Science isn't just gathering factual information and data, it's a body of knowledge. It's a way of thinking about problems, and how to solve them. Science shapes everything in our world since everything revolves around natural rules.
It's thanks to computer <em>science </em>that you're able to be on this site right now. It's thanks to <em>science </em>as a whole that we have any of the technology we have today, and the cures for the many once <em>deadly </em>diseases. So, if you want to know how science shapes our world... Just look around you. =)
Dioxy-ribo nucleic acid/dna
Answer:
a. positive; negative
Explanation:
Transcription is the process of forming an RNA molecule from a DNA template molecule. In this process, the strands of DNA separate and one serves as a template for RNA, while the other is inactive. At the end of the transcript, the tapes that have been split back together again.
The transcription process is divided into three steps: initiation, stretching and termination
During the stretching phase, transcription chain elongation occurs. In this phase the enzyme called RNA polymerase starts to move through the DNA molecule, unwinding its helix and producing an increasingly lengthened RNA molecule. The already transcribed DNA is rewound almost immediately, recomposing its double helix. This process is called the elongation phase.
During this process, it is believed that positive supercoils are generated ahead of the transcription bubble and and the negative supercoils behind it.
In adults, stem cells remain undifferentiated until they are needed to repair or replace other cells. Stem cells can produce cells that are identical to themselves.
You see, passive transport needs no energy. So that being said, it moves from areas with high concentration to areas with low concentration.
Hope that helps!
