Answer:
The correct answer is option E) "The presence of one or more introns".
Explanation:
Introns are non coding sequences located within genetic sequences that are removed during RNA maturation by a process known as RNA splicing. A gene that has 2000 nucleotide pairs but is translated into a mRNA molecule with 1200 nucleotides most likely have one or more introns that in conjunction are of 800 nucleotides in size. Once the intros are removed from the mRNA molecule the coding sequence is ready to be translated into a protein.
Normal development in tests requires a temperature. cremaster muscle contract or relax to move testes toward or away from the body or to maintain the acceptable temperature for testicular.
The body temperature regulation is controlled by the autonomic nervous system under the guidance of medulla oblongata which is in the brain system.
A karyotype is a person's whole set of chromosomes. The term also refers to a laboratory-produced photograph of someone's chromosomes isolated from a character mobile and organized in numerical order. A karyotype can be used to search for abnormalities in chromosome quantity or structure
karyotypes can reason bodily sperm issues, many guys with Karyotype issues together with balanced translocations have normal searching sperm that convey DNA troubles that purpose infertility and miscarriages for them and their partner.
Karyotypes can reveal changes in chromosome range associated with aneuploid situations, inclusive of trisomy 21 (Down syndrome). careful evaluation of karyotypes also can display more diffused structural modifications, which include chromosomal deletions, duplications, translocations, or inversions.
