A plant has lost its chlorophyll and leaves during evolution. Now it derives its nutrition from the host plant. Identify this plant among the following.

Read the following passage carefully.
Restriction enzyme
Restriction enzymes cut the strand of DNA a little away from the center of the palindrome sites, but between the same two bases on the opposite strands. This leaves single stranded portions at the ends. There are overhanging stretches called sticky ends on each strand. These are named so because they form hydrogen bonds with their complementary cut counterparts. This stickiness of the ends facilitates the action of the enzyme DNA ligase. The word palindromes refer to group of letters that forms the same words when read both forward and backward. Restriction endonucleases are used in genetic engineering as molecular scissors.
Which one of the following enzyme helps to join DNA?

If a pink flowered Snapdragon plant is crossed with a white flowered Snapdragon plant, what will be the phenotypic ratio of their progeny?
