What activity must mRNA do in traveling from DNA to protein synthesis sites in eukaryootic cells that does NOT occur in prokaryotic cells?
In eukaryotic cells, mRNA must undergo processing, which includes capping, polyadenylation, and splicing, before it can be transported from the nucleus to the cytoplasm for protein synthesis. This processing is essential for stability and translation efficiency. In contrast, prokaryotic cells do not have a nucleus, and their mRNA is translated directly after transcription without such modifications.

Antitermination of RNA synthesis is a major mechanism of regulation in?
Antitermination of RNA synthesis is a major mechanism of regulation in prokaryotic gene expression. It allows transcription to continue past termination signals in certain conditions, enabling the production of full-length transcripts. This mechanism often involves regulatory proteins that interact with mRNA secondary structures to modulate RNA polymerase activity.
What are properties of life shared by prokaryotic cells and eukaryotic cells but not with viruses?
Both prokaryotic and eukaryotic cells exhibit key properties of life, including the ability to grow, reproduce, respond to stimuli, and maintain homeostasis. They are composed of cellular structures that facilitate metabolic processes, such as energy production and protein synthesis. In contrast, viruses lack cellular organization, cannot reproduce independently, and do not carry out metabolic processes on their own, relying instead on host cells for replication and activity.
How does lysosome affect prokaryotic cells?
Lysosyme is an enzyme with Beta glucosidase activity which degrades the bounds of Pepdioglycan. the main carbohydrate of bacterial cell wall. This leads to the dead of sensitive bacteria( prokaryotes)
Is ribosomes the most common organelle in a cell?
Yes, ribosomes are considered one of the most common organelles in a cell, as they are essential for protein synthesis. They can be found freely floating in the cytoplasm or attached to the endoplasmic reticulum, forming rough ER. Since all cells require proteins for various functions, ribosomes are abundant in both prokaryotic and eukaryotic cells. However, the exact number can vary depending on the cell type and its activity level.
Why synthesis phase is a good name for sub-phase of interphase?
The synthesis phase, or S phase, is a fitting name for this sub-phase of interphase because it is primarily focused on the synthesis of DNA. During this time, the cell replicates its genetic material to ensure that each daughter cell receives an identical set of chromosomes. This critical process of DNA synthesis is essential for cell division and maintaining genetic continuity. Additionally, the term "synthesis" reflects the fundamental biological activity occurring during this phase.
In prokaryotes most of the control of protein synthesis occurs at the level of what?
In prokaryotes, most of the control of protein synthesis occurs at the level of transcription initiation. This is achieved through the regulation of RNA polymerase activity, binding of transcription factors, and modulation of promoter sequences. Ribosomes then translate the mRNA into proteins following transcription.
Antitermination of RNA synthesis is a major mechanism of regulation in?
Antitermination of RNA synthesis is a major mechanism of regulation in prokaryotic gene expression. It allows transcription to continue past termination signals in certain conditions, enabling the production of full-length transcripts.

What is activation -synthesis theory?
dreams are a byproduct of brain activity during sleep

What adjectives are associated with the activation-synthesis hypothesis?
Bizarre, meaningless, and random reflect the nature of the activation-synthesis hypothesis since dreams are totally the result of brain activity.

What part controls the activity of a cell?
The answer is nucleus :)
In the activation-synthesis model of dreaming what is synthesized?
In the activation-synthesis model, dreams are believed to be the brain's effort to make sense of random neural activity during sleep. The brain synthesizes this activity into a narrative or story, creating the content of our dreams.
WHAT model of dreaming proposes that dreams are side-effects of neural activity in subcortical areas of the brain?
activation-synthesis model
What is enzyme synthesis?
Enzyme synthesis is the process by which cells make enzymes through transcription and translation of the enzyme's gene into a functional protein. This involves the production of mRNA from DNA in the nucleus, and the subsequent translation of this mRNA into the enzyme in the cytoplasm. Enzymes are essential for catalyzing biochemical reactions in cells.
What has the author Naomi Raeburn written?
Naomi Raeburn has written: 'The synthesis, reactions and potential biological activity of oxindolespirobicycloheptanes and octanes. 1978'
The activation-synthesis theory says that: (Apex)?
C. Dreams are a by-product of brain activity during sleep.
