!!!!!How do radioactive elements help scientists establish how old rocks and fossils are?!!!!
MAVERICK [17]

Answer:

I will give a hypothesis. Just like a tree, when you cut a tree by its trunk, you will the rings. The rings around it represents the tree's age. So when you cut rock, the pores in the rock determine whether it is an old rock or a fossil rock.

Explanation:

The reason is, if it is limestone and it is an old rock, the pores will be slightly big and if the limestone is a fossil rock, then the pores will be bigger due to leaching or denaturing of the minerals in the rock through the ages.

Plasmids are small circular DNA molecules found in bacteria that replicate separately from chromosomes. Why are plasmids essenti
oksano4ka [1.4K]

Answer:

DNA from a gene of interest can be inserted into a plasmid, then the modified plasmid can be inserted into a bacterial cell to replicate a gene of interest many times.

Explanation:

Plasmids are the extra-chromosomal circular DNA present in bacterial cells. Plasmids are able to replicate themselves independent of genetic DNA. Their ability to self replicate allows them to maintain themselves in the bacterial cells. This is why plasmids are used as cloning vectors in recombinant DNA technology.

A gene of interest is isolated from the donor cell and is inserted into the plasmid. The recombinant plasmid is introduced into bacterial cells where it replicates the ligated desired gene and allows the gene cloning. For example, the human insulin gene is ligated with plasmid and the recombinant plasmid is introduced in <em>E. coli</em> where it replicates the human insulin gene and allows the production of desired copies of the gene.
