Proteins (Polypeptides with a unique amino acid sequence) are required to guarantee that the accuracy of replication is compatible with the low frequency of errors that is needed for cell reproduction Helicases unwind the two strands of parental DNA and creates the replication fork; single strands binding proteins keep the single strands from reuniting
Cell membranes are first proposed to be composed of phospholipid bilayers by Singer and G. Nicolson.
<h3>What do you mean by cell membrane ?</h3>
A cell membrane, often referred to as a plasma membrane, is present in every cell and serves as a barrier between the interior of the cell and the outside world. The cell membrane is a lipid bilayer that is semipermeable. The passage of chemicals into and out of the cell is regulated by the cell membrane.
- As a result, the cell membrane has two functions: first, it acts as a barrier to keep the cell's components in and undesirable substances out, and second, it acts as a gate to allow the entry of essential nutrients and the exit of waste products.

Tap water would be the control group of the experiment.
no. a person cannot be carrier of a dominant genetic disorder. if a certain disorder is a result of dominant gene both the homozygous and heterozygous individuals are sick and no one of them is carrier. The carrier state is seen only in a situation where genetic disorder is expressed when individuals inherits recessive alleles each from each parent. for someone to be a carrier in this situation, he/she must be heterozygous for certain disorder that is only expressed when an individuals is homozygous of recessive allelles.
