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
Answer:
Surprising
Explanation:
This is surprising because the total number of planets in our solar system are nine which revolve around a central star i.e sun in different orbital paths.
Also, out of 9 nearly four planets i.e Mercury, Earth, Venus and Mars are terrestrial i.e having some land forms. Out of remaining 5 non terrestrial planets nearly four planets are gas planets (Jupiter, Uranus, Neptune and Saturn) and these planets are distantly positioned from the central star
Hence, the given discovery is surprising
Hydrosphere
Explanation:
- The dolphin swims in the hydrosphere.
- The hydropshere is the region occupied by water on the earth surface.
- They are the oceans, lakes, rivers, glaciers e.t.c
- The hydrosphere makes up 70% the total surface area on earth.
- Ocean occupies a whooping 95% of all.
- The hydrosphere is able to support aquatic life and this is why the dolphin with its streamlined body swims in this sphere.
