Researchers can manipulate the genes of a mouse so that a single gene in a single tissue either produces an inactive protein (a
s2008m [1.1K]

Answer:

1) The genetic changes can lead to a reduction in the capacity of the mice to move glycogen at its branches points and lowers blood glucose levels between meals.

2) Genetic changed can lead to a decrease in the capacity to lower blood glucose due to the knock out of the hexokinase gene leading to elevated levels in the bloodstream.

(c) A knockout of FBPase2 will result in elevated levels of fructose-2,6-bisphosphate in

liver favoring the glycolytic pathway and inhibiting gluconeogenesis by the decrease of fructose 1,6-

bisphosphatase-1 activity

(d) An active FBPase-2 will now favor gluconeogenesis and this inhibits glycolysis. I.e. a decrease in PFK-1 activity while increasing FBPase-1 activity simultaneously.

In which order will free nucleotides add on to a single strand of DNA with the sequence ATTGCA during DNA replication?
AnnZ [28]
The answer is T A A C G T.

Replication is a process in which DNA molecule is copied, and thereby two identical DNA molecules are produced.  Complementarity is achieved through interactions between nucleobases. In the DNA, base complements are adenine - thymine (A-T) and guanine - cytosine (G-C). 

So, free nucleotides will add in the following order <span>T A A C G T:
original strand                 new strand
     A                                       T
     T                                       A
     T                                       A
     G                                      C
     C                                      G
     A                                       T</span>

Describe two examples of ancient and modern organisms that may be related. Use evidence and scientific reasoning to support your
omeli [17]

Two examples of related organisms are dinosaurs/chickens, and the megalodon/the great white shark.

<h3>How have organisms evolved?</h3>

Life emerged on our planet 3.7 billion years ago, and since then organisms have evolved or changed over time this includes:

  • The appearance of more complex organisms, which is the result of natural selection.
  • The diversification of organisms.
  • The extinction or disappearance of species.

This has caused all organisms that exist today to be related to other organisms of the past. Let's examine two examples.

<h3>Dinosaurs and chickens: </h3>

According to scientific research, birds evolved from dinosaurs. Indeed, it has been determined birds started with theropods, which were a specific group of dinosaurs.

This means modern birds including chickens are related to this group of dinosaurs, even if overtime birds have evolved a lot and they might not seem to be very similar to dinosaurs.

<h3>The megalodon and the great white shark:</h3>

These two species of shark likely share a common ancestor and due to this, both species have many similarities such as the shape of their teeth. However, megalodons are extinct, while great white sharks still exist today.
