1. You have set up a cell-free transcription system in a test tube. By mixing DNA, RNA polymerase, sigma factors, ribonucleotides and other essential substances you are able to make mRNAs identical to those made under a variety of conditions in the cells from which these components were isolated. What would happen if you were able to remove the sigma factor first added to the tube and replace it with another sigma factor
Answers
Answer:
Different messenger RNAs (mRNAs) would have been produced
Explanation:
Sigma factors are protein subunits that form bacterial RNA polymerases and they are responsible to initiate RNA synthesis. The number of sigma factors is variable between different bacterial species. For example, Escherichia coli contains seven sigma factors, while Bacillus subtilis has at least 17 sigma factors, which control the transcription of different genes. These factors determine the specificity of the RNA polymerase to the target gene promoter regions and then control transcription initiation.

If mRNA had the codon GUA, what amino acid does that code for?
Answers
Answer:
Valine
Explanation:
This question is describing the process of translation, which is the second stage of protein synthesis. Translation is the process whereby mRNA sequence is used as a template to produce an amino acid sequence or protein.
The mRNA sequence is read in a group of three nucleotides called CODON. Each codon specifies an amino acid. According to this question, using the genetic code provided for us in a tabular form in this question, a mRNA codon as follows: GUA will code for VALINE amino acid.

Answer:
The average speed of train is 133.33km/hr.
Explanation:
We know that
Average speed= [tex]\frac{Total distance}{Total time}[/tex]
So,
average sped of the train = [tex]\frac{800 Km}{6 hr}[/tex]

What is one of the biomolecules for which nitrogen is needed (hint: they help build muscles)?
Answers
One of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.
What is the significance of the nitrogen in the protein?Proteins play many important roles in the body, including building and repairing tissues, and nitrogen is a critical component of proteins, as it is incorporated into the molecule as a part of the amino acids. Without nitrogen, proteins would not be able to form and perform their many important functions so a diet that is rich in protein is important for athletes and bodybuilders to build and repair muscle tissue.
As a result, of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.

Which statement about how geologists study the ages of rock layers is true?
The law of superposition means that older rocks are on top.
Geologists can find the exact age of a rock by looking at its relative position.
The principle of original horizontality provides the basis for the law of superposition.
Relative age can be determined by using the concept of unconformity.
Answers
Answer: The principle of original horizontality provides the basis for the law of superposition.
Explanation:
The law of superposition in geology suggests that the rocks or sediments which are newly formed due to erosion and sedimentation of the original rocks lie above the old material. This law is supported by the principle of original horizontality according to which the newly formed sediments suspend horizontally in the layers of rocks and sediments under the effect of gravity. Thus an horizontal strata distinguishes the old and the new material.

The color of an object that humans see is actually the ______ of light reflected off the object
Please answer !!!
Answers
I’m pretty sure
An object's color is really determined by the light wavelengths that are reflected while all other wavelengths are absorbed.
What is light reflection?In this context, color refers to the various light wavelengths in the visible light spectrum that are seen by human eyes.
An item is viewed as black if it absorbs all the hues of white light, as demonstrated in the following illustration. A white item will evenly reflect all shades of white light.
The light waves that an item reflects determine its "color." This is governed by the configuration of electrons in the atoms of that substance, which, in accordance with complex quantum principles, will absorb and reemit photons of a certain energy.
Therefore, an object that humans see is actually the wavelengths of light reflected off the object.

An ion of aluminum has a charge of 3+. The ion contains 10 electrons. How many protons does a neutral atom of aluminum possess?
Answers
Answer:
13 protons
Explanation:
Aluminum, which has a symbol of Al, is an element in group 3 of the periodic table. It has a mass number of 27. Since the number of electrons and protons in a neutral atom are the same, a neutral/uncharged atom of aluminum contains 13 electrons, 13 protons and 14 neutrons. Note: Mass number = no. of protons + no. of electrons.
However, according to this question, an ion of aluminum has a charge of 3+, this means that an atom of aluminum has lost 3 electrons i.e. 13 electrons - 3 electrons = 10 electrons. Hence, aluminum atom with charge +3 will have 10 electrons. This doesn't change the fact that aluminum atom in a neutral state possesses 13 protons.

At Weeks Bay there was a population of 200 alligators. In May of 2006 a new species of catfish was released into the Mississippi. These catfish reproduce very fast and soon become a rich food source for the alligator population. This provides the alligators with the energy needed for more successful reproduction. The following summer of 2007, 100 babies were born and a total of 40 gators died that year. However, the next year in early 2008 there was a terrible drought, causing 100 alligators to die.
