true/false. as dna replication continues and the replication bubble expands, the parental double helix is unwound and separated into its two component strands. this unwinding and separating of the dna requires three different types of proteins: helicase, topoisomerase, and single-strand binding proteins.
True , Helicase - breaks H-bonds between bases; binds at the replication fork
topoisomerase - breaks covalent bonds in DNA backbone; binds ahead of the replication fork
single-strand binding - prevents H-bonds between bases; binds after the replication fork

If the light independent reaction can run without light why does oxygen and glucose production stop ?
The light-independent reactions (Calvin cycle) "fix" CO₂ by producing a substance that may be turned into glucose using chemical energy that was previously accumulated from the light-dependent reactions.
What is meant by glucose?
A basic sugar, glucose has the chemical formula C6H12O6. The most prevalent monosaccharide, a type of carbohydrate, is glucose. The majority of plants and algae produce glucose during photosynthesis from water and carbon dioxide with the help of solar energy, where it is utilised to create cellulose, the most prevalent carbohydrate in nature, in the cell walls.Glucose is the most significant source of energy in all species' energy metabolism.For use in metabolism, glucose is stored as a polymer, mostly as starch and amylopectin in plants and glycogen in mammals.

Calculate the broad-sense heritability (H2 ) of plant height in this species. (Two decimal places (example: 0.12).)
The broad-sense heritability of plant height in this species is -0.20.
The broad-sense heritability (H2) of a trait is a measure of the proportion of the total phenotypic variation that is due to genetic variation. It can be calculated using the following formula:
H2 = (Vg ÷ Vp)
Where Vg is the genetic variance and Vp is the total phenotypic variance.
To calculate the broad-sense heritability of plant height in this species, we will first need to calculate the mean and variance for each strain:
Strain Mean (cm) Variance (cm²)
P1 30.0 3.6
P2 58.0 4.5
F1 44.0 5.7
F2 46.1 10.4
Next, we will use the means and variances of the inbred strains (P1 and P2) and their progeny (F1 and F2) to calculate the genetic and total phenotypic variances.
Vg = (1/2) × (Vp1 + Vp2 - Vf1 - Vf2)
Vp = (Vp1 + Vp2 + Vf1 + Vf2) ÷ 4
Vg = (1/2) × (3.6 + 4.5 - 5.7 - 10.4) = -1.3
Vp = (3.6 + 4.5 + 5.7 + 10.4) ÷ 4 = 6.4
Finally, we can use these values to calculate the broad-sense heritability:
H2 = (Vg ÷ Vp) = -0.2

Which of the following statements about the metabolism of ethanol (which is present in alcoholic beverages) is incorrect? a) Individuals who produce non-functioning aldehyde dehydrogenase exhibit "fastflushing." b) The process requires two enzymes: alcohol dehydrogenase and isopropyl dehydrogenase. c) Individuals who are "fast-flushers" are less likely to become alcoholics.
d) Aspirin interferes with the action of alcohol dehydrogenase. e) All of the above are correct.
The statement that is incorrect about the metabolism of ethanol is b. The process requires two enzymes: alcohol dehydrogenase and aldehyde dehydrogenase.
The metabolism of ethanol in the body involves a series of steps that are primarily carried out by two enzymes: alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH). ADH converts ethanol to acetaldehyde, which is then converted to acetate by ALDH.
"Fast flushing" is a phenomenon that occurs in some individuals who produce a non-functioning form of the ALDH enzyme. This means that the acetaldehyde produced by ADH is not converted to acetate and instead accumulates in the body. This accumulation causes physical symptoms of "flushing," such as redness and warmth of the skin, as well as an increased heart rate and nausea. Individuals who are "fast-flushers" are less likely to become alcoholics due to the unpleasant physical symptoms associated with alcohol consumption. Aspirin interferes with the action of alcohol dehydrogenase which can also cause flushing.
