many studies have suggested a strong genetic predisposition to migraine headaches, but the mode of inheritance is not clear. l. russo and colleagues examined migraine headaches in several families, two of which are shown below. what is the most likely mode of inheritance for migraine headaches in these families? explain your reasoning.

Answers

Answer 1

The characteristic is most likely X-linked dominant in both families because it does not pass down across generations and afflicted people have one affected parent.

It is not X-linked in family 2 because the sick man II-8 has an unaffected daughter. In the case of X-linked loci, an afflicted male would pass on the trait to all of his daughters. In family 1, it might be X-linked or autosomal.

X-linked dominant inheritance refers to genetic conditions associated with mutations in genes on the X chromosome. Her one copy of the mutation is sufficient to cause disease in both males (one X chromosome) and females (two X chromosomes).

Families with X-linked recessive disorders often affect males in each generation, but rarely females. However, in X-linked dominant disorders, mutations in one copy of the X-linked gene cause the disease in both males and females.

Answers

Alternative splicing, intron removal & exon joining, 3' poly-A tail addition, 5' cap addition, All of them occur often in human cell mRNA changes.

The most frequent alternative splicing process in mammalian cells is said to be exon skipping, also referred as cassette exons, which completely skips one or more exons.

Only one exon out of each cluster is incorporated in the final mRNA, with the alternative exons in each cluster being mutually exclusive. As a result of this gene architecture, this gene can produce 480 distinct mRNAs by alternative splicing. Splicing is a rare occurrence in prokaryotes and happens in non-coding RNAs like tRNAs.

How do you split cells in biology?

Answers

To split cells in biology, you can use a process called cytokinesis, which is the division of the cytoplasm and organelles between two daughter cells

In biology, the process of splitting cells is known as cytokinesis. There are two main types of cell division: mitosis and meiosis.

Mitosis is the process of a single cell dividing into two identical daughter cells. It occurs in somatic (body) cells and is used for growth and repair. During mitosis, the DNA is replicated and the cell goes through four phases: prophase, metaphase, anaphase, and telophase.

Meiosis, on the other hand, is the process of a single cell dividing into four non-identical daughter cells. It occurs in germ cells (cells used for reproduction) and is used to create gametes (sperm and egg cells). During meiosis, the DNA is replicated and the cell goes through two rounds of division, resulting in the production of four haploid cells.

what protects neurons and glia from bacterial toxins, infectious agents, etc., and maintains the composition and balance of ions in the interstitial fluid?

Answers

The blood-brain barrier (BBB) protects neurons and glia from bacterial toxins, infectious agents, etc., and maintains the composition and balance of ions in the interstitial fluid.

The blood-brain barrier (BBB) is a specialised structure that protects neurons and glia from bacterial toxins, infectious agents, and other potentially harmful substances while also regulating the composition and balance of ions in the brain's interstitial fluid.

The BBB is a selective barrier formed by the densely packed endothelial cells that line the walls of blood vessels in the brain. Tight junctions connect these cells, preventing molecules and ions from freely diffusing between the bloodstream and brain tissue. Furthermore, endothelial cells are surrounded by astrocyte foot processes, which strengthen the barrier and regulate the exchange of nutrients and waste products between blood and brain tissue.

The BBB is highly selective, allowing only certain molecules to pass through, such as oxygen, glucose, and amino acids, while blocking others, such as large proteins, toxins, and infectious agents. This selective permeability is critical for maintaining the proper chemical environment in the brain, which is required for neurons and glia to function properly.

The BBB is also important in maintaining the ion balance in the brain's interstitial fluid, which is necessary for proper neural function. The BBB, for example, aids in the maintenance of proper levels of potassium and sodium ions in the brain, which are required for nerve impulse transmission.

The pacemaker potential is a type of electrical potential created by cells in the heart and other excitable tissues. It is the electrical signal that initiates an action potential,

A brief electrical signal travels along the cell membrane, triggering cellular activity. The pacemaker potential is generated by a combination of ion channels and voltage-gated ion channels. It is capable of reaching the threshold without stimulation, meaning that it can generate its own electrical signal without any external stimulus. This is due to the concentration gradient of ions across the cell membrane, which creates an electrical potential. The voltage-gated ion channels also help to maintain the pacemaker potential. These channels open and close in response to changes in the membrane potential, allowing ions to flow in and out of the cell and helping to maintain the potential.

the type of chemical linkage that joins the hydrophobic tails to the hydrophilic heads in membrane lipids in bacteria is

Answers

Ester linkage is the sort of chemical bond that connects the hydrophobic tails to the hydrophilic heads in bacterial membrane lipids.

In contrast to archaea, which have membranes made of isoprenoid alkyl chains linked by ether linkages to glycerol-1-phosphate (G1P), bacteria and eukaryotes have membranes made of fatty acids linked to glycerol-3-phosphate (G3P) via ester bonds. This results in the glycerol phosphate backbone having the opposite stereochemistry.

While bacterial phospholipids are made up of straight fatty acids coupled by ester bonds to the enantiomeric glycerol-3-phosphate backbone, archaeal lipids are made up of highly methylated isoprenoid chains that are ether-linked to a glycerol-1-phosphate backbone.

Stop when the square is in its original location and then rotate it in the clockwise direction until the square is in its original location again. You may want to rescale the axis by using axis ([-2,2,-2,2]). Include the M-file. Do not include the figure. Hint: Since you are performing a computation several times, you will want to use two for loops: one loop for the counterclockwise rotation and another one for the clockwise rotation. Think about how many times you will need to go through the loops, keeping in mind that you are rotating the square counterclockwise for a full circle by increments of 7/9 and then rotating the square clockwise back again. clf % clear all settings for the plot S=[0,1,1,0,0;0,0,1,1,0]; D1 = 9/8*eye (2); % dilation matrix p = plot (S(1,:), S (2,:)); % plot the square axis ([-1,4,-1,4]) % set size of the graph axis square, grid on % make the display square hold on % hold the current graph for i = 1:10 S = D1 *S; % dilate the square set(p, 'xdata', S(1,:), 'ydata',S(2,:)); % erase original figure and plot % the transformed figure pause (0.1) % adjust this pause rate to suit your computer. end D2 = 8/9*eye (2); % contraction matrix for i = 1:10 S = D2*S; % contract the square set(p, 'xdata',S(1,:), 'ydata',S(2,:)); % erase original figure and plot % the transformed figure pause (0.1) % adjust this pause rate to suit your computer. end hold off EXAMPLE 2 We can rotate the square S from Example 1 by an angle of a/4 in the counterclockwise direction by multiplying the matrix S by [cos(1/4) sin(1/4) Q = sin(/4) cos(1/4) ] The following code implements the rotation and the resulting picture is displayed in Figure 1. clear all; % clear all variables clf; % clear all settings for the plot S=[0,1,1,0,0,0,0,1,1,0]; plot (S(1,:), S (2,:), 'linewidth', 2); % plot the square hold on; theta =pi/4; % define the angle theta Q=[cos (theta),-sin (theta); sin(theta), cos (theta)]; % rotation matrix QS=Q*S; % rotate the square plot (QS (1,:), QS (2,:),'-r','linewidth', 2); % plot the rotated square title('Example of Rotation'); % add a title legend ('original square', 'rotated square') % add a legend axis equal; axis ([-1,2,-1,2]); % set the window grid on; % add a grid hold off Example of Rotation original square - rotated square -0. 5 0 0.5 1 1.5 2 Figure 1: Original square and rotated square Can you translate the poem the poison tree?
