within human populations, it is unethical to force people to mate with each other in order to map disease genes. how do scientists go about determining where the disease genes are located?

Answers

Answer 1

Knowing which genes—when they are dysfunctional—cause which diseases will make it easier to diagnose patients and give information on the functional traits of the mutation.

With the development of modern high-throughput sequencing methods and the knowledge gained from the expanding area of genomics, illness genes are being identified more quickly, enabling researchers to find more complex mutations. Techniques for identifying disease genes frequently use the same general process. First, DNA is taken from a number of patients who are thought to share a hereditary condition. Their DNA samples are then examined and screened to identify likely areas where the mutation may exist. The following list includes these methods. The mutant gene should be located in the region that overlaps when these likely locations are lined up next to one another. Candidate genes are looked for in a region of the genome where sufficient sequence information is available. These genes' coding areas are then sequenced up until a mutation is found or another patient is identified, at which point the research can be repeated, potentially focusing on a smaller region of interest.

what is the cause of the massive amount of programmed cell death of nerve cells (neurons) that occurs in the developing vertebrate nervous system, and what purpose does it serve?

Answers

It is a way for the body to get rid of unwanted or abnormal cells. Cancer cells interfere with the process of programmed cell death. Also known as apoptosis.

Apoptosis is mediated by proteolytic enzymes known as caspases that cause cell death by cleaving certain proteins in the cytoplasm and nucleus. All cells contain inactive precursors of caspases known as procaspases. These procaspases are usually triggered by cleavage by other caspases, resulting in a proteolytic caspase cascade.

when the membrane moves, the____on the spiral organ hair cells distort because they are anchored by the tectorial membrane.

Answers

When the membrane moves, the stereocilia on the spiral organ hair cells distort because they are anchored by the tectorial membrane.

The spiral organ, also known as the cochlea or cochlear duct, is a structure found in the inner ear that is responsible for detecting sound. It contains hair cells, which are specialized sensory cells that convert sound waves into electrical signals that can be interpreted by the brain. The hair cells are covered by a thin membrane called the tectorial membrane, which is attached to the stereocilia, the hair-like projections on the surface of the hair cells.

When sound waves enter the ear and cause the membrane to move, this movement is transmitted to the tectorial membrane, which in turn causes the stereocilia to bend and distort. This distortion of the stereocilia triggers the hair cells to produce an electrical signal that is sent to the brain for interpretation.

A certain gene codes for a polypeptide that is 120 amino acids long. Approximately how many nucleotides long is the mrna that codes for this polypeptide likely to be?.

Answers

When a gene encodes a polypeptide containing 120 amino acids, 360 nucleotides are required in the mRNA to encode that polypeptide.

Each codon of the mRNA molecule consists of 3 nitrogenous bases because it is called a triplet, and each nucleotide consists of 1 nitrogenous base, 1 pentose sugar, and 1 phosphate so if there are 3 nitrogenous bases it can be said that there are also 3 pentose sugars and 3 phosphates which produce 3 nucleotides at each codon. So that it can be concluded that each codon consists of 3 nucleotides.

Thus, each amino acid is defined by three consecutive nucleotides (i.e., codons) so that if there are 120 amino acids, it is defined by 360 nucleotides (120 x 3 = 360 nucleotides).

The correct response is a. capsular polysaccharides. The capsular polysaccharides of the different Streptococcus pneumoniae serotypes vary.

Bacterial capsular polysaccharides (CPSs) are important virulence factors that offer protection to those who carry them from a variety of environmental stresses, most notably from the immune system when infecting their animal hosts. The primary virulence factor of bacteria is the capsular polysaccharide (CPS), which makes up the exterior layer of the bacterial cell (Martens et al., 2004). This pathogen has numerous distinct immunological kinds that can be distinguished by its CPS. Streptococcus pneumoniae's polysaccharide capsule, which dominates the organism's surface, is crucial to virulence because it interferes with the host's opsonophagocytic clearance systems. Many bacteria have polysaccharide capsules, which are prokaryotic structures often made of repeated oligosaccharides. These capsules, which are normally made up of just one polysaccharide, are found outside both the peptidoglycan layer and the outer membrane of gram-positive and gram-negative cells, respectively.
