Which of the statements about the relationship between DNA technology and genetic diversity is accurate? a.DNA technology can re
Airida [17]

Correct answer: D). DNA technology can increase genetic diversity by producing more variant alleles.

The genetic diversity can be increased by the mutation that creates new alleles in the population. The recombinant DNA technology enables the joining of DNA from the two or more than two sources that allow changing the genetic composition of the living organism. The genetic diversity helps the population to adapt to the changing environment.

Hence, the correct answer would be option D.

Is the heme molecule attached to hemoglobin during the primary level or tertiary level of organization?
djyliett [7]

Answer:

Tertiary.

Explanation:

Primary structure of proteins refers to the order of amino acids that make up the protein. The heme is an nonprotein non-amino acid, so it is not involved at this stage.

Tertiary structure of proteins is the overall 3-D folding of the protein (it comes after secondary, which involves folding into a repeated pattern). The heme bonds to its correct position on the hemoglobin during this stage and helps in correct folding.

How many different DNA sequences of 32 bases can you have if there is unlimited availability of all bases
Annette [7]

we have 4 different bases: Adenine(A) thymine(T) cytosine(C) and guanine(G)

We have combinations 32 taken 4

written as 32C4=32!/4!(32-4)!=32!/4!*28!=29*30*31*32/24=35960
