Answer:
Polymerase chain reaction (PCR)
Explanation:
Polymerase chain reaction (PCR) is a method by which a target DNA fragment is amplified to produce millions of copies. In PCR, the Taq polymerase enzyme uses nucleotides and primers to replicate a small DNA segment <em>in vitro</em> and produces two DNA molecules. The newly formed DNA molecules are denatured by heating to facilitate their replication to produce four double-stranded DNA molecules. In this way, the number of DNA molecules is doubled in each cycle. Therefore, the small amount of DNA obtained from the minuscule spot of blood on a murder suspect’s shirt can be amplified using PCR.
So, I haven't really seen this question I think but in my class when we had science before we learned about Kinetic and Potential energy. So, my most best answer I can give is most likely Kinetic Energy. Sorry if it's wrong. Hope this helps! ^^
The answer is A.only autotrophs can convert solar energy into chemical energy.
Answer:
The correct answer will be option-D.
Explanation:
During the electron transport chain, an electrochemical gradient is established due to the movement of electrons.
The high number of protons gets accumulated in the intermembrane space of the mitochondria whereas less number of protons present in the matrix.
The protons are pushed from the outer membrane to matrix through ATP synthase where the movement of ATP causes synthase to spin and bind ADP and Pi to produce ATP.
Thus, option-D is the correct answer.
If a gene is found only on the X chromosome and not the Y chromosome, it is
said to be a sex-linked trait. Because the
gene controlling the trait is located on the sex chromosome, sex linkage is
linked to the gender of the individual. Usually such genes are found on the
X chromosome. The Y chromosome is thus missing such genes (See Diagram above.).
The result is that females will have two copies of the sex-linked gene while
males will only have one copy of this gene. If the gene is recessive, then males
only need one such recessive gene to have a sex-linked trait rather than the
customary two recessive genes for traits that are not sex-linked. This is why
males exhibit some traits more frequently than females.
