3.DNA that provides instructions for building a proteina variant of a gene

4.DNA of no known function

5.The genetic composition that underlies a trait (or traits)

6.A single molecule of DNA & its associated "helper" molecules

7.The portion of DNA that controls when and where proteins are synthesized

Question 2: Fill in the blank with these terms: dependent variable, independent variable, y-axis, x-axis

Understanding graphs is an important skill in science, since being able to visually depict data is often useful for identifying patterns, and can sometimes be the only tool for easily evaluating whether or not the data supports your hypothesis. When viewing a graph, the______ is plotted on the______, and the______we are measuring is plotted on the_____. For example, in one of the photosynthesis experiments last week, temperature was the______, while the size of the bubble at the end of the experiment was the_____

Question 3: For each of the following terms, select the best definition:

diploid cell, haploid cell, fertilization, zygote, gamete, somatic cell

1. The merging of two gametes

2. Any cell in an organism, except those used for reproduction

3. A cell with only one copy of each gene

4. The process of cell division

5. The cells used for sexual reproduction (generally eggs & sperm)

6. The initial cell of an organism

7. A cell that is capable of differentiating into multiple types of specialized cells

8. A cell with two copies of each gene

Explanation / Answer

Q 1

Gene : DNA that provide instructions for synthesizing various types of RNA molecules.

Phenotype: DNA of no known function

Chromosome: A single molecule of DNA and its associated helper molecules.

Genotype :Genetic composition that underlies a trait

Alleles : DNA that provides instructions for building a protein varient of a gene.

Genome : complete set of genetic material in a cell of an organisms.

Q 2. when viewing a graph, independent variable is plotted on the X-axis, and the Dependent Variable we are measuring, is plotted on the y- axis. for example, in one of the photosynthesis experiment, Temperature was the independent variable while size of the bubble at the end of the experiment was the dependent variable.

Q3. Diploid cells: A cell with two copies of each gene

Haploid Cells: A cell with only one copy of gene

Fertilization: Merging of two gametes

zygote: The initial cell of an organism

Gamete: The cells used for sexual reproduction (generally eggs and sperm)

Somatic Cells : Any cell in organisms except those for reproduction
