CONCEPTS

◉ mRNA (Messenger RNA). Answer: Carries genetic information
from DNA to the ribosome for protein synthesis.


◉ rRNA (Ribosomal RNA). Answer: Structural component of
ribosomes that helps assemble proteins.


◉ tRNA (Transfer RNA). Answer: Transfers amino acids to
ribosomes during protein synthesis.


◉ Ribosome. Answer: Molecular machine that synthesizes proteins
using mRNA and tRNA.


◉ Codon. Answer: A sequence of three mRNA nucleotides that codes
for a specific amino acid.


◉ Anti-codon. Answer: A sequence of three tRNA nucleotides that
pairs with a codon on mRNA.

, ◉ Transcription. Answer: The process of copying DNA into mRNA.


◉ Translation. Answer: The process where ribosomes use mRNA to
build proteins.


◉ Mutation. Answer: A change in DNA sequence that may affect gene
function.


◉ Substitution. Answer: A mutation where one nucleotide is
replaced with another.


◉ Insertion. Answer: A mutation where an extra nucleotide is added
to the DNA sequence.


◉ Deletion. Answer: A mutation where a nucleotide is removed from
the DNA sequence.


◉ Frameshift. Answer: A mutation caused by insertion or deletion
that shifts the reading frame.


◉ Allele. Answer: A different form of a gene.


◉ Dominant. Answer: An allele that shows its trait even if only one
copy is present.
