Many different types of mutations can occur within the body. An individual experiences a mutation that changes a base in
a mRNA strand, but during translation the mRNA strand still creates the same protein. Which type of mutation is
responsible for the change in the mRNA base?

A.silent

B.missense

C.nonsense

D.insertion

Answers

Answer 1

Answer:

A. Silent, The type of mutation responsible for changing a base in the mRNA strand, without changing the coding aminoacid or protein, is called a silent mutation.

Explanation:

In a silent mutation occurs the change of a nitrogenous base in one of the codons that encodes an aminoacid, without changing the aminoacid or altering the structure or function of the protein to be synthesized.

In this type of mutations the change of the base does not mean the change of the aminoacid, because some aminoacids can be coded with more than one codon. In the case of Leucine, the codons that encode it are CUU, CUC, CUG or CUA, so even if a base changes, the final protein will be the correct one.

For the other options:

Missense: the change of the base in the DNA chain implies the change of the codon in the mRNA and of the encoded aminoacid, in that way a structural and functional alteration of the synthesized protein occurs. Nonsense: the change in the nitrogenous base in the DNA leads to the coding of a termination codon, so that the protein is ultimately incomplete. Insertion: in this case there is the addition of more nitrogenous bases to the DNA chain, with respect to the original one.

How did Concorde fly so high?

Concorde fly so high because the higher it flew, the thinner the air was that it encountered. This consequently led to less drag and fuel burn.

Did the Concorde fly in the stratosphere?

Able to cruise at a near-stratospheric altitude of 60,000 feet at 1350 miles per hour, the plane cut travel times on its routes in half. But speed and altitude were not the only factors that made Concorde so remarkable.

Glucose is only a storable form of energy, but ATP can be used and stored.

Answers

The main difference between glucose and ATP is that Glucose is a storable form of energy, while ATP is a usable form of energy.

Glucose is storable form of energy because it can't be used as energy until it can be broken down by mitochondria of the cell while on the other hand, ATP is the usable form of energy which we can get from the break down of glucose molecules. Our cells use ATP as a fuel to do various activities of the cell so we can conclude that in glucose, energy is present in stored form whereas ATP is used as energy in various activities.

protein?
a) The number of amino acids determines the tertiary structure of the protein.
b) The interactions of the different R-groups with other R-groups and with their environment
determine the tertiary structure of the protein.
c) The R-group of the last amino acid that is added to a growing polypeptide chain
determines the next amino acid that is added to the chain.
d) The sequence of the amino acids in the polypeptide chain determines the protein's
primary structure but has no effect on its tertiary structure.

Answers

Answer:

It is B

Explanation:

I had this question on my test last week

The tertiary structure of the protein is determined by the interactions of the different R-groups with other R-groups and with their environment in the protein (Option B).

An R-group (also called variable group) is a side chain that is attached to the α-carbon of the amino acids, the building blocks of proteins.

The linear sequence of amino acids within a protein is the primary structure of proteins.

The second structure of proteins is determined by the pattern of hydrogen bonding in the peptide backbone. The most common secondary structures of the proteins are alpha-helices and beta-sheets.

The protein tertiary structure is the 3D (tridimensional) shape of the protein, which is due to interaction among R groups of amino acids and with their environment.

The most common tertiary structures of the proteins are globular and fibrous structures.

Finally, the quaternary structure of the proteins is determined by the interaction of several protein chains or subunits.

In conclusion, the tertiary structure of the protein is determined by the interactions of the R-groups and with their environment in the protein (Option B is correct).

Which of the following statements tells how facilitated diffusion differs from
simple diffusion?
A. Particles move through cell membranes without the use of energy by cells.
B. Particles tend to move from high concentration to lower concentration.
C. Particles move within channel proteins that pass through cell membranes.
D. Particles tend to move more slowly than they would be expected to move.

Answers

Answer:

I think its C but I am not sure, I hope this helps :)

Explanation:

The statement 'particles move within channel proteins that pass through cell membranes' indicates the reason for which facilitated diffusion differs from simple diffusion (Option C).

Diffusion (both facilitated diffusion and simple diffusion) refers to the movement of substances across biological membranes from an area of high concentration to an area of low concentration.

Facilitated diffusion and simple diffusion are two types of passive transport that do not require energy to move molecules/ions in favor of a concentration gradient.

In facilitated diffusion, specific membrane proteins known as carriers or channels help to the movement of substances in favor of a concentration gradient.

Conversely, in simple diffusion, small molecules (e.g. CO2 and oxygen) freely diffuse across a selectively permeable membrane in favor of a concentration gradient.

In conclusion, the statement 'particles move within channel proteins that pass through cell membranes' indicates the reason for which facilitated diffusion differs from simple diffusion (Option C).
