BSC 1005 Exam #2 questions with 100%
complete solutions to pass
DNA has the capacity to - correct answer ✔✔store genetic information, copy it, and pass it from
one generation to the other generation.
Chromatin is - correct answer ✔✔DNA and proteins
Nucleic acids - correct answer ✔✔DNA and RNA; consist of long chains of nucleotides.
Therefore nucleotides are monomers and nucleic acids are polymers.
DNA is double stranded while - correct answer ✔✔RNA is single stranded.
Each nucleotide consists of 3 main parts; - correct answer ✔✔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 - correct answer ✔✔Adenine and Guanine
Pyrimidines - correct answer ✔✔Cytosine and Thymine
Purines and Pyrimidines are connected by - correct answer ✔✔a hydrogen bond.
Adenine is to _ as Cytosine is to _. - correct answer ✔✔Thymine; Guanine
In RNA, Thymine is replaced by - correct answer ✔✔Uracil.
, It is the order of these bases in a nucleic acid - correct answer ✔✔that specifies genetic
information.
Small hydroxyl groups hang from - correct answer ✔✔the sugar portion of the nucleotide.
DNAs have one less - correct answer ✔✔O (H & OH), hence the name Deoxy ribose, than RNA.
RNA has two - correct answer ✔✔OH groups.
In cells, each DNA molecule is organized as - correct answer ✔✔a chromosome.
A chromosome - correct answer ✔✔consists of DNA and adssociated proteins, carries a cell' s
genetic info.
Genome (chromatin) - correct answer ✔✔entire DNA center of the cell.
Rungs of DNA are made of - correct answer ✔✔nitrogen bases connected by hydrogen bonds.
James Watson and Francis Crick - correct answer ✔✔won the Nobel prize for their 3D double
helix model of DNA molecule.
DNA contains - correct answer ✔✔anti-parallel strands; oriented but in different directions.
Hydrogen bond sticks strands together and - correct answer ✔✔breaks when replicating.
