How an mRNA is synthesized using a gene

Answers

The nucleus uses the nucleotide sequence of DNA as a template to make mRNA. The enzyme RNA polymerase II catalyzes this activity, which requires nucleotide triphosphates as substrates. Transcription is the process of producing mRNA from DNA, and it takes place in the nucleus. The DNA of a gene serves as a template for complementary base-pairing during transcription, and an enzyme known as RNA polymerase II catalyzes the synthesis of a pre-mRNA molecule, which is then processed to generate mature mRNA.

Answers

Answer:

I believe the  correct answer is C. mRnA translation.

Explanation:

Because the gene expression is controlled on two levels. First, transcription is controlled by limiting the amount of mRNA that is produced from a particular gene. The second level of control is through post-transcriptional events that regulate the translation of mRNA into proteins.

Describe how a nonpolar to polar R group substitution changes the structure and function of a protein.

Answers

A nonpolar to polar R group substitution changes the structure and function of a protein because polar structure can dissolved polar and non-polar can dissolve non-polar.

Why change of nonpolar to polar affect structure and function of protein?

The change of nonpolar to polar leads to change in structure and function of protein because the arrangements of atoms are different which leads to change of function as well.

So we can conclude that nonpolar to polar changes the structure and function of a protein because polar structure can dissolved polar and non-polar can dissolve non-polar.

1. Conduct research about why molecular-level structure is important in the
functioning of designed materials. You should research at least two examples. Then
communicate this scientific and technical information using written text and
graphics. (5 points)
A) What is the difference between bonding forces holding compounds together and
other attractive forces? What types of chemical bonding and intermolecular forces do
the materials have?
B) Predict the general properties of your materials based on the types of bonds they
have. Properties include melting point, boiling point and conductivity
C) analyze your materials specific physical and chemical properties. properties include color, density, viscosity, buoyancy, boiling point freezing point, conductivity, and reactivity.
D) designed materials need to meet certain requirements. when designing new products why is it important to study the properties of the materials?

Answers

Molecular-level structure is vital in the design and use of materials mostly at the macroscopic-stage. The structure of a molecule is known to influence how it interacts with other molecules.

Note that Attractive and repulsive forces are the ones that plays a vital role in the total properties of matter seen on the scale.

Molecular structure is known to be the one that helps us to know more about Nature's intricate design methods and blueprints. When we know the blueprints and basic materials, we can then try to mimic her essential products that are cost effective and the ones that has less harmful environmental effects.

What is the Difference between bonding forces and intermolecular forces ?

The Difference between bonding forces and intermolecular forces is that Intermolecular forces are known to be forces that are said to hold two or more molecules as one while a chemical bond is known to be an attractive force that exist between two or more atoms.

The types of chemical bonding and intermolecular forces that  materials have are:

For Chemical bonds they are:
