If a mutation occurs when forming a germ cell the mutation could be passed on to the next generation. If a gene is altered in a germ cell, the mutation is termed a germinal mutation. Because germ cells give rise to gametes, some gametes will carry the mutation and it will be passed on to the next generation when the individual successfully mates.
A mutation passed to the next generation when acquired mutation occurs in an egg or sperm cell. Once an acquired mutation is passed down, it is a hereditary mutation. Acquired mutations are not passed down if they occur in the somatic cells, meaning body cells other than sperm cells and egg cells.

Meninges, the protective coverings of the central nervous system, come in two varieties: cranial and spinal. The dura mater, arachnoid mater, and pia mater are the three connective tissue layers that make up most of their structure.The fundamental distinction between cranial and spinal meninges is that, while spinal meninges are protective coverings for the spinal cord, cranial meninges are those for the brain, consisting of channels in the dura mater between various areas of the brain called Dural folds. Additionally, the dura mater in the spinal meninges only has one layer, whereas the dura mater in the cranial meninges has two levels.

The Kaposi's sarcoma-associated herpes virus was identified in a unique and unusual category of AIDS-related lymphomas that generally manifest as lymphomatous effusions with no apparent tumor tissues.
Description of the Statement-
KSHV is consistently present in these body cavity-based lymphomas, and several other characteristics make them stand out. To test this theory, 19 malignant lymphomatous effusions that did not contain a contiguous tumor mass were examined for their symptomatic, cytologic, immunophenotypic, infectious, and molecular features. KSHV was found in 15 of the 19 lymphomas. The c-myc gene rearrangements and Burkitt-like morphology among all 4 KSHV-negative lymphomatous effusions suggested that these were Burkitt-type lymphomas developing in the bodily cavities.Furthermore, these lymphomas developed in men, usually but not always in connection with HIV infection, and homosexual behavior was a risk factor.Learn more about lymphomas here:

In cell signaling, after a signal is sent, _______\.\* 2 points a. some activity in a target cell changes b. signal molecules bind to receptors on target cells c. mitosis begins d. signal transduction is turned off
In cell signalling, after a signal is sent, signal molecules bind to receptors on target cells and some activity in a target cell changes.
There are three stages in cell signalling :
1. The process of reception occurs when a signalling molecule from the extracellular environment is recognized by a cell. The chemical signal, which is also known as a ligand, is recognized as a signal when it attaches to a receptor protein either on the exterior of the cell or on the interior of the cell.
2. Transduction: This process occurs when the signalling molecule interacts with the receptor, which causes a change in the protein that makes up the receptor. The process of transduction is kicked off by this modification. In most cases, signal transduction occurs through a pathway that consists of numerous stages. The signal transduction route contains relay molecules, each of which influences the subsequent molecule in the pathway.
3. Reaction: In the third and last step, the signal causes a certain cellular response.

If [e]t was the concentration of lactase in the kinetics trials, what expression gives the concentration of lactase in the commercial preparation of this enzyme?
DF = 1/250 x 1/2
Vt = Et
Vf = final concentration of lactase in the commercial preparation
DF = Vt / Vf
Vf = Vt / DF
Vf = Et / (1/250)(1/2)
Vf = Et x 500
The commercial preparation was first diluted by 1 - 250 to prepare the stock solution, and it was further diluted by 1 -2 by mixing with the substrate stock solution to perform the kinetics experiments.
Therefore, the dilution factor is done when you take whatever you initial volume was - in this case 1mL - and divide it by the new diluted volume - 0.1mL + 25mL. Then we get is 0.1/25.1, which is more easily solved as 1/250.
Since, this was a double dilution, 1mL of the initial dilution was diluted further with 1mL of substrate. So the second dilution factor will be 1/(1+1) = 1/2.

IL-22 inhibits epidermal di erentiation and induces proinflammatory gene expression and migration of human keratinocytes
The given statement that IL-22 inhibits epidermal decentration and induces proinflammatory gene expression and migration of human keratinocytes holds true
What is IL-22?IL-22 belongs to a family of cytokines structurally related to IL-10, including IL-19, IL-20, IL-24, and IL-26. In contrast to IL-10, IL-22 has proinflammatory activities. IL-22 signals through a class II cytokine receptor composed of an IL-22-binding chain, IL-22RA1, and the IL-10RB subunit, which is shared with the IL-10R. In the present study, we show that short-term cultured human epidermal keratinocytes express a functional IL-22R but no IL-10R. Accordingly, IL-22 but not IL-10 induces STAT3 activation in keratinocytes. Using a cDNA array screening approach, real-time RT-PCR, and Western blot analysis, we demonstrate that IL-22 up-regulates, in a dose-dependent manner, the expression of S100A7, S100A8, S100A9, a group of proinflammatory molecules belonging to the S100 family of calcium-binding proteins, as well as the matrix metalloproteinase 3, the platelet-derived growth factor A, and the CXCL5 chemokine. In addition, IL-22 induces keratinocyte migration in an in vitro injury model and down-regulates the expression of at least seven genes associated with keratinocyte differentiation. Finally, we show that IL-22 strongly induces hyperplasia of reconstituted human epidermis. Taken together, these results suggest that IL-22 plays an important role in skin inflammatory processes and wound healing.

In a hardy-weinberg population with two alleles, a and a, that are in equilibrium, the frequency of the allele a is 0. 3. What is the frequency of individuals that are homozygous for this allele?.
Here, given-
homozygous alleles 'a' have a frequency of 0.3.
Also the alleles are in equilibrium in a Hardy-Weinberg population. The frequency of individuals that are homozygous for this allele are= 0.49.
The Hardy-Weinberg equilibrium can be defined as the principle which states that the variation in the genetic makeup of a population remains constant and unchanged till there are no external interferences, influencing the population.
Calculation-
[tex]p + q= 1\\0.3 + q= 1\\q= 1- 0.3\\q= 0.7\\[/tex]
Then to find the frequency of the individuals homozygous for this allele the following formula needs to be used-
[tex]p^{2} + 2pq + q^{2} = 1\\Here,\\p^{2}= dominant homozygous frequency\\2pq= heterozygous frequency\\q^{2}= recessive homozygous frequency\\[/tex]

Why do nonsense mutations tend to impact the final protein product more than missense mutations?
Nonsense mutations tend to impact the final protein product more than missense mutations because they produce shorter proteins due to the precense of the premature stop codon.
What are the types of point mutations?Although, in some cases, mutations make the resulting proteins more efficient, usually, they make them less efficient than they should be.
In those cases in which the mutations turn to be beneficial for the protein function, it is favored by natural selection, and it fixates. This is what leads to evolution.
If the mutation is not favorable, it just gets lost.
When a change occurs in a single base pair, it is known as a point mutation.
Points mutations might be either silent, missense, or nonsense.
In silent mutations, the resulting mRNA codon codes for the same amino acid as the unmutated sequence. However, if the mutation causes the mRNA codon to code for a different amino acid, this mutation is a missense mutation. Finally, if the mutation causes mRNA codon to be a premature stop codon, we are referring to a nonsense mutation.Missense mutations might alter the protein's function or not, depending on the mutation site and on wheather if the mutated amino acid is near or not to the active site. However, the protein length is the same.
Nonsense mutations change the original codon for a premature stop codon that should not be there. Hence, the protein will be shorter and there are higher chances of altering its functions.
Nonsense mutations tend to impact the final protein product more than missense mutations because they produce shorter proteins due to the precense of the premature stop codon.
