Answer:
A cell that has duplicated chromosome cannot be in<u> G1 phase.</u>
Explanation:
- G1, G2 and S phase are the divisions of the interphase i.e. the resting phase of the cell cycle.
- A cell cycle has two phases; interphase and M-phase.
- During interphase the cell grows and in M-phase it divides.
- G1 is the Gap between the M-phase and the S-phase.
- G2 is the gap between the S phase and M phase.
- DNA replication is confined to the S part of interphase.
- Since G1 phase comes before the S phase , we can say that a cell that has duplicated chromosome cannot be in G1 phase.
Answer:
Lipids: Carbon, Hydrogen and Oxygen - monomers are glycerol and fatty acids.
Proteins - Carbon, Hydrogen, Oxygen and Nitrogen - monomers are amino acids
Carbs - No Phosphate. Carbon, Hydrogen and Oxygen - H:O ratio is 2:1 - monomers are (may have a ring structure)
Nucleic Acids - Examples are DNA and RNA. Carbon, Hydrogen, Oxygen, Nitrogen and Phosphate - monomers are nucleotide (sugar, phosphate, nitrogen base)
Lipids and proteins contain carbon, hydrogen, and oxygen. Both monomers are from certain types of acids. Carbs also contains carbon, oxygen, and hydrogen like lipids and proteins do. Carbs have monomers. Nucleic acids contain the same things founds in all three major macro molecules. Nucleic acids have nucleotide.
