Answer:
A and C
Explanation:
X-linked recessive diseases are disorders caused by a mutation on the X chromosome causes the phenotypic expression in males and only when it is homozygous for females.
A small percentage of women can display the disease phenotype on rare phenomenon such as;
- X-inactivation that favors inactivation of the normal X chromosome
- Turner syndrome (a sex-chromosome aneuploidy in which women have only one X chromosome)
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.
The correct answer is:
A - They produce identical daughter cells.
Knowing the fact that around sixty percent of the human body is water, which consists of two hydrogen atoms and one oxygen atoms, and that other biomolecules like proteins also have oxygen atoms in their structure it's not a surprise that the percentage of oxygen in the human body mass is that high.
Even though there are two hydrogen atoms and only one oxygen atom in the water molecule, the oxygen atom has 16 times more mass than the hydrogen atom and therefore has a bigger contribution to the overall body mass.
