The keratinocytes within stratum lucidum are flattened and filled with the protein ______, an intermediate product in the process of keratin maturation.
Answers
The keratinocytes within the stratum lucidum are flattened and filled with the protein eleidin, an intermediate product in the process of keratin maturation.
The stratum lucidum is a layer of the skin found in the palms of hands, fingertips, and soles of the feet, among other regions. It is thin and transparent, and its cells, known as keratinocytes, are filled with a protein called eleidin. Eleidin is an intermediate product in the process of keratin maturation, which is a crucial part of skin protection and maintenance.
Keratin is a fibrous protein that forms a waterproof, protective covering on the skin, hair, and nails. Keratinization is a process in which keratinocytes are transformed into tough, keratin-filled cells that help to protect the body from environmental stressors such as heat, cold, and abrasion. The process of keratinization starts in the stratum basale, the deepest layer of the epidermis, and continues through the other layers of the skin, including the stratum lucidum until the cells are finally sloughed off at the surface of the skin.

What is an allele, simply defined?We refer to the alternative form(s) or versions of a gene as "alleles." The alleles for each autosomal gene that a person inherits from each parent are typically grouped into categories. Alleles are commonly referred to as normal, wild-type, abnormal, or mutant alleles.
Alleles are any of two or more genes that may alternately occur at a specific location (locus) on a chromosome. They are also known as allelomorphs. The expression (phenotype) of a particular trait can be influenced by a single allele, a pair of alleles, or multiple alleles.

Which energy level has the least energy?

Answers
Answer:
n = 7
Explanation:
The Energy of a system decrease through the levels. Is simple to understand that:
1. All energy cames from sun.
2. Organisms that can absorve that energy acumulates X quantity. The more comum way to do that is the photosynthesis, which turns solar energy into glucose, basically. (Equation of photosynthesis: 6H2O + 6CO2 = C6H12O6 + 6O2)
3. The first heterotrofic organism eats a plant, for example. Then he gets a part of that energy, aproximately 0,3X - the efficiently variates for each organism, but it's low. For example, we need to took 30 Kcal to use 100 Kcal from a common protein. And we need to lose more energy for every process that we will do in our body. Remember, or now know, the second law of termodinamics: is impossible to fully convert the ceded energy into WORK in a open system.
4. The next organism eats the first, getting a part of his energy. 0,3 x 0,3X
So, as this process repeats for all organisms, we can easily conclude that the last organism has the least energy.

Analysis of synteny is based on ______
A. the comparison of protein domains across paralogs
B. comparison of protein domains across orthologs
C. the relative position in the genome of orthologs
D. the relative contribution of gene splicing in creating isoform diversity
Answers
MRNA isolation strategies rely on the hybridization of poly A tails to oligo dT beads.
Analysis of synteny is based on the relative position in the genome of orthologs.
Poly A tails are present at the 3' end of mRNA molecules, and they can be specifically targeted using oligo dT beads, which have complementary sequences to the poly A tails. By binding to the poly A tails, mRNA molecules can be selectively isolated from the total RNA mixture, which may also contain other types of RNA such as ribosomal RNA and transfer RNA. This allows for the enrichment and isolation of mRNA for further analysis and study.
Synteny refers to the conservation of the relative order of genes or genetic loci between different organisms or within the genome of a single organism. By comparing the positions of orthologous genes, which are genes in different species that share a common ancestor, scientists can determine the degree of synteny and identify genomic regions that have been conserved over evolutionary time. This information can provide insights into gene function, evolutionary relationships, and the organization of genetic material within genomes.

In the metaphase, mitotic spindle attaches to the chromosome's centromeres and lines them up in the middle of the cell. The correct option is D.
What are spindle fiber?Spindle fibers form a protein structure that divides a cell's genetic material. The spindle is required to split the chromosomes in a parental cell evenly into two daughter cells.
During metaphase, these spindle fiber gets attached to centromere of the chromosome and align the chromosome at the equator.
Long protein fibers known as microtubules prolong from the centrioles in all directions, forming a spindle. Some microtubules connect the poles to the chromosomes via protein complexes known as kinetochores.
Spindle fibers from the opposite side of the cell connect to the chromosome's both these sister chromatids.
They connect at the kinetochore, which comprises a disc or protein on each side of the centromere. The chromosomes will be moved by the spindle fibers until they are aligned at the spindle equator.
