Answer:
n stage 13, all four limb buds are present. In stage 13, the upper limb buds resemble flippers. In stage 23, the upper limb shows well-formed arm, elbow, wrist, and fingers. In stage 23, the lower limb shows well-formed toes, feet, and knees.
Explanation:
When there will be a low salt environment, the jellyfish will increases the intake of water through its surface, because the solvent concentration will be low inside the jellyfish, as compared to the estuary. Thus, it will swell up and may die after bursting, as well. The environment is called as a hypotonic environment. The solute concentration is high inside jelly wish and lower in the estuary, thus, fluid diffusion will occur from fish to water body
The two ways by which we can detect that gene editing have occurred in the bacteria are;
A) WESTERN BLOT; Here,the gene that is edited will not be able to synthesize the protein.With this,if we do western against the already edited protein,no band will eventually appear in the western blot,and this indicates/confers that the gene have been edited.
B) PCR FOLLOWED BY SEQUENCING; IN PCR,there is amplification of the region with the use of flanking end primers that is edited.
However,mean primers will actually be used in a way that one primer is upstream to site of editing and the other primer to the downstream.
From this stage,the PCR product that is amplified will be sent for sequencing,and this sequency result will further confirm if the gene has been edited or not edited.
Restriction enzyme can also be used if the place where the gene has been edited is known.
If actually the gene has been edited,the nucleotide sequence will get changed.Having to choose such enzyme that cut only one's wide type wild type DNA but not actually gene that is edited,the result will further be compared inorder to confirm whether the gene has been edited or not.
Proteins that are functionally less important for the survival of an organism generally evolve faster than more important proteins.
Proteins serve as the building blocks for all of life's essential processes. The proteins evolve along with the genes that create them, adding new functionality or features that may potentially result in the development of new species.
The mutation of amino acid-coding nucleotides and the stabilization of novel variations in the population are the two phases required for protein evolution.
The stability of a protein's folded structure, how well it prevents aggregation, and how well it is chaperoned all affect how quickly it evolves. According to the studies, the degree of a protein's expression has a greater influence on its evolutionary rate than does the protein's functional significance.
