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.

In hemoglobin Rainier, Tyr 145β is replaced by Cys, which forms a disulfide bond with another Cys residue in the same subunit. T
lions [1.4K]

Answer:

Hemoglobin rainier differ from normal hemoglobin with respect to oxygen affinity.

Explanation:

Hemoglobin is one of the most significant protein of Red Blood Cell containing heme(that contain Fe2+ which is coordinated with four porphyrine rings) and globin protein.

  Hemoglobin exist in two state one is tensed state or deoxy hemoglobin that have less affinity for oxygen, the other state is relaxed state or oxy hemoglobin that has high affinity for oxygen.

              In hemoglobin rainer the formation of new di sulfide bond prevent the formation of ion pairs that normally stabilize the T state as a result T state get unstable and this unstable T state is converted to R state to achieve the stability of hemoglobin structure.

           The R or relaxed state of hemoglobin has high oxygen affinity for oxygen.
