I think it’s diffusion but I’m not 100% positive
Answer:
The procedure by which the developing cartilage systematically gets substituted by the bone to produce the growing skeleton is termed as endochondral ossification. The columns of chondrocytes are after that get invaded by the metaphyseal blood vessels, and on the residual columns of the calcified cartilage the formation of bone takes place.
The following are the essential steps in the procedure of endochondral ossification:
1. The chondrocytes get enlarged and the enveloping matrix starts to calcify.
2. The enlarged chondrocytes die.
3. The growth of the blood vessels takes place surrounding the edges of the cartilage.
4. The perichondrial cells turn into osteoblasts and generate a superficial bone layer.
5. The osteoblasts substitute the calcified cartilage with the spongy bone.
Answer:
D) Silent mutation on second codon, third amino acid changed from ILE to ASN.
Explanation:
Silent mutations are usually point mutation where you change one nucleotide. Since, the nucleotide changed is the third position, it does not affect the protein being manufactured (it will still put the amino acid Ala) [look up the codon redundancy on youtub.e to understand how awesome nature is!]
On the other hand, the other mutation introduced is Missense mutation where a different Amino acid is added due to change in codon (goes from ILE to ASN).
