Generally nonsense is much much worse. It creates a premature stop code which can throw off the entire chain of codons and makes things much much worse. A good way to remember this is that the nonsense mutations make the codons not make sense.
Answer:
Cellular specialisation is the process by which an initial undifferentiated cell, gets specialized (attains a structure and function characteristic of a given cell type). In this case, the embryonic stem cells, undergo specialisation to give the many different cells and tissues of the body. Without cellular specialisation during embryo development, we wouldnt have all these varying tissue types fine-tuned to their functions.
Answer:
They differ in sex chromosomes.
Explanation:
There are two types of chromosomes; autosomes(22 pairs) and sex chromosomes(1 pair).
While all the autosomes are same in the case of both male and female humans, sex chromosomes differ.
Human male has one X and one Y chromosome, while human female has two X chromosomes. Y is roughly shorter by half than the X chromosome.
Cardiac muscle tissue or myocardium
Answer:
The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.
