<span>Because if we only classify animals by morphology, many animals have the same describable traits and physical structures.
Genes helped taxonomy better classify and aggregate animals.
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:
are the plants food
Explanation:
the nutrients is the energy for the plant, they give the plant energy.
Answer:
During translation process tRNA move from one binding site of ribosome (A site) towards P site.
Explanation:
Ribosome is composed of two sub units, one small and other large. It contain three binding sites for tRNA.
1. Peptidyl site:
It help in holding newly growing polypeptide chain of amino acid.
2. Acceptor site (A site):
It help in receiving and holding aminoacyl tRNA which hold amino acid that will be added to polypeptide chain.
3. Exit site (E site):
That site where tRNA leave its amino acid.
The process of translation consists of three main steps:
1. Initiation:
In this step mRNA bind to ribosomal sub unit.
2. Elongation:
The ribosome read the mRNA by joining with tRNA and help in the formation of polypeptide chain.
3. Termination:
When ribosome reach to stop codon translation stop.
When the process of translation is started, initiator tRNA carrier of methionine amino acid come and set on start codon (AUG) located in A binding site of larger subunit of ribosome. As ribosome move along mRNA attached tRNA to mRNA is shifted to p site from P to E site. It should be cleared that prolypeptide chain grow in nitrogen to carboxyl direction.
