What is a nucleotide? - ANSWER Nucleotides are the monomer units of
nucleic acids. They consist of a nitrogenous base, 5-carbon sugar, and a
phosphate group.
What is a biopolymer? - ANSWER A polymer produced by a living organism.
Nucleic acids are biopolymers of which type? - ANSWER DNA and RNA
What are the key characteristics of DNA? - ANSWER DNA carries genetic
information and is double-stranded, making it stable.
What are the key characteristics of RNA? - ANSWER RNA is less stable.
Most intermediate forms express genetic information and can build secondary
structures through hydrogen bonding (e.g., tRNA).
Usually single-stranded.
What are the different forms of RNA, and what do they do? - ANSWER The
following terms are used in biology: tRNA (transfer RNA), rRNA (ribosomal
RNA), and siRNA (small interfering RNA), which targets mRNA for
destruction and silences pleiotrophin-coding genes.
miRNA: microRNA, silencing and post-transcriptional regulation of gene
expression.
In contrast to DNA, RNA may catalyse processes and provide a wide range of
functions.
Why does inosine have real wobbling qualities? - ANSWER: If that is the first
nucleotide in the anticodon, any of the three bases in the original codon can be
matched with the tRNA.
What are the two types of nitrogenous bases? - ANSWER Purines &
Pyrimidines
