How can cells regulate gene expression to control their functions and responses?
Cells can regulate gene expression by turning genes on or off, controlling the amount of proteins produced. This process helps cells control their functions and responses to different signals and environments.
Which is true about eukaryotic gene regulation?
Most eukaryotic genes are controlled individually and have regulatory sequences that are much more complex than those of the lac operon. (this answer above was found in my Biology text book too so it is correct) :)
What has chromosomes packed inside a nucleus?
Eukaryotic cells have chromosomes packed inside a nucleus. Eukaryotic organisms, including plants, animals, fungi, and protists, have this type of cellular organization. Each chromosome contains DNA and associated proteins that help regulate gene expression and cell functions.
Cells that have a nucleus are called?
Eukaryotic cells.
Is the structure in eukaryotic cells that controls cell activities and contains genetic material?
The structure in eukaryotic cells that controls cell activities and contains genetic material is the nucleus. It houses the cell's DNA and is responsible for regulating gene expression and coordinating cellular functions.
Eukaryotic are controlled by what group of proteins?
Eukaryotic cells are controlled by a group of proteins called transcription factors. These proteins regulate the transcription of genes by binding to specific DNA sequences and influencing the expression of those genes. They play a crucial role in gene regulation and cell function in eukaryotic organisms.
Eukaryotic DNA sequences called enhancers have a function similar to the of prokaryotic operons?
Eukaryotic DNA sequences called enhancers have a function similar to the operators of prokaryotic operons. In eukaryotic cells, repressor proteins inhibit transcription by binding to silencers.
Can eukaryotic Cells control gene expression by using transcription factors?
Yes, eukaryotic cells can control gene expression using transcription factors. Transcription factors are proteins that regulate the transcription of specific genes by binding to DNA and either promoting or inhibiting gene expression. They play a crucial role in controlling when and where genes are turned on or off in response to various signals and cellular conditions.
Protein known as regulate the timing of the cell cycle in eukaryotic cells?
Cyclins
What do prokaryotic and eukaryotic cells use to turn certain genes on or off?
Prokaryotic cells use regulatory proteins like repressors or activators that bind to the DNA to turn genes on or off. Eukaryotic cells use a combination of transcription factors, chromatin remodeling complexes, and non-coding RNAs to regulate gene expression.
Proteins called growth factors regulate the timing of the cell cycle in eukaryotic cells?
no
How does a cell regulate the cell cycle?
The chemicals that regulate the cell cycle are called cyclins. They work by controlling the timing of the cell cycle in eukaryotic cells.

What is the protein that regulate the timing of the cell cycle in eukaryotic cells known as?
CDK. Cyclin dependent kinases.
Why prokaryotic cells are not prefer for eukaryotic gene expression?
Actually, for some uses prokaryotic cells are just fine for eukaryotic gene expression. That said bacteria are deficient in quite a lot of the post-translational modification systems that eukaryotes use, such as glycosylation. Since those post-translational modifications can actually be important to the protein's function you might choose a eukaryotic expression system to preserve them.
The nuclei of eukaryotic cells are characterized by?
The nuclei of eukaryotic cells are characterized by being membrane-bound organelles that house the genetic material in the form of chromosomes. They contain the nucleolus, where ribosomal RNA synthesis occurs, and pores that regulate the transport of molecules in and out of the nucleus. The nucleus plays a key role in regulating gene expression and coordinating cellular activities.
