What hormone directly activated vir gene in agrobacterium Ti plasmid?
The hormone that directly activates the vir gene in Agrobacterium Ti plasmid is acetosyringone. It induces the expression of the vir genes, triggering the transfer of T-DNA from Agrobacterium to plant cells.
What directly controls how cells are formed all their activites?
The dna
Describe how animal cells can be transformed by directly injecting DNA?
Animal cells can be transformed by directly injecting DNA using a technique known as microinjection. In this process, a needle is used to deliver the desired DNA directly into the nucleus of the cell. The injected DNA can then be integrated into the cell's genome, leading to genetic modifications or expression of new proteins.
Where would steroid hormones most likely interact with their target cell?
Steroid hormones typically interact with their target cells inside the cell, specifically in the cytoplasm or nucleus. Once inside, they bind to specific receptor proteins, forming hormone-receptor complexes that can then modulate gene expression and alter cellular processes.
What is an Alykylating drug?
Alykylating drug-- A drug that kills cells by directly damaging DNA.
What is extracted from cells for DNA microarray technology?
RNA is extracted from cells for DNA microarray technology. RNA is then converted into cDNA (complementary DNA) through reverse transcription before being used in the microarray analysis.
A plasmid that contains a gene for human growth hormone is and example of what?
A plasmid containing a gene for human growth hormone can be used in genetic engineering to produce recombinant human growth hormone. This plasmid can be introduced into host cells, such as bacteria, for the production of the hormone on a large scale.
The ability of cells to pass on their characteristics to new cells is most directly related to the ability of?
Cells to replicate their DNA accurately during cell division. When a cell divides, it must replicate its DNA to pass on genetic information to the new cells. Errors in DNA replication can lead to mutations and changes in characteristics passed on to new cells.
In circumstances where the body requires prolonged or increased levels of a hormone the DNA of target cells will specify the synthesis of more receptors on the surface of the cells of the target organ?
Yes, this process is known as upregulation. When the body needs higher levels of a hormone for an extended period, the target cells can increase the number of receptors on their surface through gene expression to enhance sensitivity and response to the hormone. This allows the cells to better respond to the increased hormone levels to maintain homeostasis.
Can you change your DNA with HRT?
Hormone replacement therapy (HRT) can have an impact on gene expression and certain biological markers, but it does not directly change the underlying DNA sequence in your cells. HRT works by influencing how genes are expressed rather than altering the actual genetic code.
Does DNA have cells?
no. Cells have DNA not the other way around
How is the DNA in your brain cells different from the DNA in your heart cells?
They use different DNA codes
