DNA Flashcards

(27 cards)

1
Q

What was already known about genes or what do you know

A

That they code genetic information and that its a generational molecule/s being passed down. One gene- one polypeptide. Chromosomes were available

Q

What are phages

A

They are genetic material wrapped in protein. They are viruses that infect bacteria and use them to create more phage. Think about the influenza.

16
Q

what does the one gene and one enzyme have to do with mutations?

A

if an organism cannot convert one particular compund to another. It lacks enzyme required for the next step

17
Q

explain the central dogma

A

transcription and translation etc.

18
Q

protein synthesis isnt always like central dogma …

A

because of virus. sometimes RNA and code and then go into a polypeptide.

19
Q

EXPLAIN initiation, elongation and termination.

A

The promoter, the coding aka the continuation, the release

20
Q

What editing sequence is removed and which on stays

21
Q

Transcription details

A

Promoter,RNA polymerase, mRNA, 5cap and poly tail

22
Q

explain translation

A

RNA to PROTEIN. relies on gentic code. also think about APE system when making a polypeptide

23
Q

tRNA

A

anticodon and amino acid attachment site

24
Q

tRNA synthase

A

amino acids charged with ATP. phosphates and bind to their matching tRNA which fuels peptide bond formation.

25
A site, P site and E site
A site gets the ribosome then P site has the start codon and then E site has the release.
26
The rest of the process relies on cellular structures of the endomembrane system.
LUMEN, vesicles, packaging etc. But post translation has ... phosphate groups, adding sugar, cleaving polypeptides etc.
27
remember the 4 levels of protein structures.
primary secondary tertiary Quatendary
