What differs among DNA structures of different species?

weqwewe [10]

Answer:

D) the arrangement of the nucleotides within genes

Explanation:

De-oxy ribo nucleic acid that is basically a polymer of nucleotides. Nucleotides are composed of three basic units: a de-oxyribose sugar unit, a phosphate group and nitrogenous bases that can be Adenine, Gunanine, Thymine and Cytosine.Adenine always pairs with Thymine and Guanine always pairs with Cytosine.

This is a universal composition of DNA in each and every living organism. The genes are a segment of DNA that contain specific sequence of nucleotides and encode for a specific trait of organism such as height, weight, eye color etc. The sequence of nucleotides expresses the trait in the form of protein product during the process of Translation. The products of translation are amino acids and every amino acids encode for a specific protein in almost all living organisms.

So, what differs in the specie is the sequence of nucleotides in genes. Infact this is the nucleotide sequence which brings evolution in organism and organisms evolve to form new specie with the passage of time. One major cause of change in nucleotide sequence is mutations due to which the organisms change with time.

Suppose the sequence of nucleotide of specific gene in organism A is

AAGGGGAAATTT

However in other specie organism B of same specie is:

TAGGGGAAATTT

This means only mutation of one base changed the gene in organism B and also its product called protein.

Hope it help!

Hunt and her team designed an experiment to test her hypothesis about the effect of BPA on mice. They administered daily doses o

katovenus [111]

Answer and Explanation: The figure below shows the doses of BPA administered to the female mice over time.

An experiment is used to determine cause and effect among variables. When the research is for the impact of a treatment, researchers randomly separate individuals in two groups:

Control Group doesn't receive any treament or a placebo or a treatment whose outcome is already known;
Treatment Group receives the treatment;

For the female mice on the image below, in the First Group is not injected any dosage of BPA, so they are the control group, while the others are treatment group.

The variables in a experiment are classified as independents or dependents:

Independent Variable is the cause;
Dependent Variable is the effect;

For the BPA research, since it is the effect of BPA over time on the mice's cells it is being investigated, dosage of BPA is the independent variable and time is the dependent variable.
