dna replication

Question 1

What do we know about proteins?

Answer 1

that they’re not THE genetic material

Question 2

What two types of proteins are there?

Answer 2

structural proteins and enzymes

Question 3

What are the two enzymes essential in DNA replication?

Answer 3

helicase- unzips DNA
DNA polymerase- lays down nucleotides

Question 4

What do we know about DNA?

Answer 4

-stores blueprint required to produce organism
- %A=%T, %G=%C
- DNA is copied/ passed down from gen to gen (can be the same or only sim due to genetic mutations)

Question 5

What is the process of the central dogma?

Answer 5

DNA- RNA- proteins

Question 6

What are the differences between DNA and RNA?

Answer 6

DNA
- double helix
-ACTG
-large
-nucleus
-missing o group

RNA
- single strand
-AUCG
-smaller
-travel b/t nucleus and cyto

Question 7

What is transcription?

Answer 7

-conversion from 1 form of smth to another
-DNA to mRNA

Question 8

what is translation?

Answer 8

-conversion to a diff “language”
- mRNA to tRNA

Question 9

Describe transcription from DNA to mRNA

Answer 9

helicase unzips DNA -> promoter region in the DNA tells RNA polymerase where to go-> RNA polymerase keeps it open, reading the template and making a complementary strand-> runs into terminator region causing RNA polymerase to fall off and go to cyto

Question 10

Describe the post transcription.

Answer 10

pre-mRNA-> mRNA
introns (non-coding regions) are spliced by enzymes and exons are joined together

Question 11

describe translation.

Answer 11

mRNA->RNA
tRNA matches anti-codon with codon region of mRNA
enters P and A site, P site matches, P site kicked out
