Answer:
The exons may be defined as the coding region of the RNA that codes for the particular amino acid. The introns are the non coding region of RNA and must be removed in the final RNA product.
Exon shuffling result in the formation of new gene. The alteration of the exon and intron structure leads to the new gene function in evolution. The genes that are favored and conserved in the evolution perform new gene function. The genes that are selected against are deleted during the evolution.
Answer:
sexual reproduction involves to organisms
Explanation:
Note about the question:
In the GIZMO program, you will be provided with 46 chromosomes that are not paired nor in order (box superior-right). According to the chromosome image shown below, you need to look for the correct chromosomes, pair them with their homologous, and place them in their correct spot to complete the karyotype.
Answer:
- Subject B sex: Female
- Justification: The last pair of chromosomes are equally large, meaning that they are two X chromosomes (XX).
Explanation:
<em>Note: You will find the complete karyotype in the attached files.</em>
A human cell has 46 chromosomes or 23 pairs of homologous chromosomes. 22 of them are somatic chromosomes or not-sex chromosomes. The last pair, number 23, is the only sex pair.
To know if an individual is a male or a female, you just need to see the last pair of chromosomes. Pair 23 is the sex pair.
- Male: The pair is formed of a short chromosome (which corresponds to Y from the male parent) and a large chromosome (which corresponds to X from the female parent)---> XY
- Female: The pair is formed of two equally large chromosomes. Each of them corresponds to X, one from the male parent and the other from the female parent). ----> XX
The upheaval was caused by widespread discontent with the French monarchy and the poor economic policies of King Louis XVI, who met his death by guillotine, as did his wife Marie Antoinette.
migratory bird is a bird that travels from one place to another at regular times often over long distances. ... Most native birdspecies (birds naturally occurring in the United States) belong to a protected family and are therefore protected by theMigratory Bird Treaty Act.
