Which of the following statements about dna structure is true? view available hint(s) which of the following statements about dna structure is true? the nucleic acid strands in a dna molecule are oriented antiparallel to each other, meaning they run in opposite directions. hydrogen bonds formed between the sugar‑phosphate backbones of the two dna chains to stabilize dna structure. nucleic acids are formed through phosphodiester bonds that link nucleosides together. the pentose sugar in dna is ribose.

The correct answer will be option- the nucleic acid strands in a DNA molecule are oriented antiparallel to each other, meaning they run in opposite directions.

Explanation:

Deoxyribose nucleic acid or DNA is the molecule which acts as the genetic material of the organisms.

The structure of DNA suggests that DNA molecule is made of two strands of nucleotides which are oriented in the opposite direction with respect to each other.

Each nucleotide is composed  of a five-carbon sugar called deoxyribose bonded with a phosphate group via ester bond and four types of nitrogenous bases bonded to complementary bases via hydrogen bond.

The sugar-phosphate backbone runs in the opposite direction with a free 5' carbon atom of phosphate group end a 3' OH group of sugar. The orientation of strands is that one strand run from 5' to 3' direction while another runs from 3' to 5' direction.

Thus, the selected option is the correct answer.

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community

explanation:

the answers are as following:

1. c. double helix, nucleosome, coil, supercoil, chromosome

2. b. g2 phase, preparation for mitosis

3. d. interphase consists of the g1, s, and g2 phases

4. c. metaphase

5. a. chromosomes are duplicated before cell division so that each new daughter cell has a complete set
