only one strand of the molecule acts as a template

both strands of a molecule act as templates

the reaction is catalyzed by RNA polymerase

the cell undergoes mitosis

errors never occur

its helical nature and hydrogen bonding

its specific sequence of bases

its deoxyribose sugar and phosphate groups

its specific base pairing through hydrogen bonds

its phosphodiester linkages and complementary strands

All of the listed responses are correct.

the variation in the structure of nucleotides that make up the DNA molecule

the types of sugars used in making the DNA molecule

the sequence of nucleotides along the length of the two strands of the DNA molecule

Adenine forms two covalent bonds with thymine; guanine forms three covalent bonds with cytosine.

Adenine forms three covalent bonds with thymine; guanine forms two covalent bonds with cytosine.

Adenine forms three hydrogen bonds with thymine; guanine forms two hydrogen bonds with cytosine.

Adenine forms two hydrogen bonds with thymine; guanine forms three hydrogen bonds with cytosine.

Adenine forms two hydrogen bonds with guanine; thymine forms three hydrogen bonds with cytosine.

adenine and cytosine ... guanine and thymine

cytosine and thymine ... adenine and guanine

adenine and thymine ... cytosine and guanine

adenine and guanine ... cytosine and thymine

A + T = G + C

the ratio of A to C is close to 1:1 and the ratio of G to T is close to 1:1

the ratio of A to G is close to 1:1 and the ratio of T to C is close to 1:1

the ratio of A to T is close to 1:1 and the ratio of G to C is close to 1:1

A + T = 50% of the total bases

fatty acids

disaccharides

nucleotides

amino acids

monosaccharides

proteins because they were thought to be the only molecule with both the variety and specificity of function to account for the array of heritable traits observed

carbohydrates because they are found in abundance in all organisms

amino acids because of all the ways they can join together

sterols because of the different variations on their ring structure

nucleoside triphosphates because of the ability to add and remove phosphate groups

genes are on chromosomes

the genetic material of the phage is DNA

bacteriophages can infect bacteria

the genetic material of the phage is protein

DNA is made of nucleotides

uses three bases to code for one amino acid

was the substance that transformed the bacteria in Griffith's experiment

has two strands held together with hydrogen bonds

contains adenine, guanine, thymine, and cytosine
