Transcription chain elongation is thought to generate ____ supercoils ahead of the transcription bubble and _____ supercoils beh
frosja888 [35]

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.

Please Help. Compare the energy input and output for nuclear fission and nuclear fusion.
Andrew [12]

Nuclear fusion and nuclear fission are two different types of energy-releasing reactions in which energy is released from high-powered atomic bonds between the particles within the nucleus. The main difference between these two processes is that fission is the splitting of an atom into two or more smaller ones while fusion is the fusing of two or more smaller atoms into a larger one. Comparison chart Embed this chart Nuclear Fission, Nuclear Fission is the splitting of a large atom into two or more smaller ones. Fusion is the fusing of two or more lighter atoms into a larger one. Natural occurrence of the process: Fission reaction does not normally occur in nature. Fusion occurs in stars, such as the sun. Byproducts of the reaction: Fission produces many highly radioactive particles. Few radioactive particles are produced by fusion reaction, but if a fission "trigger" is used, radioactive particles will result from that. Conditions: Critical mass of the substance and high-speed neutrons are required. High density, high temperature environment is

According to the article, why might Indians rationally choose not to eat cow even during times of starvation?
ludmilkaskok [199]

Answer:

Many Indians believe in Hinduism, which preaches that cows are sacred. They might choose not to eat cow even during times of starvation because they are afraid of the consequences that come in the afterlife. Because cows are sacred, Indians believe that eating them might incur a net negative benefit when considering the afterlife.

Are involuntary muscles striated?
alukav5142 [94]
<span>No.The involuntary muscles of the muscular system are not striated or furrowed.

</span>
<span><span>These muscles that are not striated are very smooth to the sight which is why they are also called Smooth muscles.</span> Involuntary muscles are not striated. Even among the striated muscles that are voluntary, the heart which is also a muscle, is involuntary.
On the other hand the striated muscles, which are voluntary are highly fibrous and their primary function is to move the body voluntarily, and producing heat as a result of this muscle action. </span>
