Answer:
Together, adenine and thymine compose 70% of the segment. This means that 30% of the section is composed of guanine-cytosine pairs. Since these two bases will be equal in quantity, 15% of the DNA section will be cytosine bases.

Answer:
when plate movement happen,it uncovers old rocks??
Explanation:
Answer:
Viruses can only replicate themselves by infecting a host cell and therefore cannot reproduce on their own.
Explanation:
Prokaryotic translation Eukaryotic translation
1. The mRNA of Prokaryotic translation is monocistronic while the mRNA of Eukaryotic translation is known to be polycistronic.
2. In Prokaryotic translation, transcription and translation occurs at the same time in the cytoplasm while transcription occurs at the nucleus, as translation is seen at the cytoplasm of Eukaryotic translation
3. Prokaryotic translation do not undergo post-transcriptional modification, prior its translation of mRNA. Eukaryotic translation produces pre-mRNA from transcription as it undergo modification into mRNA before it's being transported to the cytoplasm for translation.
4. Prokaryotic translation its simple with only one initiation mechanism and a few amount of factors for the whole translation Unlike Euaryotic translation that possess two initiation mechanisms: cap- dependent and cap-independent plus varying factors and enzymes for the whole translation.
5
Prokaryotes can translate 20 amino acids per second and requires 2 release factors-RF1 and RF2
Eukaryotes can translate only one amino acid per second and requires only one release factor-eRF1
6
Post-translational modification takes place in the cytoplasm.
It can take place in Endoplasmic reticulum or Golgi bodies or cytoplasm
Answer:
The answer to these questions are the following:
1. sucrose solution (higher concentration of water molecules in the onion cells) >> red onion cells will shrink >> smaller diameter
2. distilled water (higher concentration of water molecules in the surrounding solution) >> red onion cells will become turgid >> higher diameter
Osmosis refers to the movement of a solvent (usually water molecules) across semipermeable biological membranes, which occurs from a region of higher concentration to a region of lower concentration. There are three classes of solutions that have different effects on cells due to the process of osmosis:
1. In a hypotonic solution, the cells will become turgid
2. In an isotonic solution, the cells will become flaccid.
3. In a hypertonic solution, the cells will shrink (plasmolysis)
When plant cells are placed into a hypertonic solution where there is a greater concentration of solute outside the cells (as in this case sucrose solution), water molecules will move from inside the cells to outside the cells, thereby cells will shrink due to water loss
When plant cells are placed into a hypotonic solution that is diluted in comparison to the content of the cell (as in this case plant cells placed in distilled water) water molecules will move from outside the cells to inside the cells, thereby cells will become turgid.
