Researchers have proposed that early life on Earth used RNA as its source of genetic information and that DNA eventually replaced RNA as the source of genetic information. What aspects of DNA structure might make it better suited than RNA to be the genetic material?

A DNA helix is found in the _____ form while an RNA helix is found in the _____ form. A) A, B B) B, A C) C, D D) Right, Left

DNA can be unwound from the double stranded double helix into single strands, amplified, separated on gels by size, stained with dyes.  It can be mutated by a variety of means.  It can be sequenced. Describe one or more of the ways that scientists are able to manipulate DNA and relate this to the structure of the DNA.

Which of the following correctly describes the structure of DNA? strands of phosphate-nitrogen backbone, which complementary nitrogenous base pairs bound in a double helix strands of sugar-nitrogen backbone, with complementary deoxyribose base pairs bound in a double helix strands of phosphate-sugar backbone, with complementary nitrogenous base pairs bound in a double helix strands of phosphate-sugar backbone, with complementary nitrogenous base pairs bound in a single helix

What forms the basis of tetranucleotide hypothesis for DNA structure ?

Watson and Crick used scientific reasoning, their knowledge of biochemistry, and the research of other scientists to make one of the most important scientific claims of their time: DNA is a double helix with strands running in opposite directions. Between these strands, A pairs with T, and C pairs with G.

Shown below is a DNA coding strand. A base (*G*) mutates to Adenine (A). What will be the resulting amino acid sequence as a result of the mutation? What type of mutation occured? Hint: Determine the template, then first determine the amino acid sequence before the mutation, and then determine the amino acid sequence after the mutation. Show how you got your answer. 5' T-A-C-T-T-C-C-A-*G*-C-C-G-C-T-C 3'

Is the structure of Human DNA same as the Bacteria DNA?

Construct an explanation based on evidence for how the structure of DNA determines the structure of proteins which carry out the essential functions of life through systems of specialized cells.
