What else can I help you with?
In eukaryotes all of RNA are transcribed or produced in the?
In eukaryotes, all RNA molecules are transcribed in the nucleus. This includes messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA). While some RNA molecules may undergo further processing and modification in the cytoplasm, their initial transcription occurs in the nucleus.
What is considered a chemical change?
A simple asnwer: a change which involve the modification of the initial molecule.
What is the function of the Cis face of the Golgi apparatus?
The Cis face of the Golgi apparatus functions as the receiving side, where newly synthesized proteins and lipids from the endoplasmic reticulum (ER) enter the Golgi. It is involved in the initial processing and sorting of these molecules before they move to the trans face for further modification and distribution. The Cis face plays a crucial role in ensuring that proteins are properly folded and tagged for their final destinations within or outside the cell.
What modifies proteins and lipids inside the cell?
Proteins and lipids are modified inside the cell primarily by the endoplasmic reticulum (ER) and the Golgi apparatus. The rough ER is responsible for the synthesis and initial folding of proteins, while the smooth ER is involved in lipid synthesis. After initial modifications, proteins and lipids are transported to the Golgi apparatus, where they undergo further processing, such as glycosylation or phosphorylation, before being sent to their final destinations. These modifications are crucial for the proper functioning and localization of cellular components.
Experiments and chemical principles suggest that powered the synthesis of complex organic compounds on prebiotic Earth. 1.oxygen 2.water currrents or 3. lightning or intesue uv rays 3?
Lightning or intense UV radiation would have played a key role in the synthesis of complex organic compounds on prebiotic Earth. These energy sources could have driven chemical reactions that led to the formation of organic molecules like amino acids necessary for life. Oxygen and water currents are important for the development of life once these organic molecules were formed, but are not typically involved in the initial synthesis process.
When a thesis and antithesis meet they often form a?
synthesis. This is a process where the conflicting ideas merge to create a new, more complex understanding that incorporates elements of both the thesis and antithesis. This synthesis represents a higher level of thought that resolves the initial conflict.
What initial product does hydrolysis of starch produce?
The initial product of hydrolysis of starch is maltose, which is a disaccharide composed of two glucose molecules. This process breaks down the starch molecule into smaller sugar units that can be further broken down and metabolized by the body for energy.
The modifies proteins delivered from the rough endoplasmic reticulum.?
The rough endoplasmic reticulum (RER) is responsible for the synthesis and initial modification of proteins destined for secretion or for use in membranes. Ribosomes attached to the RER translate mRNA into polypeptide chains, which enter the RER lumen where they undergo folding and post-translational modifications, such as glycosylation. Once properly modified, these proteins are packaged into vesicles and sent to the Golgi apparatus for further processing and sorting. This system ensures that proteins are correctly modified and directed to their appropriate cellular locations.
Why methionine is removed from protein in post translation modification?
Methionine is the amino acid associated with the AUG sequence on mRNA. The AUG sequence also indicates the beginning of a gene. Though the AUG sequence is necessary for gene expression, methionine is not necessary for all proteins. This is why it is usually removed after translation.
What performs the same function as golgi body?
The endoplasmic reticulum (ER) is responsible for producing, processing, and transporting proteins and lipids within the cell, similar to the Golgi apparatus. While the Golgi apparatus packages and modifies proteins received from the ER, the ER is involved in the initial synthesis and folding of these molecules.
Will you be able to get a child's father for back child support now although you did not request it on your initial child support order?
If you file for modification of the original order and it is granted, yes.
What is the initial cause of the dissociation of water molecules into hydrogen and hydroxide ions?
The initial cause of the dissociation of water molecules into hydrogen and hydroxide ions is the breaking of the hydrogen-oxygen bonds within the water molecule due to thermal energy. This process is facilitated by the natural tendency of water molecules to ionize into H+ and OH- ions.
