2 mar 2012 · This document discusses the structure, properties, and functions of DNA. It describes DNA as a polymer composed of deoxyribonucleotides that carries the genetic information found in chromosomes, mitochondria, and chloroplasts.
28 lis 2015 · The document summarizes the structure of DNA. It describes that DNA is composed of four nucleotides - adenine, guanine, cytosine, and thymine. These nucleotides are linked by phosphodiester bonds to form a double helix structure.
20 lut 2019 · The primary function of DNA is to serve as the template for its own replication and transcription into RNA to direct protein synthesis. DNA is a double-stranded molecule that forms a helical structure. It is composed of nucleotides, each containing a phosphate group, deoxyribose sugar, and a nitrogenous base.
1 sie 2014 · Structure of DNA – Levels of Complexity • Nucleotides = building blocks • Strand = covalently linked nucleotides in a linear fashion • Double helix = two strands twisted together • Chromosome = association of DNA with proteins to organize strands into a compact structure • Genome = complete complement of an organism’s genetic material
17 lis 2014 · hybrid dna-rna structures • these assume the a-like conformation • usually short sequences • examples: • dna synthesis is initiated by rna “primers” • dna is the template for transcription to rna
The document summarizes key concepts about DNA structure and function including: 1. DNA replicates in a semi-conservative manner where each new DNA molecule contains one old and one new strand. 2. DNA replication requires a DNA template, nucleotides, DNA polymerase, and energy.
19 paź 2010 · DNA is composed of 2 chains of nucleotides that form a double helix shape. The two strands are antiparallel. The backbone of the DNA molecule is composed of alternating phosphate groups and sugars. The complimentary nitrogenous bases form hydrogen bonds between the strands.
