Answer:
C. The cell copies its organelles.
I don't really get your question sorry :(
When the dsDNA copies are then inserted into vectors and cloned into E. coli. the scientist has produced a cDNA library.
A collection of DNA fragments that have been cloned into vectors to identify and isolate desired DNA fragments is known as the DNA library. cDNA libraries and genomic libraries are the two types of libraries.
cDNA (Complementary DNA )library: cDNA is a DNA copy of an mRNA molecule that is produced by reverse transcriptase, a DNA polymerase that can use RNA or DNA as its template.
- These are made by using mRNA as their starting material as templates.
- They only represent genes in the genome that are expressed under particular conditions.
- Because cDNA lacks introns, prokaryotic cells can express it.

Answer:
Each protein is made up of a unique number and order of amino acids. The protein that is created has a specific job to do or a specific tissue such as muscle tissue to create. The structure of amino acids is fairly simple. Each amino acid has an amino group at its core with a carboxyl group and a side chain attached.
Explanation:
Answer:
The first option
Explanation:
The first option because in the water cycle, water does not change chemically but, it changes its physical form throughout the cycle. In other chemical cycles ,the element (such as carbon) changes chemically throughout its cycle making it the main difference between the water cycle and other chemical cycles.
