Genetic engineering.
Does cossing over lead to genetic variation?
Crossing over: exchange of parts of DNA in a homologous chromosome in the area where they come in contact with each other. Then this chromosome splits, during meiosis, to form a daughter cell (gamete) with a haploid number of chromosomes. During fertilization, the two gametes fuse into one cell containing now a diploid number of chromosomes. This process leads to genetic diversity and variation.
Can human genetic engineering be done on adults?
In theory it could. A virus goes into a cell an replaces its DNA to make that cell produce more virus. So in theory we could make a viral infection that would go into the cells and change the DNA, it would be very completed though.
A cell line susceptible to HSV-2 and HIV-1 co-infection.
Where is the genetic material located in a bacterial call-?
The genetic material is located in the nucleoid in a bacterial call.
What are the differences in genetic mapping between haploid and diploid organisms?
As simply as possibly, the difference in genetic mapping between haploid and diplois organisms are the genes. The haploid organism has only one allele which is either dominant or recessive, while the diploid organism has two alleles of which one is dominant and the other recessive.
Heredity is the idea of Darwin's based on fossil and the modern organisms he found basically saying that genetic changes are inherited by later generations.
Biotechnology is a branch of science, it is not a thing which can be found or lost. So this question is not properly framed.
What role does papain play in the extraction of DNA?
Papain contains protease which is an enzyme that is responsible for removing the proteins in DNA. Which would be the histones, in which DNA is wrapped around
What characteristics does an abnormal genetic test have?
An abnormal chromosome analysis report will include the total number of chromosomes and will identify the abnormality found. Tests for gene mutations will report the mutations found.
How does DNA reproduce itself?
DNA reproduces through a set process that begins when it unzips and uncoils. Next, two polynucleotide chains are produced and adenine lines up with thymine. Cytosine lines up with guanine, and then hydrogen bonds form between the pairs. Enzymes join the nucleotides together, and two new DNA molecules are formed.
is the amount of increase in performance that is achieved through artifical genetic improvement programs. This is usually used to refer to the increase after one generation has passed.
DNA chip or also called as DNA microarray is a collection of microscopic DNA spot attached to a firm surface. This is used by scientist to measure the expression level of the large amount of genes or to genotype numerous regions of a genome.
Is chromosome analysis considered genetic testing?
Genetic testing is a type of medical test that identifies changes in genes, chromosomes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a person’s chance of developing or passing on a genetic disorder. More than 77,000 genetic tests are currently in use, and others are being developed.
Genetic testing involves looking for changes in:
Genes : Gene tests study DNA sequences to identify variations (mutations) in genes that can cause or increase the risk of a genetic disorder. Gene tests can be narrow or large in scope, analyzing an individual DNA building block (nucleotide), one or more genes, or all of a person’s DNA (which is known as their genome).
Chromosomes : Chromosomal genetic tests analyze whole chromosomes or long lengths of DNA to see if there are large genetic changes, such as an extra copy of a chromosome, that cause a genetic condition.
Proteins : Biochemical genetic tests study the amount or activity level of proteins or enzymes; abnormalities in either can indicate changes to the DNA that result in a genetic disorder.

Chromosomes consist of two arms that extend out from a specialized region of DNA , called Centromere. Centromere or primary constriction gives a particular shape to chromosomes due to its position. The chromosome extremities or terminal regions on either side are called telomeres.
How do you predict a PCR product size from a gene cloned into an expression vector?
It all depends on where you primers are. Presumably you will have one primer that sits on the cloned gene and one that sits on the vector (that way you only get a product if the gene has cloned successfully). As long as you know where your primers land, it should be easy to work out how big the PCR product will be simply by adding the distance from the primer on the gene to the end of the gene and the distance from the primer on the vector to the end of the vector.
Is working at Goodyear the right thing?
No. Goodyear is a company heading towards bankruptcy and they are headquartered in Akron, Ohio. Distinguished by the having one of the highest number of cloudy days per year, home of a large silver balloon, and close enough to Massilon HIgh School to force your sons to be humiliated by the seniors on their football team. When you get laid off, you will be forced to move because what other company could you work for in Akron, Ohio besides delivering pizza or driving to Cleveland to maintain your slumlord section 8 apartments? Does this sound like a thriving metropolius you want to live in?
What does a Holtzman Ink Blot Test entail?
The examiner hands each card to the subject and asks the test subject what he or she sees in the inkblot. Only one response per inkblot is requested. Occasionally, the examiner may ask the test subject to clarify
What are currently not a benefit to humans brought about by genetic engineering?
functions know by part of the human body are all benifiacal
their are 2 parts of the body has no known functions are the appendix and the part of muscle between nose and upper lip
How do clone troopers in Star Wars get cloned?
On the planet Kamino, the Kaminonians received an interesting request from Master Sypher Dias. He requested a Clone Army for the republic. So the Kamonians sought Jango Fett, a suitable base for the clones. He was cloned using Kamonian technology and mass produced, for the Grand Army Of the Republic.
What genetic variations would you look for in comparing sunflowers?
Your breeding would be crossing those specimens that are both shorter and have more red color.
Scientists thought genetic material was a protein not DNA because there are 20 different amino acids for a building of a protein polymer, while DNA polymers only have 4 nucleotide bases.
