transcription and translation

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.
