One big way to tell a difference is that DNA is double stranded, in the shape of a double helix, while RNA is single stranded. (This is why RNA can leave the nucleus and DNA cannot) There are also factors that affect the difference like how DNA contains thymine, and when RNA makes copies of it, it becomes uracil.
Answer:
Paradoxides pinus belong to the life forms that existed during the Cambrian period.
Explanation:
Paradoxides pinus is a form of trilobites that thrived all over the world during the middle of the cambrian period as per index fossils. Structurally, they are found to possess semi circular like head with the cheeks curving into structures that resemble spines. Their eyes are sickle shaped for they are believed to have all round vision. The exoskeleton is large and often flattened or oval in shape with greatest width along the re-curved spine.
Answer:
Bacteria.
Explanation:
CRISPR (clustered regularly interspaced short palindromic repeats) are the DNA sequences and Cas9 (CRISPR-associated protein 9) is an enzyme used to identify the CRISPR sequence.
The genetic engineer has discovered gene sequence and isolated from the same organism as CRISPR-Cas9. The organism have been isolated from the bacteria as the CRISPR sequence is present in the genomes of prokaryotes especially bacteria.
Thus, the answer is bacteria.
Polymerase chain reaction is a method of preparing DNA for forensic analysis .
<u>Explanation:</u>
- In order to prepare DNA for the forensic analysis, it must be replicated in an amount that is easily detectable in any biomedical instrument for the analysis.
- This polymerase chain reaction is a process that is helpful in preparing the DNA in huge amounts by amplifying it.
- The mitochondrial DNA and nuclear DNA are the two types of DNA used in the forensic analysis.
