solong [7]
Replication starts at the ORIGIN OF REPLICATION.
In prokaryotes which has close double stranded DNA molecule, replication usually starts from a single origin of replication and it proceeds around the circle bidirectionally, that is, in both directions. The process of replication in prokaryotes is very rapid and it produces only a few errors.<span />

Ok the role of the cell membrane in regulating how nutrients are gained and waste products lost.​
pshichka [43]

Answer:

The cell membranes controls what goes in and out by having protein channels that perform their role accordingly sometimes like funnels and like a pump in different cases.

When a channel open in the plasma membrane it allows molecule to pass through, in this case there is no requirement for energy so it is a passive transport.

Gases and food particles broke down in water must be assimilated and waste or harmful substance and molecules must be remove. For most cells, this type of selective transport of all materials all through the cell must happen through the plasma membrane.

PKU (Phenylketonuria) is an autosomal recessive disease, in which the synthesis of amino acid Tyrosine from Phenylalanine is blo
prisoha [69]

To calculate the frequency of the heterozygote genotype (Pq) for this gene we must use the Hardy-Weinberg equation ( p2 + 2pq + q2 = 1 ). This equation relies on the Hardy-Weinberg principle, a model in population genetics that states that the frequency of the alleles in a population is never changing, only the combinations (the genotypes) are changing.

If there are only two alleles (variations) of this gene in a population, then their frequencies should add up to 1 (100%). From this, we can calculate the frequency of the q allele.

p +q=1

0,3 +q=1

q= 1-0,3

q= 0,7

Now hat we have the frequency of the q allele we can use the HW equation to calculate the frequency of the heterozygotes.

p^{2} + 2pq + q^{2} = 1

(0,3)^{2} + 2pq +(0.7)^{2} = 1

0,09 + 2pq +0.49= 1

2pq +0,58= 1

2pq= 1-0.58

2pq=0,42

The freqency of the heterozygotes in this population is 0.42

If an enzyme inhibitor binds at a site other than the active site of the enzyme, the nature of the inhibitor is described as
icang [17]

Answer:

B. non-competitive

Explanation:

As opposed as competitive inhibition, the non-competitive one does not bind with the active region of the enzyme. However, it does reduce the efficiency of the reaction because it changes the protein structure, making it unavailable for substrate.

Reversibility is related to the possibility of the reaction to be undone. If the bond is covalent, the enzyme will not return to its active state, so that would be a non-reversible bind.
