It is true that cells spend most of their time dividing. In fact, they spend 78% of their "life" in interphase.
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
c. food production is the answer
Hypertonic, because the water is leaving the cell to get to a higher (hyper) amount of solute.
Answer:
Binary fission is different from mitosis and meiosis because it occur in prokaryotic cells. And prokaryotic cells does not have nucleus like the eukaryotic cells and there is not mitotic spindle formation during binary fission compared to mitosis and meiosis.
Explanation:
Binary fission is a process of cell division where a single cells divide into two or more parts and the parts regenerate into another organisms which resembles the parent organisms. This occur only in prokaryotic cells and is very different from mitosis and meiosis that occur in eukaryotic cells because prokaryotic cells lack nucleus and no spindle formation in the nucleus.
Mitosis occur in eukaryotic cells because they have nucleus and membrane bound organelles and is the process where a parent cell divide to produce two daughter cells that are genetically identical to the parent cell and each cell having the same number of chromosomes of the parent cell.
Meiosis is a type of cell division that occur in eukaryotic cells and it occur in sex cells where a single cell divide into four daughter cells with each having half number of parent cell chromosomes.
