Answer:
p53 helps the cells from passing on mutations that lead to DNA damage. Hence, it is known as the guardian angel of the cell as it helps fight against cancer. However, if p53 becomes defective or missing, then the mutations will lead to cancer.
Mutations in the p53 can also cause the tumor-suppressing genes to convert into tumor causing genes. Hence, mutations in such kind of genes can be very harmful for the body.
I believe the answer is C. Nucleus, Cell Wall, Cell Membrane
Answer:
DNA replication is the process in which the DNA is copied and it occurs during synthesis phase of the eukaryotic cell cycle. It begins with an enzyme breaking the bonds between complementary bases in DNA which exposes the bases inside the molecules so they can be read by another enzyme and used to build two new DNA strands with complementary bases.
Explanation:
The original strand is: TAGCGTT
ATCGCAA
The Mutated strand is: TGGCGTT
ATCGCAA
<em>The replicated strand is: GAATCAC</em>
<em> CTTAGTG</em>
Answer:
The correct option is number 2. NADH is not product of light reactions of photosynthesis.
Explanation:
The light energy from the sun is captured by the pigmented molecule, chlorophyll, of the plants. This light energy is converted into chemical energy by a serious of light-dependent reactions. The main products of light-dependent reactions are the energy molecule ATP and NADPH. Oxygen is released as a by-product during photosynthesis. Hence, all the option 1,3 and 4 are produced during the light reactions except for option 2 i.e NADH.
The integumentary system is the skin. Skin protects the inner organs from Bactria. Essentially the skin is a wall protecting against the outside world. It doesn't really release anything but is just there for protection.
Hope this helped!
