While looking at a cell under a microscope, a scientist is able to see a biological molecule. This molecule is a nucleic acid wi

th double strands and contains the nitrogenous bases adenine, thymine, cytosine, and guanine. Based on this information, what conclusion can the scientist draw regarding this nucleic acid?

He/she would be able to conclude that due to the lack of uracil and presence of double strands that the molecule is DNA and not RNA.

Answer:

It is a DNA molecule (deoxyribonucleic acid).

Explanation:

There are only two types of nucleic acids in nature based on their structure and composition which are mentioned as under:

(1) DNA (Deoxyribonucleic acid)

(2) RNA (Ribonucleic acid)

A DNA molecule is characterized by double helix in which two strands which are anti parallel to each other are joined together with the help of interactions like hydrogen bonds which exist between the nitrogenous bases of these two strands. For example, adenine of one strand is joined with thymine of another strand by 2 hydrogen bonds (A=T) while cytosine of one strand is joined with guanine of another strand by 3 hydrogen bonds (C≡G). In contrast to this, an RNA molecule is single stranded therefore no such interactions exist in the RNA molecule.

Also, an RNA molecule does not have thiamine as nitrogenous base in it, instead of thiamine it has uracil.

Based on the above mentioned facts we can easily conclude that this nucleic acid is DNA.

Which term can be used to describe the organizational level of the brain in the human body?
Minchanka [31]

Organ is the term that can be used to describe the organizational level of the brain in the human body.

When we speak of the levels of organization, we refer to the possible divisions or stratifications in which it is possible to study the human body.

In this area, an organ is an associated set of tissues that share the same structure and function.

The scale of biological complexity places organs above tissues and below systems.

The human brain is a main and complex organ that is part of the nervous system, it controls the vital functions of the human body.

It is the organ in charge of controlling and coordinating all the movements we make and processing sensory information.

As an organ system at organizational level it works together with the spinal cord forming the central nervous system.

Therefore, we can conclude that organ is the term that can be used to describe the organizational level of the brain in the human body.

In a separate maddyase experiment using (Et)-10nM, the reaction velocity is measured as 3uMS. What is the substrate concentratio
Vinvika [58]

Answer: hello your question has some missing data attached below is the missing data

Applying the Michaelis-Menten Equation

An enzyme is found that catalyzes the reaction X ⇋ Y Researchers find that kcat for this enzyme is 600s^-1 and carry out several additional experiments.

answer :

substrate concentration [ x ] = 10⁻⁵ M

Explanation:

Given data:

[Et ] = 10 * 10⁻⁹ M ,  

Reaction velocity ( V₀ ) = 3* 10⁻⁶ Ms⁻¹

applying Michaelis-Menten  Equation

= 3* 10⁻⁶ = \frac{600 *10*10^{-9} * (X)  }{10^{-5} + (X) }  ,    

= ( 3 * 10⁻⁶ )( x ) + ( 3 * 10⁻¹¹ ) = ( 6 * 10⁻⁶ ) ( x )

hence the substrate concentration [ x ] = 10⁻⁵ M
