nirvana33 [79]

Answer:

Due to different pigments.

Explanation:

The multicellular algae are red, green and brown because of the presence of pigments. The red algae are red in colour because of the presence of the phycoerythrin which is a type of pigment. This pigment reflects red light due to already presence in its body and absorbs blue light that is necessary for photosynthesis process. The brown algae contain fucoxanthin pigment and green algae contain xanthophylls pigments that are responsible for its colour so we can conclude that these different types of pigments are responsible for the different colour of algae.

Which molecule is active during the last step of DNA replication?
stepan [7]

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.
