Answer:
inactive proteins can be activated by phosphorylation
Explanation:
Proteins are regulated after translation by the non-covalent binding of small molecules. These molecules include amino acids or nucleotides. A change in the conformation and thus, the activity of the protein is usually achieved when this occurs.
Proteins could also be regulated by phosphorylation which is the addition of phosphate groups of specific amino acids on the protein.
Answer:
The option 'All cells contain a nucleus' is not a part of the cell theory.
Explanation:
The cell theory proposed by scientists illustrates that every organism whether prokaryotic or eukaryotic is made up of a cell or different kinds of cells. It also that explains that cells are made from living things. According to the cell theory, cells are termed as the basic unit of life, without which life is not possible.
The cell theory does not claim that every cell must have a nucleus because many cells like cells of prokaryotes lack nucleus. Their genetic material is dispersed in the cytoplasm.
Answer:
The Markonikov's rule determines where to add a nucleotide in the reaction
Explanation:
In organic chemistry, the organic carbonyl reactions are governed by a set of rules. One of them is the Markovnikov's rule. Basically, the rule determines where the addition of the nucleophile and a hydrogen will take place in a chemical reaction involving alkene addition. In the reaction principles, there are rules to follow based on the syn and anti addition. This refers to which side the two groups will face. they add to the same side an called the syn. When its opposite side, then its anti.
