A recent study of a model organism found that a specific HMG protein localized mainly to the ends of chromosomes. Given this result, the site of localization for this HMG protein would correspond to regions in humans that Contain heterochromatin similar to that of centromeres.
Telomeres are regions at chromosomal ends that are time and again truncated with every round of the cellular department. Centromeresjoin sister chromatids and are required for correct chromosome division for the duration of mitosis.
Notwithstanding their different chromosomal locations, each telomere and centromere are composed of heterochromatin, a tightly condensed complex of DNA wrapped around histones.
Due to its structurally restrictive form, heterochromatin is transcriptionally inactive, which means that proteins liable for regulating gene expression can't get entry into the tightly packed DNA. As an end result, hetechromatic regions are often gene-bad and incorporate repetitive DNA.

Which parts of photosynthesis occur in the thylakoid membranes of the grana?.
Answer:
The light-dependent reactions take place in the thylakoid membranes in the granum (stack of thylakoids), within the chloroplast. Figure: The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions).
Explanation:
Each stack is called a granum (the plural is grana) which is suspended in a fluid called stroma. The light-dependent reactions occur in the grana; the light-independent reactions take place in the stroma of the chloroplasts.

In a Hardy-Weinberg population with two alleles, A and a, that are in equilibrium, the frequency of allele a is 0.2. What is the frequency of individuals that are heterozygous for this allele
In a Hardy-Weinberg population with two alleles, A and a, that are in equilibrium, the frequency of allele a is 0.2. The frequency of individuals that are heterozygous for this allele is 0.32.
Hardy Weinberg Equilibrium Principle A stable, idealized population's constant frequency of alleles and genotypes is described by the Hardy-Weinberg equilibrium principle. In a sizable population, random mating, or spontaneous mutations are necessary for Hardy-Weinberg equilibrium.The Hardy-Weinberg equation dictates that the sum of the allele frequencies for each allele at the locus must equal 1, therefore p + q = 1. The Hardy-Weinberg equation is also written as p2 + 2pq + q2 = 1, where p is the population's frequency of the "A" allele and q is that of the "a" allele.
The homozygous genotype AA frequency is represented by p2, the homozygous genotype aa frequency by q2, and the heterozygous genotype aa frequency by 2pq in the equation.
Here, q = 0.2. Because of this, p = '1- q = 1 - 0.2 = 0.8.
The population of individuals who are heterozygous will now be 2pq, or 2 * 0.8 * 0.2 = 0.32.
Hence, This indicates that the population is heterozygous with a frequency of 0.32.

The picture below shows a soil texture triangle.
Image of a soil texture triangle. Each side is labeled one of the three main soil types—silt, clay, and sand—and is divided into percentages, from 0 to 100. Each point in the triangle corresponds to a different soil texture, consisting of a different combination of silty, sandy, and clay soils. For instance, the top part of the triangle contains soils that range from approximately 50 percent clay to 100 percent clay. All these different soils are considered clays. Soils located farther down the triangle contain an increasingly small percentage of clay; for example, silty clay soils are primarily silt, with more clay than sand, and sandy clay soils are primarily sand, with more clay than silt. Soils located in the middle of the triangle contain roughly equal percentages of clay, sand, and silt; these soils are called “loam.” There are silty loam soils, which contain more silt than clay or sand; clay loam soils, which contain more clay than silt or sand, and sandy loam soils, which contain more sand than silt or clay. There are also silty clay loam soils and sandy clay loam soils.

HOCOOH matches the structural formula to the chemical formula
The structure contains an OH group attached with the carboxylic group, so the correct option is HOCOOH.
The carboxylic group contains an alkyl chain attached to the -COOH group. By far, the most acidic organic groups are the carboxylic acids.
The carbon atom in the carboxylic acid contains a double bond with the oxygen and a single bond with the hydroxyl group.

Functional regeneration of axons occurs more frequently in the peripheral nervous system (PNS) than in the CNS because of two main reasons which are-
The environment in the central nervous system is not suitable for the regeneration or repair of axons.The axons of the neurons in the CNS cannot upregulate genes for the growth or regeneration of the axons. Whereas the axons in the PNS can upregulate these genes to a much greater extent than the CNS.The central nervous system(CNS) and the peripheral nervous system(PNS), are the two branches of the nervous system in the body. The central nervous system consists of the spinal cord and the brain. While the peripheral nervous system consists of the nerves and neurons that arise from the spinal cord and the brain.
