Explain what the central dogma of molecular biology is
It explains the flow of genetic information within the biological system the idea that:
DNA makes rna and rna makes proteins
What is the biochemical definition of a gene
Unit of heredity
Stretch of chromosomal material that influences an organisms traits
Stretch of DNA or RNA that either codes for a proteins or acts as a template for a functional chain of RNA.
Which strand of dna is transcribed
The template strand is transcribed in the 3’-5’ direction and the rna produced is in the 5’-3’ direction the non transcribed strand is called the coding strand
How does rna differ from dna
Rna is a single strand of nucleotides
What is a promoter
A nucleotide sequence in the dna with rna polymerase binds to begin transcription.
