Answer:
1.99metres
Explanation:
Foot and inches are measurements of heights. A height measurement of 6’6 1/2" means I am 6 foot and 6.5 inches tall.
Firstly, we need to convert the foot and inches measurement to all foot.
Since 1 foot = 12 inches
Then, the 6.5 inches is 6.5/12
= 0.5416foot
We add this to the existing feet measurement, i.e. 6 foot + 0.5416 foot
= 6.5416 foot.
Hence, 6'6.5" means 6.5416'
Now, we convert the foot measurement to metres.
1 foot makes 30.48 cm
Since 100 cm makes 1 m
30.48 cm will be 30.48/100= 0.3048m
Hence, 1 foot = 0.3048m
6.5416 foot = 6.5416 × 0.3048 m
= 1.9938
Therefore, a height measurement of 6’6 1/2" is 1.99 metres tall.

Correct answer: Option D- DNA ligase
Explanation: In option A, thymine is a nucleotide, so it is present throughout the replication process, wherever it is required. It is added to the newly formed DNA. In option B, Helicase enzyme is active during initiation and elongation stage, as it facilitates the opening of the winded DNA strands. Option C is nucleotidase and it has no role in DNA replication. So, the correct answer is DNA ligase, which is option D.
The okazaki fragments formed during DNA replication are sealed at the end. And in this step, DNA ligase is used. It catalyzes the formation of phosphodiester bond between the nucleotides of okazaki fragments. So it is the last active molecule of the process.
