New video posted: Translation - making proteins from DNA - decoding mRNA to make the protein

This is the second of two videos on how cells make proteins using DNA. In the first video, I looked at the first step, which is making the messenger RNA (mRNA) a process called transcription - Transcription - making proteins from DNA - the mRNA.

In this video, I will guide you through the process of producing the protein from the mRNA, also known as translation. I will look at the coding problem (how many mRNA bases do you need to code from an amino acid), the number of reading frames in a DNA molecule, and how the cell produces protein from the mRNA.

Single letter amino acid codes

The amino acids have single and three-letter codes, and these are worth learning for your degree.

Remembering the single-letter amino acid codes is a breeze. In most cases, it's just the first letter of the amino acid's name.

AAlaAlanine
CCysCysteine
GGlyGlycine
HHisHistidine
IIleIsoleucine
LLeuLeucine
MMetMethionine
PProProline
SSerSerine
TThrThreonine
VValValine

However, in 9 cases it is not the first letter:

DAspAspartate
EGluGlutamate
FPhePhenylalanine
KLysLysine
NAsnAsparagine
QGlnGlutamine
RArgArginine
WTrpTryptophan
YTyrTyrosine
