BSC 1005 Exam #2
DNA has the capacity to - Answers-store genetic information, copy it, and pass it from one generation to
the other generation.
Chromatin is - Answers-DNA and proteins
Nucleic acids - Answers-DNA and RNA; consist of long chains of nucleotides. Therefore nucleotides are
monomers and nucleic acids are polymers.
DNA is double stranded while - Answers-RNA is single stranded.
Each nucleotide consists of 3 main parts; - Answers-a nitrogenous base with a purine or pyrimidine, a
pentose sugar with 5 carbon atoms, and a phosphate group consisting of 1, 2, or 3 phosphate groups
attached to the carbon atom.
Purines - Answers-Adenine and Guanine
Pyrimidines - Answers-Cytosine and Thymine
Purines and Pyrimidines are connected by - Answers-a hydrogen bond.
Adenine is to _ as Cytosine is to _. - Answers-Thymine; Guanine
, In RNA, Thymine is replaced by - Answers-Uracil.
It is the order of these bases in a nucleic acid - Answers-that specifies genetic information.
Small hydroxyl groups hang from - Answers-the sugar portion of the nucleotide.
DNAs have one less - Answers-O (H & OH), hence the name Deoxy ribose, than RNA.
RNA has two - Answers-OH groups.
In cells, each DNA molecule is organized as - Answers-a chromosome.
A chromosome - Answers-consists of DNA and adssociated proteins, carries a cell' s genetic info.
Genome (chromatin) - Answers-entire DNA center of the cell.
Rungs of DNA are made of - Answers-nitrogen bases connected by hydrogen bonds.
James Watson and Francis Crick - Answers-won the Nobel prize for their 3D double helix model of DNA
molecule.
DNA contains - Answers-anti-parallel strands; oriented but in different directions.
Hydrogen bond sticks strands together and - Answers-breaks when replicating.

the other generation.
