Lesson 2: DNA And RNA Structures Flashcards
1
Q
RNA
A
Ribonucleic acid, it is a nucleic acid used in protein synthesis
2
Q
Three structural differences between RNA and DNA
A
- Sugar
- Nitrogenous Base
- Strand
3
Q
Sugar
A
RNA nucleotides contain the sugar ribose instead of the deoxyribose
4
Q
Nitrogenous Base
A
RNA nucleotides contain the base uracil (U), not thymine
5
Q
Strand
A
RNA molecules are single stranded
6
Q
Messenger RNA (mRNA)
A
A type of RNA that carries copies of sequences of DNA from the nucleus to the cytoplasm for protein synthesis
7
Q
ribosomal RNA (rRNA)
A
A type of RNA, and works together with other proteins to form the structure of ribosome which coordinates the assembly of proteins.
8
Q
Transfer RNA (tRNA)
A
RNA molecule that carries amino acids to the ribosomes where they can be used in protein synthesis
