binding to the DNA and promoting transcription of a specific gene.
Transcription is the process whereby mRNA molecules are synthesised from a DNA sequence, which are then translated into specific process. D is correct, as the gene the hormone binds to will increase in transcription, producing a specific mRNA.
A, B and C are much more general processes, not linked to the actions of a hormone on a specific gene.
Answer:
miosis
Explanation:
Does crossing over occur in metosis? No, because chromosomes do not pair up (synapsis), there is no chance for crossing over. Following cytokinesis what chromosomes do the daughter cells contain? Daughter cells contain the same number and kind of chromosomes that were in the original cell.
