24 de set. de 2018 · we look closely at the structure and chemistry of DNA in order to learn how its double-helical architecture allows information to be stored, duplicated, and accessed.
21 de abr. de 2015 · Abstract and Figures. The proposal of a double-helical structure for DNA over 60 years ago provided an eminently satisfying explanation for the heritability of genetic information.
Estrutura da molécula do DNA muda em função do ambiente e da sequência de bases: Grande maioria-DNA presentes nas células forma B (Watson e Crick)
Quais são as funções do DNA? •Replicação (duplicação): preservação da espécie por que é o material genético •Transcrição: síntese de RNA (splicing) •Tradução: síntese proteica
5 de jan. de 2000 · The Structural Conformations of DNA 1. The principle message of this lecture is that the structure of DNA is much more flexible than previously conceived. DNA is a highly flexible molecule that can undergo a series of transformations leading to many conformations with different biological functions. 2. The structure of DNA as ...
9 de out. de 2019 · Georgina Ferry. On 25 April 1953, James Watson and Francis Crick announced 1 in Nature that they “wish to suggest” a structure for DNA. In an article of just over a page, with one diagram (Fig....
DNA encodes information through the order, or sequence, of the nucleotides along each strand. Each base—A, C, T, or G—can be considered as a letter in a four-letter alphabet that spells out biological messages in the chemical structure of the DNA.
