What effect could a mutation in mRNA have on the production of proteins​

Biology
1 answer:
mote1985 [20]3 years ago
8 0

Answer:

The effect on proteins depends on the type of mutation. Mutations in the mRNA could lead to alterations in the sequence of amino acids in the protein. These alterations could be silent or they can also lead to severe genetic abnormalities.

Explanation:

Point Mutation:

A point mutation in the DNA or RNA alters a single nucleotide base in the DNA sequence. Point mutations are of three types:

  1. Substitution: When a base is substituted for another. This has further 3 types:
  • Missense mutation:

A mutation that substitutes one base for another in such a way that the new sequence forms a new codon that is not a stop codon. For example, if the nucleotide sequence changes from AAG to AGG, the amino acid arginine will be produced instead of lysine.

  • Nonsense mutation

Nonsense mutation substitutes a codon for an amino acid with a stop codon. This kind of mutation produces a truncated or incomplete protein that is nonfunctional.

  • Silent mutation

A mutation that alters the genetic code in such a way that another codon for the same amino acid is produced, rendering no difference to the protein.

   2. Insertion: involves the insertion of a new base in the nucleotide sequence.

    3. Deletion: Involves the deletion of a base from the DNA sequence.

Point mutations, particularly, insertions, deletions and missense mutations can result in truncated or nonfunctional proteins that are unable to perform cellular functions. Cystic fibrosis and sickle cell anemia are prime examples of disorders caused by point mutations.

This type of membrane transport moves substances against the concentration gradient from an area of low concentration to an area
sashaice [31]

<u>Answer</u>:- Active transport

<u>Explanation</u>:-

There are two types of membrane transports

1. Passive transport - this type of transport occurs without the input of any energy and the molecules move along the concentration gradients that is from <em>high concetration to low concentration.</em>

2. Active transport- this type of transport takes place to move the molecules against the concentration gradient that is from <em>low concentration to high concentration.</em>

<em>The active transport is of two types:</em>

1. <em>Primary active transport-</em> in this type of transport <em>ATP</em> is used as an energy source to move the substances against the concentration gradient.

2.<em>Secondary active transport</em> - in this type of transport the gradient formed by the active transport is utilized and it involves the movement of 2 substances at a time aross the membrane. That is the movement of one molecule is coupled to another.


  • The membrane proteins that are associated with active transport are called as <em>carrier proteins</em>. These proteins have a binding site for the molecules that they transport. Once they bind to the specific molecules, a conformation change is induced and this leads to the transport of the molecule across the membrane.

So, the <em>active transport is basically responsible for utilizing the energy from ATP and carrier proteins to move the substances across the membrane against their concentration gradient i.e. from low concentration to high concentration.</em>

An enzyme in a cell became dysfunctional because of an alteration. As a result, the DNA strands would not separate to begin the
yanalaym [24]

Answer:

C. Helicases

Explanation:

Helicases to be termed as enzymes that is blind and contains acid i.e. remodel nucleic or have protein i.e. nucleic acid. It is important as the time of DNA replication as it divided the DNA i.e. double stranded into one single standard that permits each and every strand for copied it

Also it cracks the bonds i.e. hydrogen that lies between the two strands this could create a replication fork.

Therefore in the given case, the helicases is affected

Which DNA fingering technique examines the length variation of DNA repeat sequences in human DNA?
DiKsa [7]

Answer: The question is incorrect, below is the correct question

Which DNA FINGERPRINTING technique examines the length variation of DNA repeat sequences in human DNA?

The correct answer to the question is option D

mtDNA (mitochondrial DNA) analysis

Explanation: DNA fingerprinting technique is a laboratory technique used by geneticists.it entails placing of DNA samples into wells,these wells are then placed in a slab of gels and thereafter passing a current through the gel.This is done to ascertain the uniqueness of a DNA pattern and thus be able to differentiate people of same species.

There are several methods of DNA fingerprinting as outlined in the options given with the question.

In mtDNA (mitochondrial DNA) analysis,The Genetic samples are extracted from the biological materials, these samples extracted are total genomic DNA like hair,tooth or samples of blood, Several copies of these genomic DNA are then produced using a polymerase chain reaction and flanking primers inorder to examines the length variation of DNA repeat sequences in human DNA.
