Answer:
Mitochondrial DNA is circular, so it doesn't shorten when it replicates unlike the rest.

Answer/ Explanation:
The original DNA sequence has a point mutation changing a G to a T. The resulting mRNA produced is always complementary to the DNA from which it is synthesised, so the original mRNA sequence has a T, whereas the mutated mRNA has a U. The tRNA is complementary to the mRNA, so the original has a G, and the mutated has a T.

This is a point mutation called a substitution. This does not affect the entire sequence of the protein, because the mutation is "in frame" meaning the mRNA sequence is still read in the same way by the protein producing machinery. However, it does change the 5th codon from UGC to UGU. If we look up the genetic code, we can see that both of these codons code for cysteine, so there will be no change in the amino acid sequence of the protein
Answer:
It's True!!!!!!!!!!!!!!!!!!
The process of having to apply a tourniquet in a person’s
leg due to injury and with continuous bleeding in order to stop it is called
hemostasis. This process, the hemostasis, is a process of having to stop the
flow of blood which is important in scenarios like this, in order for the
patient to prevent of having to lose more blood.
