Genetics Answers

Write a brief outline of the mechanisms in which DNA is used to generate protein. You do not need to provide a fine level of detail, but ensure you reflect on the key points in the process and mention any major differences between the mechanism in prokaryotic and eukaryotic cells

Discusses trends in biotechnology and the field of metagenomics.

explain why metagenomics is probably the most revolutionary application of genomics. What application of genomics would best serve your community and why?

Why an electron microscope rather than a light microscope was used to produce a cell photograph

Describe how the natural pigment within the hair affects the choice of colour and the colouring products and the possible need to pre-lighten

Horizontal gene transfer is made possible by the existence of mobile genetic elements, such as plasmids (extrachromosomal genetic material), transposons (“jumping genes”) and bacteria-infecting viruses (bacteriophages). These elements are transferred between organisms through different mechanisms, which in prokaryotes include transformation, conjugation, and transduction.
Finally, discuss the danger that antibiotic resistance poses in today’s society, consider how man has contributed to this and suggest any strategies that you think may be able to halt it or prevent its expansion

As with all proteins, beta-lactamase is encoded by a section of DNA – but how does that DNA and the ability to produce a new protein transfer from one population of bacteria that have resistance to another population that don’t?

Other than direct transfer from parent to daughter cell, horizontal transmission of DNA between different genomes also occurs. Horizontal gene transfer is made possible by the existence of mobile genetic elements, such as plasmids (extrachromosomal genetic material), transposons (“jumping genes”) and bacteria-infecting viruses (bacteriophages). These elements are transferred between organisms through different mechanisms, which in prokaryotes include transformation, conjugation, and transduction.



Write a sentence for each of these mechanisms describing the manner in which the DNA can be transferred from one cell to another.

What are some things that can damage a farmer’s crops?





What can farmers do to protect their crops?

A useful devise in predicting possible offspring

A sneeh can be tall, medium , or short . If you cross two medium Sneech's, what are the phenotype and genotype percents of the offspring?

In reference to the Hardy-Weinberg equilibrium lab; Koi fish with the phenotype “White” is a result of a homozygous recessive allele.

If you have a Koi pond with 4 white fish (with a frequency of .25) and 12 orange fish (caused by the dominant allele and a frequency of .75), what would the frequency of the spotted fish phenotype for the population?

2pq = 0.5
q2 = 0.5
2pq= 0.25
2pq = 2.0

which is the correct option ?
