Why is it important for dna to condense into chromosomes

Biology
1 answer:
MrRa [10]4 years ago

Answer:

During mitosis, the condensation of chromosomes takes place which is important for cell in several ways. Each DNA is more than 2 meter long therefore to fit it in the small size of the nucleus and to prevent its tangling cell need to condense the DNA into small units.

Condensation of DNA forms an organized structure in the form of a chromosome that helps in easy separation of chromosome during the time of cell division.

The condensation is also required to form functional genes and to regulate the binding of proteins to these gene thereby regulating the gene activation. Therefore DNA needs to condense into chromosomes.

The process of translation in prokaryotes can occur faster than in eukaryotes because
Nimfa-mama [501]

Answer:

Transcription and translation occur simultaneously in prokaryotes.

Explanation:

Prokaryotes lack membrane-bound organelles and therefore, do not have a nucleus. Transcription and translation occur in the cytoplasm. As soon as the required length of mRNA is being formed, ribosomes join it and start the process of translation. Prokaryotic genes lack introns. The primary transcript formed by transcription in prokaryotes does not undergo splicing.

On the other hand, the process of transcription occurs in the nucleus in eukaryotes while translation occurs in the cytoplasm. The primary transcript formed by transcription in eukaryotes undergoes modifications to remove introns and to add a poly-A tail and 5' cap. Post-transcriptional modifications and spatial separation of two processes in eukaryotes result in slower translation than prokaryotes.

Which level of life includes all of the other levels in this list: organisms, cells, biosphere, molecules, ecosystems?
Vladimir79 [104]

Answer:

Biosphere

Explanation:

The biosphere is the part of the earth that supports life forms. It includes hydrosphere, atmosphere, and lithosphere. Various ecosystems, aquatic or terrestrial, are present in the biosphere. Biotic and abiotic components of a geographical region that interact with each other together make an ecosystem.

The biotic component of an ecosystem includes all the organisms present in it. Organisms may be unicellular or multicellular. All the organisms are made up of one or more cells. Cells are made up of various biomolecules that interact and enable cells to perform the life processes.
