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:
High, Low
Explanation:
Wind blows air on the surface of the earth from a high pressure center to a low pressure center (this is depicted in the image attached). The area between the two "centers" is referred to as pressure gradient. The warm air in the region of the low pressure center then rises up into the atmosphere. The warm air then cools up in the atmosphere and then passed down back to the earth's surface
The answer is 99.
Amino acids <span>contain a carboxyl group (carbon-containing) and an amino group (nitrogen containing). Proteins are made by forming peptide bonds between the carboxyl and amino group of amino acids.
</span>If a protein is made of 100 amino acids, that means there are 99 peptide bonds (because the last, 100th amino acid will not bind the next (101st) amino acid). For each peptide bond that is created, one oxygen atom and two hydrogen atoms are taken. Therefore, one water molecule is created for each peptide bond. If there are 99 peptide bonds, 99 water molecules are created.
