The initiation of DNA replication<span> occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the </span>DNA<span> double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the </span>DNA<span> strands, thereby pulling apart the two strands.</span>
Answer:
<em>False</em>
Explanation:
The wax acts as a sealant to reduce the stress on the roses during transit and up until the time they can be planted and established into ground soil.
Given that,
Density of the liquid, d = 3 g/ml
Volume, V = 20 mL
To find,
The mass of the liquid.
Solution,
The density of an object is given by its mass divided by volume such that,
d = m/V
m is mass
m = d×V
Put all the values,
m = 3 g/mL × 20 mL
= 60 grams
Hence, the mass of a liquid is 60 grams.
The correct option for given statement is
D
I and II only
I. Enzymes are not consumed during a chemical reaction.
II. Enzymes are specific to particular molecules
Explanation:
Enzymes are biological molecules (typically proteins) that considerably speed up the speed of nearly all of the chemical reactions that turn up at intervals cells.They're necessary|important} always and serve a large vary of important functions within the body, like aiding in digestion and metabolism.
