ddNTPs have a hydrogen at 3' position which terminates synthesis of DNA.
ddNTPs is the abbreviated form for dideoxynucleotides triphosphates. They are known as chain elongating inhibitors. The Sanger method is a sequencing technique that is used to increase the number of DNA copies. The DNA synthesis requires magnesium ions, a single-stranded DNA template, oligonucleotide primer, and nucleotide precursors like dATP, dGTP, dTTP, and dCTP. Also, DNA polymerase is required which is an essential component for DNA synthesis.
The Sanger sequencing method is a significant process evident by its use in Human Genome Project which helped scientists in sequencing the human genome. The small sequenced fragments are joined together to form large regions subsequently forming chromosomes.

Answer: "Hair follicles are divided into three parts : the <em>infundibulum</em>, the <em>isthmus</em> and the <em>bulb</em>."
"Each hair contains protein called Keratin. "
Explanation:
Answer: B
Explanation: Multiple different combinations of bases (A, G, C, T) can code for the same amino acid. This means that there are more possible combinations of the bases than there are amino acids. There are 20 amino acids and the four bases can have up to 64 different codon combinations.
Answer: B:The drought decreased the grass and vegetation on the ground, leaving only vegetation on shrubs and trees above the ground. Natural selection selected for the tortoises with the domed shells and hoods.
Explanation:
It has the strongest winds in the solar system
Its orbit was used to predict the existence of another planet
It is most well-known for its rings
It has a giant storm three times the width of Earth.
