Define the following terms. Drag and drop the words into the appropriate blanks to complete the sentences.
FrozenT [24]

Answer:

1. replication

2. gene

3. strand polarity

4. translation

5. complementary base pairing

6. chromosome

7. antiparallel

8. transcription

9. allele

Explanation:

1. Replication is the process by which DNA is duplicated or the process of making another copy of DNA.

2. Gene is the physical unit of heredity i.e a segment of DNA transferred from parents to offsprings. A gene also encodes a useful products such as protein.

3. A DNA strand is a polar molecule, which is attributed to the phosphate group at the 5'-end of DNA and the hydroxyl group at the 3'-end of DNA.

4. Translation is the process whereby the information in a mRNA molecule is used to synthesize a protein.

5. Complementary base pairing is a phenomenon whereby Adenine (A) binds to thymine (T), guanine (G) binds to cytosine (C).

6. A chromosome contains of single long molecule of DNA coiled together around histone proteins. The chromosome is associated with different types of proteins.

7. In the double-stranded DNA molecule, one strand runs from 5' to 3' and the other runs from 3' to 5'. This is called ANTIPARALLEL nature of DNA.

8. Transcription is the process by which a DNA molecule is used to synthesize a mRNA single strand.

9. Allele is the alternative or contrasting form of a gene. Each allele is contributed by each parent

Andre45 [30]

The use of a thermophilic DNA polymerase such as Taq polymerase prevents the denaturation of the enzyme during the heating that is important to separate the newly synthesized strand. So using this enzyme simplifies the PCR technique and increases its efficiency.

Taq DNA polymerase is highly efficient, when it reaches the optimum temperature, it becomes fully functional. It also has a half-life of over two hours (at 92°C), high amplification capacity, and it can add upto 150 nucleotides per second.  It is "special" enzyme because it comes from the bacterium Thermus aquaticus, which lives in hot springs. It is therefore thermostable even at high temperatures, while other polymerases (e.g. E. coli) are not.
