a scientist isolates all of the mrnas in a kidney cell and reverse transcribes them into dsdna. the dsdna copies are then insert
SVETLANKA909090 [29]

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.

What is a major difference between facilitated diffusion and active transport?
xenn [34]

Answer:

The correct option is<em> A. Active transport moves substances against the concentration gradient.</em>

Explanation:

Active transport can be described as a transport mechanism in which molecules tend to move against the concentration gradient i.e from an area of lower concentration to an area of higher concentration. Energy is needed for this process to occur.

Facilitated diffusion can be described as a phenomenon is which molecules move along the concentration gradient i.e from a higher concentration to a lower concentration with the help of trans- membrane integral proteins
