Answer:
Almost all of the cells in your body share the same DNA as was found in that first cell. Eyes and heart are so different because different set of problems are made in the various eyes and heart cell
Explanation:
a
both species had growth in number within the same time period
Answer:
One band of light density and one band of heavy density.
Explanation:
According to conservative model of replication, the original strands do not separate from each other during replication. Hence, after replication the old strands are together and the new strands are together.
Here, cells were grown in 14N medium first so 14N was used for DNA replication and all DNA molecules had 14N. When the cells were transferred to 15N medium, only 15N was available for replication process. New DNA molecules would be synthesised using 15N (15N15N) and old DNA molecules have 14N (14N14N). Hence, in density gradient one band will be of light density (14N14N) and one band will be of heavy density (15N15N).
Answer:
The correct order is
Prophase l , Metaphase l, Anaphase I, Telophase l, Prophase ll, Metaphase II, Telophase ll / Cytokinesis ll
Explanation:
In Meiosis there are total two phases - Meiosis I and Meiosis II and each phase consists of total six sub phases which are as follows -
Meiosis I
1. Prophase I
2. Prometaphase I
3. Metaphase I
4. Anaphase I
5. Telophase I
6. Cytokinesis I
Meiosis II
1. Prophase II
2. Prometaphase II
3. Metaphase II
4. Anaphase II
5. Telophase II
6. Cytokinesis II
Hence the correct order is
Prophase l , Metaphase l, Anaphase I, Telophase l, Prophase ll, Metaphase II, Telophase ll / Cytokinesis ll
To identify people by DNA it is better to make copies of non-coding segments because they exhibit more variation than genes.
- The polymorphic sequences of non-coding DNA vary between individuals in humans.
- Variable number tandem repeats, or VNTRs, are created when DNA sequences are repeatedly replicated in the genome's non-coding regions.
- It is possible to create a person's genetic fingerprint by counting the amount of repeats, which varies between individuals.
- However, this non-coding DNA is used in criminal investigations by forensic experts.
- There are distinctive repeating patterns found inside this area of DNA that can be utilized to distinguish one person from another.
- Short tandem repeats (STRs) are a type of pattern that can be measured to determine a person's DNA profile.
