Answer:
condensation
Explanation:
The water cycle
evaporation--> condensation--> precipitation-->repeat
Answer:
Anaphase of meiosis II
Explanation:
I think you are asking during which phase of cell division sister chromatids are mostly likely to fail to separate properly, a phenomenon that can lead to genetic disease.
This is sometimes called non-disjunction, and it is most likely to occur in anaphase during meiosis II. During this stage, sister chromatids of the two daughter cells produced by meiosis 1 are separated and brought to opposite parts of the cell. If something goes wrong at this stage, the sister chromatids can fail to separate properly, meaning the daughter cells do not have the correct number of chromosomes (see attachment).
An example of such a genetic disorder is Down syndrome
Answer:
B. identifying the regions of human DNA that are transcribed into RNA
C. identifying the regions of human DNA that bind to proteins
D. analyzing the regions of human DNA that vary among individuals
Explanation:
The double helix structure of the deoxyribonucleic acid (DNA) molecule was characterized and published in April 1953 by Francis Crick and James Watson. Moreover, the Human Genome Project was a project aimed at completing mapping and sequencing of the human genome. This project was completed and published in April 2003. Nowadays, scientists are focused on identifying which genes are expressed (i.e., transcribed into RNA) in specific cell types/tissues. For this purpose, it is imperative 1-to identify the promoter and enhancer regions that bind to specific proteins (transcription factors) in order to activate gene expression, and 2-to understand how genetic variation is related to gene expression patterns in specific cell types and/or in response to specific environmental stimuli.
