The process of transcription will b stopped. Sigma factors are responsible for determining the specificity of promoter-DNA binding by polymerase and control how efficiently RNA synthesis (transcription) is initiated. High temperatures probably interfere with the structure of the sigma protein and change the conformation of the active site that binds to the rna polymerase.

Answer:

Their DNA is organized into chromosomes

Explanation:

The only possible answer from the options provided in the comments is that the DNA is organized into chromosomes. The other options are all false. Animal cells do not contain a cell wall, that is specific to plant cells and some bacteria. Animal cells do not have a single loop that contains all of their DNA, that is a feature of bacterial cells. Eukaryotic cells do have membrane bound nuclei, this is in contrast to prokaryotic cells.

However, eukaryotic DNA is organized into chromosomes

The kinetic energy of a ball with a mass of 0.5 kg and a velocity of 10 m/s isJ.
sergiy2304 [10]
My answer -

The formula for calculating kinetic  energy (KE) is KE = 0.5 x mv2. Here m stands for mass, the measure of how much matter is in an object, and v<span> stands for velocity of the object, or the rate at which the object changes its position.
Hope i helped

In a good experimental design, the part of the experiment that is intentionally changed is the
Vika [28.1K]

Constants never change.

Controls typically don't change or they are done by standard means

(like in an experiment where you water plants with sodas, the plant you use water with is the control)

Dependent variables are the outcome of the experiment. This is the result of changing something.

Independent variables are what you are testing. A independent variable is something that is  intentionally altered.

easy way to remember it is that dependent variables depend on what other variables are. so you cant change a dependent variable, but you can change the other variables.
