Eukaryotic organisms solve the problem of time constraints on replication of DNA by?
Eukaryotic organisms solve the problem of time constraints on replication of DNA by using multiple origins of replication along each chromosome. This allows for DNA replication to occur simultaneously at several points, speeding up the process. Additionally, eukaryotic cells have specialized enzymes and proteins that help ensure efficient and accurate replication of DNA.
Mutation that occurs at the chromosome level resulting in changes in the gene distribution?
Chromosomal mutationAneuploidyAneuploidy occurs when a cell has the wrong number of chromosomes either due to an extra or missing chromosome. This type of problem can occur during the anaphase part of M phase. Through a process called nondisjunction the chromosome pairs may not separate properly causing one of the daughter cells to receive both copies of a chromosome and the other daughter cell receives no copies of that chromosome. Therefore, one daughter cell will have an extra chromosome and the other daughter cell will have a missing chromosome. Also, this problem can occur if there is a lag during anaphase. When the pairs of chromosomes separate to each side of the cell, a chromosome may travel too slow which would cause it to not be incorporated into the new cell. This new cell would be missing a chromosome. DeletionChromosome Deletions occur when the cell is missing a portion of a chromosome. This type of problem can occur during S phase if there is a problem during DNA replication or other parts of interphase if the DNA is damaged. DuplicationChromosome Duplications occur when a cell has a repeated portion of a chromosome which causes the cell to have extra information. This type of problem can occur during S phase if there is a problem during DNA replication. InversionChromosome Inversions occur when a piece of a chromosome breaks and that piece is reattached in the opposite orientation. This type of problem can occur during interphase if the DNA is exposed to damage that causes DNA breakage. InsertionChromosome Insertions occur when a piece of a chromosome that had broken reattaches in a location where this genetic material is not typically found. This type of problem can occur during interphase if the DNA is broken and then repaired by attaching to a different location. TranslocationThere are two types of translocations: reciprocal and robertsonian. A reciprocal translocation occurs when two nonhomologous chromosomes break and then switch genetic material. A robertsonian translocation occurs when two chromosomes break on the p arm near the centromere and then the two q arms attach together while the p arms are lost. Either of these types of translocation can occur at any point during the cell cycle.
Why might missing sections of the X or Y chromosome be a bigger problem in males than deletions would be in one of the X chromosomes in females?
Females carry two X chromosomes and no Y chromosomes. so if one is missing a section, the other will make up for it. For males, who only have one X and one Y chromosome, there is no overlap.
Is it possible for someone to have cat ears and a cat tail when they are born?
It has been seen but they are not called cat ears or tails. Normal shaped ears are sometimes folded in such a way that they look pointed. A chromosome problem is seen in Williams Syndrome and these people sometimes have what are called pointy ears. Humans have been born with tails since the fetus (4-6 weeks) has a tail but it is usually absorbed. These tails have no hair and are very short.
What problem was solved by the invention of the microscopes?
The invention of microscopes solved the problem of being able to see and study very small objects or organisms that were not visible to the naked eye. This led to advancements in biology, medicine, and other scientific fields by allowing researchers to observe cellular structures and microorganisms in detail.

Do dyslexic people have extra or less chromosomes than non-dislexic people?
dyslexia is a disorder of the brain not a chromosome problem.

Is it more common for girls or boys to be color blind?
Boys. The gene that causes the varying degrees of color blindness is recessive and must be present on the X Chromosome. Since boys have only one X Chromosome, it is more common for boys to be color blind than girls. It is still possible for a girl to be color blind, but it is significantly rarer. The problem affects 8% of Caucasian males and 0.5% of Caucasian females.
Why do you do risk assessment?
It is done to determine what issues present a problem that can then have solutions determined to prevent the problem.
