It is Fungi. All the other ones are unicellular
Nucleotides play different roles such as being the building blocks of nucleic acids, energy storage, cellular signaling, enzymatic cofactors, etc.
- Nucleotides are the building blocks of nucleic acids (either DNA or RNA).
- These molecules (nucleotides) are composed of one pentose sugar, a nitrogenous base, and one or more phosphate groups.
- In DNA, there are four types of nucleotides, each containing one different nitrogenous base (i.e., Adenine, Guanine, Cytosine and Thymine).
- Adenosine triphosphate (ATP) is a nucleotide that represents the energy coin of the cell, which is used to carry out different metabolic functions (e.g., growth, differentiation, reproduction, etc).
In conclusion, nucleotides play different roles such as being the building blocks of nucleic acids, energy storage, cellular signaling, enzymatic cofactors, etc.

DNA replication follows the base pairing rule (A with T and G with C). This ensures identical replication of the genetic information; hence it's conservation. Each daughter DNA double helix contains one old strand of DNA and one newly-synthesized strand of DNA. This is known as the semi-conservative mechanism.
DNA replication also occurs during mitosis which produces haploid gametes. Each parent contributes half of the genetic information during fertilization of two gametes, thus regenerating the diploid number. Genes from both parents are transmitted to the offspring.
