Answer:
A Ligase
B False
C To separate the double‑stranded DNA
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology laboratories in order to make millions of copies of a specific sequence of DNA. PCR requires deoxynucleotide triphosphates (dNTPs) to synthesize new copies of the target DNA fragment, a thermostable DNA polymerase that adds nucleotides to new DNA strands, and primers that attach to complementary ends at each DNA strand. PCR has three phases: 1-Denaturation, where the double-stranded DNA molecule is heated to separate it into two single (separated) strands; 2-annealing, where the temperature is lowered in order to allow the primers to attach each DNA strand, and 3- extension, where the temperature is increased (again), and the thermostable DNA polymerase adds the appropriate dNTPs to new DNA strands. In consequence, annealing occurs at the lowest temperature. Moreover, during the denaturation stage, the temperature is increased at 90–95°C in order to denature the DNA strands into single strands.
Answer:
I believe the answer is:
They both have different phosphate groups in their backbones
Answer: Fungi
Explanation: Antibiotics are chemicals that kill or inhibit the growth of bacteria and are used to treat bacteria infections. They are produced in nature by soil bacteria are fungi.
Plate boundary theory by Alfred Wegener
Toddler - A child 12 to 36 months old
Embryo - An embryo is an early stage of development of a organism
Foetus - An unborn human more than eight weeks after conception
Neonate - A newborn Child or an infant less than four weeks old
Infants - The term "infant" is typically applied to young children under one year of age
Explanation:
An embryo is the early stage of human development in which organs are critical body structures are formed. An embryo is termed a fetus beginning in the 11th week of pregnancy, which is the 9th week of development after fertilization of the egg.
