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.

Komok [63]

Answer: C. Cells in meiosis have unique genetic information

Explanation: Meiosis is the cell division that forms four daughter cells from one parent cell. It includes two successive divisions called as meiosis I and meiosis II. Crossing over during prophase I of meiosis I imparts new gene combinations to the daughter cells of meiosis. Hence, daughter cells formed by the end of meiosis have some new gene combinations, that is, unique genetic information.
