Answer:
DNA damage signaling processes are essential foe regulating the G0 transition within the cell cycle.
Explanation:
Cell cycle is a process which prepares a cell for division.Cell cycle has various phases G0 phase,G1 phase,S phase,G2 phase and M phase.Each phase is specialized for its particular function.
Every phases of a cell cycle is under tight regulation of various proteins and this regulation is very much important to maintain the normal level of principle constituents of a cell.
DNA damage is detected by G1 cyclin CDK protein which transit the cell containing the damaged DNA into the G0 phase or quiescent phase for repair and if the damage cannot be repaired then the cell containing damaged DNA is targeted for destruction by ubiquitin pathway.
Answer:
The correct answer would be -
50% heterozygous red flies and 50% recessive brown eyes flies in offspring
Explanation:
This is given that a species of fly has two traits for the eye red eye which is the dominant trait and can be represented by R and the brown eyes trait which is recessive and represented by r.
Given: heterozygous fly which means have both traits gene but as Red is dominant it will have red eyes mates with recessive brown eye fly.
Rr × rr
gametes: R, r and r, r
then,
R r
r Rr rr
r Rr rr
There is 50 % recessive brown eyes flies in offspring and 50% heterozygous red eys offspring.
Hello There!
Inadequate intakes of folate during pregnancy are associated with neural tube defects in the fetus.

Answer:
Durante el ciclo de división celular, la célula madre duplica sus cromosomas, lo que genera dos conjuntos idénticos.
Cuando la célula se divide para convertirse en dos células, cada célula hereda un conjunto de copias de cromosomas.
En muchas divisiones, las células hijas son idénticas a la madre, una célula de piel se convierte en dos.
Espero que ayude :)
Explanation:
It diffuses in the alveoli.
Inside the alveoli, oxygen moves across thin walls to tiny blood cells called capillaries<span> and into your blood. It is then picked up by a chemical called </span>haemoglobin<span> in the red blood cells that carry it around your body.</span>
Hope this helps.
