Question

Answer in other please, 1 is priority, then 2 and then 3.

1.

Based on what you have studied so far you are aware that small changes in the genotype can alter the phenotype of organisms as can larger changes and mutations. Reflect on a minimum of 2 different possible variations that can lead to genetic disorders include the name and the changes involved.

2.

Based on what you have studied about Mitosis and Meiosis in Topic 4, what would you observe on an arresting human cell in the metaphase stage of mitosis and meiosis I after painting chromosomes with a molecular probe? Also explain the possible problems you can foresee if Polymerase enzymes were defective or non-functional.

3.

Who is Marshall Nirenberg? What is the significance of his “Cracking the code Study?” Refer to the Codon Table for mRNA in the text and comment with your cool observation skills.

Explanation / Answer

1. In United States, One elsewhere of every 700 young are birth with an extra chromosome . Down syndrome is the majority in frequent genetic disorder and about 6,000 infants are born with this genetic disorder each year in the United States. It generates when the irregular cell division upshot in extra genetic substance from chromosome 21. The indication of this genetic disarray repeatedly leads to mental disorder that are homogeneous to those of 8 year olds and source of modifications.

2. Some of the feasible issues that you can predict if Polymerase enzymes were imperfect or non-functional can source for mutations in the DNA and this will upshot in your body behaving.

The part of the DNA polymerase is to reproduce the DNA when the cell cleave and additional DNA polymerase enzymes assist to renovate and preserve the DNA. If the polymerase enzymes were to flatter imperfect or non-functional, the DNA drive will not be in the actual sequence, possibly even harm to the DNA, and this can show to some of the majority of usual disarray. If the DNA flatter harmful or inappropriate, this would upshot in the demise of cells if the DNA was unfit to furnish the blue print for protein building for cells.

3. Marshall Nirenberg was a “biologist who decode the genetic key of life, obtainted a Nobel Prize for his procurement”, but in future death at the period of 82 age interior in his home. The importance of his “Cracking the code research” was that he explained the genetic key by inauguratating“ regulation by which the genetic instruction in DNA is interpret into proteins, the active parts of livelihood cells.” Nirenberg was familiar for his effort on cracking the genetic key.
