Transcriptionally inactive regions of the genome are typically heavily methylated. True or false?

The answer is true.

DNA methylation is a process by which methyl groups are added to the DNA, more precisely to its nucleotides adenine or cytosine (they are methylated) via enzymes called DNA methyltransferases. This process as a result can change the activity of a DNA. For example, if DNA of gene promoter is methylated gene transcription is repressed. The opposite process is DNA demethylation.

So, DNA methylation is an epigenetic mechanism meaning that gene activity can be changed and inherited that way, but the sequence  of DNA remains the same.

-DOES have a Nucleus

-More Complex

-Specialized to do certain things

How are the law of independent assortment and the law of segregation different?
san4es73 [151]
Hi there!

The law of independent assortment says that the traits are randomly selected, there is no pattern to how they are sorted. The law of segregation says that the traits are divided between each gamete, using a pattern to sort them.

Hope this helps!! :)

you are a molecule of carbon choose a starting point in the carbon cycle and describe the process you would go through to move t
Dmitriy789 [7]

Answer:

The carbon cycle refers to the procedure in which the atoms of the carbon are recycled again and again on Earth. Carbon recycling occurs within the biosphere of the Earth and between the nonliving environment and living things.  

In case if I were a carbon, then I would have originated from fossil fuels and left the ground, through the process of photosynthesis I would have entered the trees, I would have consumed by animals, even I would have released from some of the trees or plants that dies, I would have also released from animals by the process of decomposition after their demise, and animals can even breathe me in out by the process of respiration.
