Answer:
Explanation:
Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages. That's because all cells are surrounded by a structure called the cell membrane — which, much like the walls of a house, serves as a clear boundary between the cell's internal and external environments.
It gets absorbed by hair like structures in small intestine which is called villi. They are connected by blood vessels which transport the nutrients around the body.
The correct answer is: B) decreased chromatin condensation
Histone modifications which include phosphorylation, methylation, acetylation and their reverse processes are post-translational modifications that can regulate gene expression. Their effect depends on the amino acid (protein) that is modified, and the combination of the other modifications.
These modifications regulate gene expression by organizing the genome into active form-euchromatin, where DNA is accessible for transcription, or inactive-heterochromatin, where DNA is less accessible for transcription.
The question is incomplete as it misses the options which are:
Cancer cells do not exhibit density dependent inhibition
Cancer cells do not require growth factors
Cancer cells do not exhibit anchorage dependence
Cancer cells ignore typical cell cycle checkpoints
Answer:
The correct answer will be option- Cancer cells do not exhibit anchorage dependence
Explanation:
A cell becomes tumour forming cell or cancerous cell when the cell undergoes some mutation in the DNA which causes uncontrolled cell division without differentiation.
As a result of the mutation, these cancerous cells show various properties which are present in the normal cells nut absent in cancerous cells like the cancerous cells lack the anchorage dependence.
Anchorage dependence is the property of the cells or the group of cells in which the cells maintain their adherence to the other layer of cells to communicate with each other.
Thus, the cancerous cells lack the anchorage dependence
