APC Question: Researchers determined the average amount of time that a particular type of eukaryotic cell spends in each phase of the cell cycle. The data collected by the researchers are represented in Figure 1. The average amount of time spent by a particular type of eukaryotic cell in each phase of the cell cycle. Based on Figure 1, what percent of the time required to complete a full cycle do the cells typically spend in interphase?
A.) 5%
B.) 35%
C.) 50%
D.) 95%
Cell spends about 95% of its time in interphase.
The G1, S, and G2 phases are all considered to be interphase, which is the part of the cell cycle that is not accompanied by changes that can be seen under a microscope. The cell expands (G1), copies its DNA (S), and gets ready for mitosis during interphase (G2). A cell going through interphase is not just dormant. Since a cell in interphase is actively synthesising proteins, transcribing DNA into RNA, absorbing external material, processing signals, to name just a few tasks, the term quiescent (i.e. dormant) would be deceptive. Only in terms of cell division is the cell dormant (i.e. the cell is out of the cell cycle, G0).

What is a punnet square?A punnet square in genetics is a graphical representation used to determine the probability of an offspring expressing a particular genotype.
A punnet square makes use of the alleles of gametes to deduce the genotype of the offsprings that will be produced from a cross.
According to this question, a homozygous green pea plant is mixed with a homozygous yellow pea plant. The punnet square is shown in the attached image.
The allele for the green pea is G while the allele for the yellow pea is g. G is said to be dominant over g (recessive), which means that in a heterozygous condition i.e. Gg, the green trait will be observed phenotypically.
If GG and gg genotypes are crossed, all of the offsprings will possess a Gg genotype, hence, 100% of the offsprings will be green.

The prevalence of this allele in the community is around 2% of the U.S. population.
Using Hardy-Weinberg equilibrium,
q2 = 1 ÷ 10,000 = 0.0001
q = √0.0001 = 0.01
p = 1 − q = 1 − 0.01 = 0.99
The carriers are heterozygous. Therefore, 2pq = 2 (0.99 × 0.01) = 0.0198 = 1.98%
According to the Hardy-Weinberg equilibrium, genetic diversity in a population will remain constant throughout time in the absence of disruptive factors.

which measure of biodiversity takes into account the number of species present and the relative abundance of the species present?
The species evenness measure of biodiversity takes into account the number of species present and the relative abundance of the species present.
The measure of biodiversity that takes into account the number of species present and the relative abundance of the species present is called Species Richness.
Step 1: Species richness is a measure of biodiversity that takes into account the number of species present in a given area.
Step 2: Species richness is calculated by counting the number of species present in a given area. This number is then compared to other areas, to assess the relative biodiversity of each area.
Step 3: Species richness also takes into account the relative abundance of the species present. This means that the relative abundance of a species is taken into consideration when calculating species richness.
Step 4: The relative abundance of a species is determined by counting the number of individuals of a particular species present in a given area. This number is then compared to other areas, to assess the relative abundance of the species in each area.
Step 5: The total species richness of an area is then determined by combining the number of species present with the relative abundance of the species present. This allows for a more accurate assessment of biodiversity in a given area.

what would be the consequence of a mutation in a bacterial cell that produces a defective aminacyl-trna sythetase that attaches a lysine instead of the normal phenylalanine to trnas
Lysine will be used as an amino acid in place of phenylalanine in the cell's proteins.
At amino acid sites determined by the codon AAA, lysine rather than phenylalanine will be present in proteins inside the cell. By adding phenylalanine to tRNAs with lysine-specific anticodons, the cell will fix the flaw. The body is unable to produce essential amino acids. They must therefore originate from food. Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the nine essential amino acids. Being an essential amino acid, phenylalanine cannot be produced by the body and must be consumed through diet. Tyrosine is a non-essential amino acid that can be created in the liver by hydroxylating phenylalanine when consumed.

suppose 20 glucose molecules are formed during gluconeogenesis. The amount of pyruvate, atp, and nadh molecules required are :
number of pyruvate: 40 Number of ATP: 120 Number of NADH: 40
1 molecule of glucose is created from 2 pyruvate molecules. It takes 20 molecules of pyruvate to make 20 molecules of glucose, or 2*20 molecules.
One molecule of glucose is produced using 6 molecules of ATP. Therefore, there will be 6*20=120 ATP for 20 molecules of glucose.
In the process of gluconeogenesis, 2 NADH molecules are used to make 1 molecule of glucose. In other words, it will be 2*20=40NADH for 20 Glucose molecules.
A process known as "gluconeogenesis" converts non-carbohydrate substrates like lactate, amino acids, and glycerol into glucose (parent 1).
