UNIT 3 2A: Nucleic Acids Flashcards
1
Q
Polymer
A
A molecule made up of a large number of smaller, repeating units
2
Q
Monomer
A
A molecule that forms bonds with other identical molecules as the repeating units that make up a polymer
3
Q
Nucleotide
A
The monomer of nucleic acids which are joined together to form DNA or RNA
4
Q
Parts of a Nucleotide
A
Phosphate group
Sugar
Nitrogenous base
5
Q
What is Messenger RNA
A
Carries the genetic information from regions of DNA to be used to synthesize proteins
6
Q
Ribosomal RNA (rRNA)
A
The main component of ribosomes. Ribosomes are the organelles responsible for protein synthesis within a cell.
7
Q
tRNA
A
Involved with delivering and linking amino acids during protein synthesis
8
Q
Differences between RNA and DNA
A
- DNA has the sugar Deoxyribose, whereas RNA has the sugar ribose
2. DNA is double-stranded, whereas RNA is single-stranded
3. DNA contains the nitrogenous base Thymine, wheres RNA contains the Nitrogenous base Uracil
