Is eukaryotic cells the timing of the cell cycle regulated by cyclins?
Yes, in eukaryotic cells, the timing of the cell cycle is regulated by cyclins. Cyclins are proteins that control the progression of the cell cycle by activating cyclin-dependent kinases (CDKs). The levels of different cyclins fluctuate throughout the cell cycle, signaling the cell to move from one phase to another.
Is true that all cells contain the same organelles?
Yes. The two main types of cells, Prokaryotic (mostly independent) and Eukaryotic (mostly dependent), are different so they both have different sets of organelles. Prokaryotic cells have less organelles than that of Eukaryotic cells; Prokaryotes typically have only ribosomes and a nucleoid (not to be confused with a nucleolus or nucleus), while Eukaryotes typically have ribosomes, a nucleolus (with inner nucleus), a rough and smooth ER (endoplasmic reticulum), Golgi apparatus, and mitochondria. Although, depending on their purpose, cell will have varying organelles that are adapted and/or specialized for carrying out one or more vital functions.
What is one of a family of closely related proteins that regulate the cell cycle in eukaryotic cells?
Cyclins are a family of closely related proteins that regulate the cell cycle in eukaryotic cells. They bind to cyclin-dependent kinases (CDKs) and help activate them to drive the cell cycle forward through its various phases.
What are the differences between independent and dependent variables?
Independent variables are controlled or manipulated by the researcher to determine their effect on the dependent variable. Dependent variables, on the other hand, are the outcome or response that is measured in an experiment. The independent variable causes a change in the dependent variable.
Which group of proteins control the cycle of a eukaryotic cell?
Cyclin-dependent kinases (CDKs) and cyclins are the main proteins that control the cell cycle in eukaryotic cells. The levels and activity of these proteins fluctuate throughout the different stages of the cell cycle, regulating the progression from one phase to the next.
Are hamsters prokaryotic or eukaryotic?
Plankton can be either eukaryotic or prokaryotic, it's dependent on the specific type of plankton. Plankton are divided into three different categories, Zooplankton, Bacterioplankton and phytoplankton. Zooplankton are eukaryotic.
What is the differences and similarities between independent and dependent?
Independent means you don't have to rely on other people to get by whereas dependent you have to depend on other people to get by.
The are the similarities and differences between a fiscal independent district and a fiscal dependent district.?
HAHA! Advanced School Finance at Nova? Cheeky...
What is the differences between independent and dependent variables?
One is dependent and one is independent
What are the similarities of microorganisms?
they are all directly or indirectly dependent on dead matters
What is the protein that regulate the timing of the cell cycle in eukaryotic cells known as?
CDK. Cyclin dependent kinases.
What is the similarities between independent and dependent variables?
Both variables and both part of an experiment.
What allows researchers to rule out differences among participants as the cause of differences in the dependent variable?
Researchers can rule out differences among participants as the cause of differences in the dependent variable by employing random assignment in experimental designs. This process ensures that each participant has an equal chance of being placed in any group, thereby controlling for individual differences. Additionally, using control groups and blinding techniques helps mitigate biases and isolate the effect of the independent variable on the dependent variable. Consequently, any observed differences can be attributed more confidently to the experimental manipulation rather than participant characteristics.
What are differences between platform dependent and platform independent?
Platform dependent requires the application to be run on specific hardware. independent will run on many kinds of hardware.
What is the similarities between sex influenced and sex limited traits?
Both sex-influenced and sex-limited traits are influenced by sex chromosomes. Sex-influenced traits are expressed differently in males and females due to hormonal differences, while sex-limited traits are only expressed in one sex due to anatomical or physiological differences. Both types of traits are dependent on the sex of the individual for their expression.
Is eukaryotic cells the timing of the cell cycle regulated by cyclins?
Yes, in eukaryotic cells, the timing of the cell cycle is regulated by cyclins. Cyclins are proteins that control the progression of the cell cycle by activating cyclin-dependent kinases (CDKs). The levels of different cyclins fluctuate throughout the cell cycle, signaling the cell to move from one phase to another.
How prokaryotes chromosomes differ from eukaryote?
A prokaryotic chromosome consists of a single molecule of DNA in the form of a closed loop. The chromosome is described as circular. A prokaryotic cell has only one chromosome. A eukaryotic chromosome is linear, not circular, in other words it has two ends, like a sausage. Each chromosome contains one molecule of DNA for the first half or so of interphase, then the DNA replicates, and the two DNA molecules remain together (as sister-chromatids) in the same chromosome for the rest of interphase. This does not happen in prokaryotic cells. Eukaryotic cells have more than onechromosome. A further difference: prokaryotic chromosomes consist only of a naked DNA molecule, but eukaryotic chromosomes also contain many molecules of proteins (mostly histones). The DNA is wound around these proteins.
