Which of the following is a characteristic of eukaryotes but NOT of prokaryotes?

Biology
1 answer:
marshall27 [118]3 years ago
3 0

Answer:

b. The genetic material is surrounded by its own phospholipid bilayer, distinct from the phospholipid bilayer that surrounds the cell.

Explanation:

In eukaryotes genetic material is DNA and it is located in the well defined nucleus. The nucleus in eukaryotes is definite nucleus which is surrounded by by a unit membrane called nuclear membrane which is made of phospholipid bilayer. Whereas, in prokaryotes incipient nucleus is present which is not surrounded by nuclear membrane. Thus, option b. is correct.

Explain WHY photosynthesis and respiration are NOT able to create a cycle of energy?
jeka94

In a plant cell, photosynthesis and cellular respiration can both take place simultaneously. Plants carry out both photosynthesis and cellular respiration during the day. Cellular respiration continues because it provides the energy required for essential cell functions.

<h3></h3><h3>What role of  photosynthesis and respiration in plant?</h3>

Water and carbon dioxide are changed into oxygen and glucose during photosynthesis. The plant consumes glucose and produces oxygen as a byproduct.

Oxygen and glucose are transformed into water and carbon dioxide during cellular respiration. By-products of the process include carbon dioxide, water, and ATP, which is turned into energy.

To power cellular respiration, photosynthesis uses the energy it produces. During photosynthesis, solar energy is used, collected, and stored in the bonds of glucose molecules.

Therefore, photosynthesis and respiration not involve energy formation cycle.

1.) You are studying P120, a protein of 120 KDa that is continuously synthesized in eukaryotic cells. Its cellular concentration
irina1246 [14]

Answer:

1. P120 is degraded in the 26S proteasome

2. The 26S proteasome has a major role in protein degradation and is critical for protein homeostasis

3. Cell cycle and DNA replication are cellular processes regulated by the Ras and NFkB pathways

Explanation:

The proliferation-associated nucleolar protein (p120) is a protein known to be expressed during the interphase of the cell cycle, specifically in G1 and early S phase, where any problem with DNA replication trigger a checkpoint, i.e., a molecular cascade of signaling events that suspend DNA replication until the problem is resolved. In mammalian cells, the 26S proteasome is responsible for catalyzing protein degradation of about 80% (or even more) of their proteins. The 26S proteasome acts to degrade rapidly misfolded and regulatory proteins involved in the cell cycle, thereby having a major role in protein homeostasis and in the control of cellular processes. It is for that reason that inhibitors that block 26S proteasome function have shown to be useful as therapeutic agents in diseases associated with the failure of protein degradation mechanisms (e.g., multiple myeloma). The NF-κB are highly conserved transcription factors capable of regulating different cellular processes including, among others, cellular growth, inflammatory responses and apoptosis. Moreover, the MAPK/ERK pathway is able to transduce different signals received on the cell surface to the nucleus. The MAPK/ERK pathway is activated when a singling molecule binds to a cell receptor which triggers a signaling cascade that ends when a transcription factor induces the expression of target genes, ultimately producing a response in the cell (for example, the progression through the cell cycle).
