The mutagens that result in cancer damage DNA by (b) weakening the DNA strand or interfering with base pairing. This mutagens are called carcinogens, if they cause a damage to <span>a gene that makes a </span>DNA<span> repair protein, it means that a cell will have less ability to repair itself, and ,as a result, this will lead to formation of cancer.</span>
Answer:
1. DNA sequence
Since DNA is passed from parents to offspring, it is the most accurate way of
determining evolutionary relationships between species.
2. eukaryotic
3. protists and plants
4. species F/6
All the above is correct.
Answer:
The disadvantages of the given instance are mentioned below.
Explanation:
This analysis seems to be a tool device used to evaluate the proportion of the population.
<u>Disadvantages:</u>
- The effectiveness is dependent on a significant portion of the number of people is being recorded.
- Animal marks may have a drastic impact on either the animals.
- This approach does indeed have a certain drawback because that's not a very suitable technique.
The answer is d. deletion.
If the DNA sequence is TTCACG, it is expected to be transcribed into AAGUGC.
But, it was transcribed into AAGGC. If we count nucleobases, a transcribed sequence has 5 nucleobases, while DNA sequence has 6 nucleobases. These means that deletion happened.
If insertion occurred, there will be 7 nucleobases in transcribed sequence. In substitution or translocation, the transcribed sequence will be the same size, but with different sequence than the DNA sequence.
