The answer is 1. Hereditary information is located in genes found in chromosomes. This chromosome is a thread like structure which is coiled tightly and is supported by histones.

The answer is 3. DNA deletion is a type of mutation wherein genes are removed in the sequence during DNA replication. This is often caused by certain mutations occurring during replication.

The answer is 1. Gene splicing is when a single gene can code for two or more proteins. This process is done before translating mRNA by including or excluding proteins.

The answer is 1. DNA mutations are mistakes or alterations formed in a DNA sequence which can be a result of adding, removing or substituting the original or specified DNA molecule.

The answer is 1. Genetic engineering has been of great help in our community. This is because various forms or types of living organisms are formed in order for us to meet our demands.

The answer is 2. A DNA is double stranded with two polynucleotide chain which consists of a phosphate, a sugar and a nitrogen base. Adenine always pairs with thymine and guanine with cytosine.

The answer is 1. In order for DNA to undergo cell division, the bases must be divided in order for new base pairs to combine thus making the strand long.

The answer is 1. Cloning is the process of replicating genes in order to produce an identical type of plant or organism. Even though they are the same, they still have different DNA inside them.

According to the given data, we can therefore conclude that beta carotene decreases the amount or prevalence of mutated cells in the body. This is shown by the decreasing trend of the line graph in the data shown.

This is not a valid conclusion. There is no evidence to support regarding vitamin E. If they have the same property, vitamin E would most like decrease also the amount of mutated cells in the body of the rat.

Proteins are macromolecules composed of nucleic acids residues which is the component of DNA. These nucleic acid residues come in long chains and do most of the work inside cells. Proteins can function as structural materials, energy sources and chemical messengers. These proteins are made inside ribosomes.

A bacterial plasmid is circular, small and double stranded molecule that can be unique inside a cell. Plasmids carry or transport DNA which contain genes usually for antibiotic resistance.

aA hybrid plasmid is a plasmid but with human DNA or any other foreign DNA.

Genetic engineers use specialized techniques in performing splicing. The usage of enzymes for cutting DNA and inserting it into another organism’s DNA into its plasmid is done.

One benefit of splicing is the ability of the newly spliced individual to be able to produce or manufacture the hormone deficient in his or her body without the need of other supplements.

It is not necessary to continue splicing the gene for human growth hormone once cultures of the bacteria with the spliced gene are established because once human and bacterial DNA have already interchanged, they will continue to reproduce and the DNA will be incorporated for every new cell made.

Artificial selection or selective breeding is the process wherein certain DNA is copied to reproduce a similar without the process of sexual reproduction. But this reproduction is artificially mated to produce the same organism.

Selective breeding would be used to improve the racing ability of horses by artificially breeding champ lines which have the genes specifically for racing. This can be acquired by artificially breeding two champ lines of horses and producing an offspring with it.

A disadvantage of producing an offspring by using natural selection or selective breeding would be the chance of having mutated genes causing an unfavorable offspring.

Knowledge on human genes have been a great help in the current state of the human race. Since there are a lot of mutations nowadays due to various effects of the environment, there are a lot of studies used to prevent them as well as produce the deficiencies needed in an individual.

One specific concern would be the early identification of mutations occurring in an individual. Before the mutation is expressed, early identification and alteration could be done in order to correct the wrong coding.

This can be done by doing artificial selection or selective breeding. It is the process wherein certain DNA is copied to reproduce a similar without the process of sexual reproduction. But this reproduction is artificially mated to produce the same modified organism.

Multiplying this type of plant for future supply can be done by cloning. Cloning is the process of replicating genes in order to produce an identical type of plant or organism. Even though they are the same, they still have different DNA inside them.

Altering mainly the chicken will be easier because once the DNA is altered, the replication of cells will carry the modified cell in all products but when only the protein is altered, there is a need to alter every protein produced.

Recombinant DNA is the one responsible for cutting and inserting the modified DNA into an organism in order to be expressed. This will create different coding sequences according to the desired modification.

One advantage of using chicken instead of other animals is the cost. Chickens are not that expensive compared to other animals.

One reason why people may be against this is because some people believe that altering genes or modifying it will alter the normal or natural state of the animal thereby deeming it artificial and can be believed to have hazardous effects in health.

Artificial selection or selective breeding is the process wherein certain DNA is copied to reproduce a similar without the process of sexual reproduction. But this reproduction is artificially mated to produce the same organism. Cross breeding the two plants would create a resistance for the wheat plant according to their desired trait.
