How do prokaryotes and eukaryotes differ in how they store genetic material?(1 point) Responses Prokaryotes lack a true nucleus. Prokaryotes lack a true nucleus. Eukaryotes lack a true nucleus. Eukaryotes lack a true nucleus. Prokaryotes have RNA instead of DNA. Prokaryotes have RNA instead of DNA. Eukaryotes have RNA instead of DNA
The correct response is:
Prokaryotes lack a true nucleus. Eukaryotes have a true nucleus, which is separated from the cytoplasm by a nuclear membrane. This nucleus contains the genetic material, DNA, in eukaryotes. In prokaryotes, however, the DNA is not contained within a nucleus and is instead located in the cytoplasm.
Prokaryotes and eukaryotes differ in how they store genetic material. Prokaryotes lack a true nucleus, while eukaryotes have a true nucleus. This difference affects how their genetic material is stored.
Prokaryotes, such as bacteria, have a simple cellular structure without compartments. Their genetic material, which is DNA, is not enclosed within a nucleus. Instead, it is present in the cytoplasm as a single, circular chromosome. Some prokaryotes may also have smaller circular DNA molecules called plasmids.
On the other hand, eukaryotes, which include organisms like plants, animals, fungi, and protists, have a more complex cellular structure. They have a defined nucleus that houses their genetic material. Eukaryotic DNA is organized into multiple linear chromosomes that are contained within the nucleus.
So, to summarize, prokaryotes store their genetic material as a single circular DNA molecule in the cytoplasm, while eukaryotes store their genetic material as multiple linear chromosomes within the nucleus.
Prokaryotes and eukaryotes differ in how they store genetic material primarily in terms of their cellular organization and the form of their genetic material.
1. Prokaryotes lack a true nucleus: Prokaryotic cells do not have a membrane-bound nucleus. Instead, their genetic material, which is in the form of a single, circular DNA molecule, is found in the cytoplasm of the cell. The DNA is not enclosed within a nuclear membrane.
2. Eukaryotes have a true nucleus: Eukaryotic cells, on the other hand, possess a true nucleus, which is a membrane-bound organelle that houses their genetic material. The DNA in eukaryotes is organized into multiple linear chromosomes, which are enclosed within the nuclear membrane.
3. Prokaryotes have DNA: Both prokaryotes and eukaryotes store their genetic information in the form of DNA (deoxyribonucleic acid). DNA is a double-stranded molecule that carries the genetic instructions for the development and functioning of an organism.
4. Eukaryotes may have RNA too: While eukaryotes primarily store their genetic material as DNA, they also utilize RNA (ribonucleic acid) as an intermediary molecule in the process of gene expression. RNA plays a crucial role in protein synthesis and regulation of gene expression in eukaryotes.
In summary, prokaryotes lack a true nucleus and store their genetic material as a single, circular DNA molecule in the cytoplasm, while eukaryotes have a true nucleus and store their genetic information as multiple linear chromosomes within the nuclear membrane. Both prokaryotes and eukaryotes primarily utilize DNA, but eukaryotes may also utilize RNA in gene expression processes.
What would happen to a cell that lacked smooth endoplasmic reticulum?(1 point) Responses It would not be able to produce tRNA. It would not be able to produce tRNA. It would not be able to replicate DNA. It would not be able to replicate DNA. Its cell membrane would be impermeable. Its cell membrane would be impermeable. It would not be able to make lipids.
The correct response is: It would not be able to make lipids.
Smooth endoplasmic reticulum (SER) is responsible for lipid synthesis and metabolism within the cell. It does not play a direct role in tRNA production, DNA replication, or cell membrane permeability. Without smooth ER, the cell would lack the ability to produce lipids, which are important for various cellular processes, such as membrane formation, hormone production, and energy storage.
you sure?
I apologize for the confusion. Smooth endoplasmic reticulum (SER) is indeed responsible for lipid synthesis and metabolism within the cell. Without SER, the cell would not be able to produce lipids. The correct response is: It would not be able to make lipids.
What is the relationship between ribosomes and rough endoplasmic reticulum (ER)?(1 point) Responses Rough ER produces the polypeptide chains that ribosomes need to make protein. Rough ER produces the polypeptide chains that ribosomes need to make protein. Rough ER is the subunit of ribosomes that makes proteins Rough ER is the subunit of ribosomes that makes proteins Ribosomes attached to rough ER make proteins that the rough ER then transports around the cell Ribosomes attached to rough ER make proteins that the rough ER then transports around the cell Ribosomes transport proteins made by rough ER to the Golgi apparatus.
The correct response is: Ribosomes attached to rough ER make proteins that the rough ER then transports around the cell.
Ribosomes are responsible for protein synthesis in the cell. They are found either free-floating in the cytoplasm or attached to the rough endoplasmic reticulum (ER). When ribosomes are attached to the rough ER, they synthesize proteins that are directly transported into the ER for further processing and packaging. The rough ER plays a crucial role in protein synthesis and sorting, as it provides a surface for ribosomes to produce proteins and then helps transport those proteins to other parts of the cell or to the Golgi apparatus for further modification and distribution.
