Answer:
a. 3′→5′ exonuclease activity = No proof reading
b. 5′→3′ exonuclease activity = No primer removal
c. 5′→3′ polymerase activity = No gap filling
Explanation:
<u>a) 3′→5′ exonuclease activity = No proof reading</u>
3′→5′ exonuclease activity of DNA polymerase I is responsible for proof reading so that if a wrong nucleotide is inserted during replication, it could be removed. So if a mutation will occur in the domain which is responsible for 3′→5′ exonuclease activity error prone DNA replication will occur.
<u>b. 5′→3′ exonuclease activity = No primer removal</u>
5′→3′ exonuclease activity is useful in removing primers so that appropriate nucleotides could be inserted in the lagging strand. But if mutation will occur in this part of DNA polymerase I then primer will not be removed and replication of lagging strand will be at halt.
<u>c. 5′→3′ polymerase activity = No gap filling</u>
5′→3′ polymerase activity of DNA polymerase I, joins the nucleotides in the lagging strand where the gaps have been created after removal of primer. So the gaps created after removal of primer in the lagging strand will not be filled if there will be a mutation in this segment of DNA polymerase I.
Add starch indicator solution to the water in the beaker. If the indicator solution changes color than starch is present.
Answer:
6 alleles.
Explanation:
Alleles may be defined as the alternative form of a single gene. The alleles are present on the same chromosome of a particular gene.
CTGT and TGTC are the two alleles of a given gene. Three single crossovers exist between the two alleles. the single crossover can produce two new allele so the three crossovers can produce six new alleles.
Thus, the correct answer is option (D).
Nuclear fusion is the answer of this question
Explanation:
1. What is a longitudinal wave?
- A wave vibrating in the direction of propagation
- This is also called "pressure waves"
- Example: Sound waves, ultrasound waves
2. When you hear a sound wave through the air, what are you detecting?
We are detecting the sound wave through the ears. There is a part called ear drum present inside the ear and it turn contains 3 bones which makes us to hear the sounds. When sound waves enters, the ear drum vibrates.
3. In which direction does the material vibrate, as energy travels through it?
The direction is perpendicular to the direction of energy transport.
4. When a wave transmits, or transfers, energy, do the individual molecules or particles also move from one end to the other?
Yes, the particles move from one end to other.
