I would say A- Polysaccarides
Answer:
The correct order of formation of cDNA or complementary DNA are described below.
Explanation:
The DNA that is synthesized from mRNA with the help of reverse transcriptase enzyme is known as cDNA or complementary DNA.
Formation of cDNA
Step 1 Mature RNA is isolated
Step 2 Reverse transcriptase provided with a primer,synthesize a strand of cDNA without introns.
Step 3 The mRNA is hydrolyzed by raising the pH.
Step 4 A primer site is created on the single stranded cDNA molecule.
Step 5 A complementary DNA strand is synthesized forming double stranded cDNA molecule.
Answer: blood travels from the heart through arteries and blood travels to the heart through the veins.
