DNA is a nucleic acid involved in heredity, or the passing down of genetic traits from one generation to the next. DNA consists
Phoenix [80]

Nitrogenous base DNA consists of four unique nucleotides that each contain one unique nitrogenous base—adenine (A), thymine (T), cytosine (C), or guanine (G).

The specific arrangement of these four bases within the DNA of each organism gives that organism its unique traits; here are the arrangements:

-<u>Adenine</u> is paired with <u>Thymine</u> (think of A for apple and T for tree)

-<u>Cytosine</u> is paired with <u>Guanine</u> (think of C for car and G for garage)

Which discovery supported the endosymbiotic theory?
alexdok [17]

The right answer is A.) DNA in mitochondria .

Eukaryotic cells, with their many intracellular organelles, have long been considered progeny of prokaryotes that would have become more complex as a result of genetic mutations. But from the 1960s, biologist Lynn Margulis proposed an alternative explanation that was first received coldly by the scientific community. His endosymbiotic theory, proposed in a more formal way in a 1981 book, proposes that eukaryotic cells as we know them today would be the result of a series of symbiotic associations with different prokaryotes.

Mitochondria and chloroplasts also have their own DNA that is not trapped in a nucleus, which is also the case with prokaryotes. However, the proteins encoded by this DNA do not cover all mitochondrial proteins. The prokaryote is thought to have lost some genes to the nucleus of the cell, a process known as "endosymbiotic gene transfer". For this reason, mitochondria and chloroplasts are now host-dependent for the synthesis of most of their components.

tatiyna

Answer:

<em>The correct option is C) It does not depend on insect pollination.</em>

Explanation:

Angiosperms can simply be described as the plants which produce flowers whereas gymnosperms are the plants which do not produce flowers.

Both, the gymnosperms and the angiosperms, are capable of producing seeds. However, the seeds of the angiosperms are enclosed in an ovary. The seeds of gymnosperms are not enclosed.

<u><em>One of the major differences between gymnosperms and angiosperms is that the angiosperms have to depend on animals for pollination. On the other hand, the seeds of gymnosperms are spread through the wind and are pollinated.</em></u>
