Iteru [2.4K]
The answer is cancer.
Cancer is an uncontrolled division of cells. The regulation of cell cycle is necessary for normal cell division. The first phase of the cell cycle is the G1 phase. If the G1 phase is affected, mistakes in this process lead to the uncontrolled division of cells called cancer.

. the negatively charged part of an atom
Slav-nsk [51]

Answer:

Electrons are the negatively charged particles of an atom. Together, all of the electrons of an atom create a negative charge that balances the positive charge of the protons in the atomic nucleus. Electrons are extremely small compared to all of the other parts of the atom. The mass of an electron is almost 1,000 times smaller than the mass of a proton.

During replication, nucleotide bases are added to DNA strands in a ___ direction(s).
Alborosie

Nucleotide bases are added to DNA strands in a 5' to 3' direction.

What is DNA replication?

When a cell divides, DNA copies itself through a process called replication.

  • Generally speaking, DNA replication involves uncoiling the helix, strand separation by rupturing the hydrogen bonds between the complementary strands, and synthesis of two new strands through complimentary base pairing.
  • The origin of replication, which is a precise location in the DNA, is where replication starts.
  • From the point of origin, DNA replication is bidirectional.
  • The two parent DNA strands unwind and split apart at the origin of replication to generate two "Y-shaped" replication forks in order to start DNA replication.
  • These unwinding enzymes are known as DNA helicases.
  • The real location of DNA copying is at these replication forks.
  • Proteins that destabilize helices bind to the single-stranded areas to prevent the two strands from rejoining.
  • To reduce stress on the helical molecule during replication, enzymes known as topoisomerases cause breaks in the DNA and then reunite them.
  • The hydrogen bonding of free DNA nucleotides with those on each parent strand results in the formation of new complementary strands as the strands continue to unwind and split in both directions around the entire DNA molecule.
  • The new nucleotides are joined by DNA polymerases using phosphodiester bonds as they align themselves opposite each parent strand using hydrogen bonds.
  • Deoxynucleotide triphosphates, which are made up of a nitrogenous base called deoxyribose and three phosphates, are the actual nucleotides that are aligning through complementary base pairing.
  • Two of the phosphates are withdrawn to provide energy for bonding as the phosphodiester bond forms between the 3' OH of the previous nucleotide in the DNA strand and the 5' phosphate group of the next nucleotide.
  • In the end, two identical DNA molecules are created when each parent strand acts as a template for the synthesis of a complementary copy of itself.

Hence, nucleotide bases are added to DNA strands in a 5' to 3' direction.

Coat color in mice is incompletely dominant. Yellow and white-colored mice are homozygous, while cream-colored mice are heterozy
Lera25 [3.4K]
Since it's incomplete dominance we know that all the traits are of course dominant.

That in mind we know that anything heterozygous will have two different traits, making the cream colored mice have a punnet square somewhat like this:

         W       Y
W    WW    WY

Y     WY     YY  

Referring back to the yellow and white mice being homozygous (two of the same traits) we can gather from this punnet square the ratios for both.

WC = Cream colored = 50%
WW = White = 25%
YY = Yellow = 25%
