It should be A. It is universal among all life on Earth.
Regular human body cells or somatic cells have a total of 46 chromosomes. Therefore, because of meiosis, sperm cells, which are gametes or sex cells must contain 1/2 of the number of total chromosomes found within a somatic cell, to make sure that the chromosome number within an organism is maintained, this would be 23 in this case.
Answer:
true
Explanation:i just know trust me
Answer:
B. positive
Explanation:
Histones are proteins that bind to the DNA in order to form highly compacted structures named nucleosomes, the basic structural units of DNA packaging in eukaryotic genomes. A nucleosome is a segment of DNA wound around an octamer (8) of histones, i.e., two copies each of the histones H2A, H2B, H3, and H4. These histones are positively charged in order to interact with the negatively charged DNA molecule. During transcription, reducing histone positive charge decreases the interaction between DNA and histones in the nucleosomes, thereby opening the chromatin to favor the access of the transcriptional complex and thus facilitates gene expression.
Answer:
I believe that is true
Explanation:
I think it is because i know divergent boundaries are tectonic plates that are moving away from each other which can cause many oceans and split natural wonders.
