Answer:

Step one: After pollen has landed on the stigma, it grows a pollen tube down through the style to the ovary. Step two: The nucleus of the pollen grain travels down the pollen tube and fertilises the nucleus in the ovule. Step three: The fertilised ovule develops into a seed.

What is the complementary RNA sequence for the following segment of DNA? ACC TAG CGA Question 6 options: ACC TAG CGA UGG AUC GCU

RUDIKE [14]

RNA is a single-stranded molecule, which is made up of similar composition as DNA. RNA differs from DNA in the nitrogenous base as it has uracil in place of thymine.

<h3>What is the complementary RNA sequence?</h3>

A complementary sequence refers to the copy of the strand or template strand of the RNA. The complementary strand will be the copy of the original strand.

In the complementary base pairing, guanine will be complementary to cytosine and adenine to uracil.

In the given sequence of RNA, ACC TAG CGA, the complementary sequence formed will be UGG AUC GCU.

Thus, the complementary sequence will be UGG AUC GCU.
