Answer:
EDTA is a chelating agent used to preserve samples for DNA extraction and as an anticoagulant
Explanation:
Ethylenediaminetetraacetic acid (EDTA) is a well-known chelating agent that binds metal ions (iron and calcium ions). In police cases, EDTA can be used for DNA extraction since this agent chelates metal ions in DNase enzymes which are contained in the samples, thereby reducing their activity and preserving DNA samples for a long time. Moreover, EDTA is also used as an anticoagulant for blood cells, which allows preserving the cellular components and the morphology of blood samples.

1.Three<span> major </span>types of RNA<span> are mRNA, or messenger </span>RNA<span>, that serve as temporary copies of the information found in DNA; rRNA, or ribosomal </span>RNA<span>, that serve as </span>structural<span> components of protein-making </span>structures<span> known as ribosomes; and finally, tRNA, or transfer </span>RNA<span>, that ferry amino acids to the ribosome to be assembled
2.</span>Transcription<span> is the </span>process<span> by which DNA is copied (</span>transcribed<span>) to mRNA, which carries the information needed for protein synthesis. </span>Transcription<span> takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.
3.</span><span>n molecular biology and genetics, </span>translation<span> is the </span>process<span> in which ribosomes in a cell's cytoplasm create proteins, following transcription of DNA to RNA in the cell's nucleus. ... In </span>translation<span>, messenger RNA (mRNA) is decoded by a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide.
4.</span>DNA is the genetic holder in our body ! for any message DNA has to convert in RNA and then protein resulting in all the traits we have !
so on transcription DNA information is converted to RNA and during translation into protein .... thus these protein helps in building our appearance , our Personalities every thing !
so we can say DNA influence physical trait !
The answer is Consistency
