A cell that has two copies of each chromosome, one from an egg and one from sperm is known as _____.
A cell that has two copies of each chromosome, one from an egg and one from sperm, is known as a diploid cell.
In most sexually reproducing organisms, including humans, the process of fertilization involves the fusion of a haploid sperm cell and a haploid egg cell, resulting in the formation of a diploid zygote. The zygote then undergoes mitosis, a process of cell division that results in the formation of new cells, each with the same number of chromosomes as the original cell.
In diploid cells, the two copies of each chromosome are referred to as homologous chromosomes. One homologous chromosome is inherited from the individual's mother, and the other is inherited from the father. This provides genetic diversity and variability in the offspring.
Diploid cells are found in most somatic cells of the body, with the exception of a few specialized cells, such as gametes (sperm and egg cells), which are haploid. In summary, a cell that has two copies of each chromosome, one from an egg and one from sperm, is known as a diploid cell.

Muscles are not likely to tear from their bones because Select one: a. the tendons are partially ossified at their attachment points to the periosteum. b. a circumferential lamella sandwiches the ends of the tendon onto the surface of an adjacent lamella. c. perforating fibers of collagen attach the tendons and periosteum to the cortical surfaces of bone. d. elastin fibers in the tendon can allow for stretching and recoil of the muscle.
Collagen attach the tendon and periosteum to the cortical surface of the bone. Option C is correct.
Tendons are tough, fibrous connective tissues that attach muscles to bones, and they are designed to withstand the tension and stress generated by muscle contractions. The collagen fibers that make up tendons are arranged in a highly organized manner, providing strength and stability to the tendon.
Perforating fibers of collagen are bundles of collagen fibers that penetrate the periosteum, which is the dense connective tissue that covers the surface of bones. These fibers attach the tendon to the cortical surface of the bone, anchoring the muscle to the bone and providing a strong connection that resists tearing.

what is the advantage of gene expression profiling with cdna chips where rna is reverse transcribed compared to microarray where rna samples are used directly?
Following are the advantage of gene expression profiling with cdna chips where rna is reverse transcribed compared to microarray where rna samples are used directly
One of the advantages of gene expression profiling with cDNA chips where RNA is reverse transcribed, compared to microarray where RNA samples are used directly, is that cDNA chips can provide more accurate and sensitive measurements of gene expression levels.
Reverse transcription of RNA into cDNA allows for amplification of the RNA samples, which can increase the sensitivity of the assay.
This is because the reverse transcription process converts RNA molecules into cDNA molecules, which are more stable and less susceptible to degradation than RNA molecules.
In addition, the amplification step increases the amount of cDNA available for analysis, which can improve the accuracy of the measurements.
In contrast, with microarrays where RNA samples are used directly, there is no amplification step.
As a result, microarrays may be less sensitive and accurate than cDNA chips, especially when analyzing low-abundance transcripts or small amounts of starting RNA.
Additionally, RNA samples are more prone to degradation and variability, which can introduce noise into the data and affect the accuracy of the measurements.
Overall, gene expression profiling with cDNA chips where RNA is reverse transcribed offers the advantage of increased sensitivity and accuracy, which can lead to more reliable and meaningful results. However, it is important to note that both approaches have their own strengths and weaknesses, and the choice of assay should be based on the specific research question and experimental design.

when the hisauxotrophic salmonella strain used in the ames test is exposed to a substance x, no his (wild type) revertants are seen. if, however, rat liver supernatant is added to the cells together with substance x, revertants are seen. do you conclude that substance x is a potential mutagen, and even carcinogen, for human cells? yes or no? explain.
Yes, the rat liver supernatant contains enzymes that convert substance X to a mutagen, and his+ revertant occur.
The Ames test is a popular method for detecting if a certain chemical may cause mutations in the test organism's DNA. It is a biological experiment performed to examine chemical compounds' mutagenesis potential.
The Ames test employs different strains of the bacterium Salmonella typhimurium that have mutations in histidine synthase genes. These strains are auxotrophic mutants, which means they need histidine to thrive but can't make it.
The approach assesses the tested substance's potential to induce mutations that result in a return to a "prototrophic" state, allowing the cells to thrive on a histidine-free media.
Larger creatures, such as mammals, contain metabolic mechanisms that might possibly convert a chemical that is not mutagenic into one that is, or a chemical that is mutagenic into one that is not.
To more successfully assess a chemical compound's mutagenicity in relation to bigger species, rat liver enzymes can be introduced in an attempt to reproduce the Ames Test's effect on the substance being studied.
Optionally, rat liver extract is added to replicate the impact of metabolism, as some chemicals, such as benzo[a]pyrene, are not carcinogenic in and of themselves, but their metabolic products are. On an agar plate, the bacteria are distributed with a little quantity of histidine.
This modest quantity of histidine in the growing medium permits the bacteria to thrive and mutate for an initial period of time.
When histidine is reduced, only bacteria that have evolved to make their own histidine will survive. For 48 hours, the dish is incubated. A substance's mutagenicity is proportional to the number of colonies seen.

The main component of the herbicide ROUND-UP is glyphosate. Amino acids are a common biological substance that glyphosate resembles.
Glyphosate is a synthetic herbicide that was first introduced in the 1970s. It is the active ingredient in many herbicide products, including the popular brand name herbicide Roundup. Glyphosate is used to control the growth of unwanted plants, such as weeds, and is widely used in agriculture, forestry, and gardening. Glyphosate works by inhibiting the activity of the enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) in plants. EPSPS is involved in the shikimate pathway, which is a metabolic pathway that is essential for the biosynthesis of certain amino acids and other aromatic compounds in plants. By inhibiting EPSPS, glyphosate blocks the production of these compounds, which leads to the death of the plant.

The easiest way to characterize budding is as asexual reproduction that produces genetically identical offspring.
A type of asexual reproduction in which offspring develop from the parent organism's reproductive system. Although some species have buds practically everywhere on their bodies, buds frequently only appear in certain places. In yeast, budding typically happens when there is a plentiful supply of nutrients. As the mother grows, this reproductive process results in tiny shoots. The parent yeast nucleus then divides into two, one of which moves into the bud. Yeast often reproduces asexually through a process known as budding.

Transmembrane proteins, also known as integral proteins, are found embedded in the phospholipid bilayer. These essential proteins frequently act as pathways for chemicals to cross cell membranes. In the absence of non-biological solvents, mixes of pure lipids are used to create planar lipid bilayer membranes. The substantial specific capacitance of the solventless bilayers (586-957 nF/cm2), which is equivalent to that of cell membranes but far higher than that of traditional lipid/decane bilayers, distinguishes them from other types of bilayers.
