What are the roles of covalent bonds and hydrogen bonds in the structure of DNA?
Vinil7 [7]
For the answer to the question above,
 <span>DNA is made up of two nucleotide strands. The nucleotides are connected together by covalent bonds within each strand. The sugar of one nucleotide forms a covalent bond with the phosphate group of another. The two strands themselves are connected by hydrogen bonds. The hydrogen bonds are found between the bases of the two strands of nucleotides. Adenine forms hydrogen bonds with thymine whereas guanine forms hydrogen bonds with cytosine. This is called complementary base pairing</span>

Which of the following are true about outgroups? a. They help identify plesiomorphic traits in the phylogeny b. They are a taxa
Tanzania [10]

Answer:

The the above statements are true about out groups.

Explanation:

a. Out groups called as the more related organism that determine the evolution of the in group traits.

Plesiomorphy means the ancestral character that determines the phylogenetic evolution of an individual.For example, presence of spinal column is a plesiomorphic character of mammals that are present in fish, amphibia,reptiles, birds etc.

b. In groups are diverge from the out group but the out groups are used as a point to compare with the in groups as it is essential to determine the evolution of a trait in a phylogeny.

c. Autapomorphic traits contain distinctive characters that is unique and found in a particular taxa but not found in a any other out group taxa.

d.Out groups are less evolved as they contain ancestral features and during evolution they are replaced by advance characters that are presently in in group traits.Out group study is required to study the evolutionary relationship of the in group trait.
