<u>Answer:</u>
The correct answer is Uracil which is nitrogen base found in RNA.
<u>Explanation:</u>
Uracil is a nitrogenous base which is located within an RNA molecule but not within a DNA molecule.
Uracil, represented by the letters A, G, C and U, is one of the four nucleobases that are found in the nucleic acid of RNA which binds to adenine.
While thymine is present in the DNA and binds to adenine.
The allele that is masked is recessive. The one which masks it is dominant.
Gravity Probe B showed this to be correct, in 1905 Einstein determined that all laws of physics are the same for all non accelerating observers <span />
Answer:
The correct answer is: E) both B and C.
Explanation:
- Bacteria and Archaea forms two distinct and different Domains in the Taxonomic classification system.
- Nuclear envelope that surrounds and protects the genetic material by forming the Nucleus is absent in both Archaea and Bacteria. Both of them possess a region called the Nucleoid where their genetic material is located.
- Plasma membrane that surrounds the cell and maintains integrity of the cell structure is present in both Bacteria and Archaea. Although the composition of lipid in the plasma membrane is different in each.
- However, they vary in their cell wall composition. The cell wall of the bacteria is rich in a compound called peptidoglycan while the cell wall of archaea lacks peptidoglycan and is rich in polysaccharides and glycoproteins.
