How does molecular genetics add to our understanding of genes is by simply </span>studying them. <span> Molecular genetics is scientific study of composition of genes. This field is a subcategory of biology and heredity which is responsible for unearthing and delving the anatomy and physiology of the genes. </span>This field helps us to understand and find evidence in the compounds, substances and elements found and synthesized in our genes and what contains in our nucleic acides –RNA and DNA –framework of our chromosomes. <span>And also the origin and history of how genes came to be. These are codes and like-signals that makes us who we are in a macro-perspective.<span>

Answer:
20%
Explanation:
cytosine = guanine = 30%
cytosine + guanine = 60 %
adenine + thymine =100% - 60% = 40 %
thymine = 20%
Answer:
Option D, at the branch tips
Explanation:
Phylogeny tree is just like a family tree in which the roots of the tree that are its base represents the ancestral lineage. While moving towards the branches , the time is considered to be moving forwards as the organism which lie at the tip of the branches are the ones which have evolved from the ancestral lineage lying at the base. Thus, the branches at the end of a tree are the ones which have the most recently evolved organism.
Thus, option D is correct
Answer:
Yes they are two different things!
Explanation:
Chemistry is more basic to existence-it is the study of the composition of matter and all associated structures, properties, and reactions. This includes, but is not limited to, biological matter. Biology meanwhile is focused entirely on biological organisms.
