organelles are very similar to present-day bacteria, suggesting a common ancestor.
Explanation:
Some evidence suggests that some organelles like mitochondria and chloroplasts within eukaryotes were once used to be independent eukaryotes.
Endosymbiosis theory says that ancestral prokaryotic cells engulfed bacteria like cyanobacteria which with time evolved into mitochondria and chloroplast. Molecular evidence also proves that these organelles were once prokaryotic organisms because they show similar genetic makeup and ribosome type.
So these organelles are similar to present-day bacteria showing that they have a common ancestor.
<em>All are true for both DNA and RNA because they are release of ppi from the monomer provides the energy for polymerization.</em>
Proteins, lipids and complex starches (polysaccharides), nucleic acids are one of the four significant sorts of macromolecules that are fundamental for every known type of life.
The nucleic acids comprises of two significant macromolecules, Deoxyribonucleic corrosive (DNA) and ribonucleic corrosive (RNA) that convey the hereditary guidelines for the improvement,
The center structure of a nucleic corrosive monomer is the nucleoside, which comprises of a<em> sugar buildup + a nitrogenous base</em> that is joined to the <em>sugar buildup at the 1′ position.</em>
The sugar used for RNA monomers is ribose, while DNA monomers use deoxyribose that has lost the hydroxyl useful gathering at the 2′ position of ribose.
Four nitrogenous bases that are joined into the standard DNA structure. These incorporate the <em>Purines such as Adenine (An) and Guanine (G), and the Pyrimidines.Cytosine (C) and Thymine (T)</em>.
RNA utilizes indistinguishable nitrogenous bases from DNA, aside from Thymine. where is the <em>Uracil (U) found in the RNA nucleotide.</em>
The nucleotide ,When the one of phosphate group are connected to a nucleoside at the 5′ position so that is formed the sugar buildup.
The joining of <em>one phosphate frames a nucleoside monophosphate, </em>the fuse of <em>two phosphates shapes a nucleoside diphosphate, </em>and the fuse of <em>three phosphates frames a nucleoside triphosphate.</em>
