Answer:

Sister chromatids. (Ans. B)

Explanation:

Sister chromatids are defined as the identical chromatids formed by the DNA replication of the chromosome, both copies of chromatids are joint together by a centromere. A pair of chromatids are known as dyad.

A set of sister chromatids formed during the S phase or synthesis phase of interphase, while all the chromosomes present in a cell is replicated. During the process of mitosis, or second division of meiosis the two sister chromatids are gets separated from each other into two different daughter cells, and each cell receives one copy of the chromosomes.

Stels [109]

EXPLANATION:

There are 2 types of nucleic acids: DNA(deoxyribonucleic acid) and RNA(ribonucleic acid).

Living organisms have their genetic material in their DNA. Viruses use RNA as their genetic material but are usually called non-living things( because they can't reproduce without help from a host).

The function of nucleic acids has a progression from DNA to RNA to proteins. This is called the central dogma of molecular biology.

Nucleic acids are formed by a linkage of polynucleotide chains with phosphodiester bonds. These polynucleotide chains are formed from monomers called NUCLEOTIDES.

A nucleotide is made up of 3 parts:

i) a nitrogenous base

ii) a five-carbon sugar

iii) at least one phosphate group.

icang [17]
You did not included your list of selections.  Some general properties ascribed to DNA are storage and expression of information and variables through mutations.  Replication, Transcription, Translation and Mutagenesis are the major functions of DNA in a cell.  DNA nucleotides contain deoxyribose.  DNA is double-stranded in the conservative mode, the original double Helix remains a complete unit and the new DNA double Helix is produced as a single unit.  In the double=stranded DNA, Hydrogen bonds hold one complimentary strand to the other.  

Hope this helps, I love Science.
