Answer:
true
Explanation:
hope this helps
stay safe
brainliest is appreciated i only need two more to level up please help:))))
because they are both eukaryotic cells
Answer:
2
Explanation:
DNA is tightly packed up to fit in the nucleus of every cell. As shown in the animation, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin
Answer:
density-dependent
Explanation:
limiting factors cause a population's per capita growth rate to change—typically, to drop—with increasing population density. one example is competition for limited food among members of a population. whereas, density-independent factors affect per capita growth rate independent of population density. examples include natural disasters like forest fires.
Answer:
Transcriptional regulators function to regulate the expression of different genes and also to affect the expression of other transcriptional regulators, thereby the combination of a few transcriptional regulators is sufficient to modulate gene expression patterns
Explanation:
Transcriptional regulators are able to control gene expression by binding to cis-regulatory elements on the genome. For example, in plants, MADS-box proteins are transcriptional regulators that contain an evolutionary conserved DNA-binding domain (i.e., MADS-box domain) which regulate simultaneously the expression of many different genes by binding to a conserved DNA motif called CArG box [CC(A/T)6GG] located in the promoter region of many genes expressed at specific stages of plant development. Within the cell, transcription regulators function not only by controlling the expression of different genes but also by affecting each other's activity, thereby creating different combinations where the expression of a limited number of transcription regulators is sufficient enough to regulate gene expression patterns.
