Chromatin is when ever something is caused by ? | The granular material visible within the nucleus; consists of DNA tightly coiled around proteins. |
Molecular Genetics is the study of ? | The agents that pass information from generation to generation. |
What do genes determine ? | They determine the heredity traits. |
Many disease are caused by ? | Mutations or changes in the DNA sequence. |
Molecular genetics also refers to or sometimes introduced to ? | a fundamental theory alleging that genes direct all life process through the production of polypeptides. |
Is the stage where opposite chromosomes are moved to the end spindles are ? | Anaphase. |
The process where genetics diseases get more severe in each successive generation are ? | Is the anticipation. |
Is a mutation resulting in the loss of normal DNA sequence is ? | A deletion. |
conversion from double stranded to single stranded form, often by heating sometimes by treatment with alkali ? | Denaturation. |
