Answer:

1. Sex chromosomes.

2. Genotype.

3. Allele.

4. Meiosis.

5. Gametes.

6. Genome.

7. Mitosis.

8. Homologous Chromosomes.

9. Crossing over.

10. Gremlins cells.

11. Zygote.

12. Somatic cells.

13. Independent assortment.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Heredity refers to the transfer of traits (specific characteristics) from the parent of a living organism to her offspring through sexual reproduction or asexual production. Some examples of hereditary traits are dimples, tongue rolling, baldness, handedness, freckles, curly hair, color blindness, height, etc.

The various terminologies used in the field of genetics includes;

1. Sex chromosomes: The chromosomes that determine your biological sex -X and Y.

2. Genotype: The set of alleles an organism inherits.

3. Allele: Versions of a gene that arise through mutation.

4. Meiosis: Cell divisions that occurs in sex cells.

5. Gametes: Egg and sperm cells.

6. Genome: The complete set of genes in an organism.

7. Mitosis: Cell division that occurs in all body cells.

8. Homologous Chromosomes: The matching chromosomes a person inherits from their mother and father.

9. Crossing over: A process that increases genetic diversity during meiosis.

10. Gremlins cells: Cells that divide to produce gametes.

11. Zygote: The cell formed when an egg and sperm meet

12. Somatic cells: Body cells (hair, skin, brain, bone, etc.)

13. Independent assortment: The random lining-up of homologous pairs at the cell's middle.

Information stored _____ must be translated into functional products.
elena-14-01-66 [18.8K]

Answer: Information stored in DNA must be translated into functional products.

Explanation: DNA is a short form of deoxyribonucleic acid. DNA is a type of nucleic acid. There are two types of nucleic acids: DNA and RNA (ribonucleic acid).

DNA is a double-stranded helical molecule that contains the complete information for the synthesis of a functional gene product. The functional gene product is usually a protein.

DNA is first copied into a messenger RNA (mRNA) in a process known as transcription. This process is catalyzed by the enzyme RNA polymerase. This process occurs in the nucleus.

The mRNA leaves the nucleus to the ribosome where it is used to produce a protein. This process is called translation and occurs in the ribosome. The protein is the functional product that expresses its function in the organism.
