CHAPTER 1 (GENE EXPRESSION)

Question 1

whats gene expression

Answer 1

process where the information in a gene is read and used to synthesize a protein

Genetic information is linearly transferred from DNA to protein.

Question 2

what proteins u can make depends on___

Answer 2

___what genes you have

Question 3

DNA -> ___ -> _____

Answer 3

DNA -> RNA -> Protein

Question 4

what is
1. transcription
2. translation

Answer 4

1. transcription: The process of making RNA from a DNA template.
2. translation: The process of making a protein from an mRNA template.

Question 5

whats reverse transcription

Answer 5

The transfer of genetic information from RNA to DNA by the enzyme reverse transcriptase found in retrovirus

Question 6

why do we need reverse transcription

Answer 6

it allows us to make cDNA (complementary DNA) from mRNA and obtain a gene sequence without the introns

Question 7

whats introns and exons

Answer 7

introns - non coding regions of the gene
exons - coding region of the gene (they stay and expressed)

Question 8

what is gene expression of eukaryotes gene into bacteria means?

Answer 8

refers to the process of transferring a gene from a eukaryotic organism (like a human or plant) into bacterial cells (such as E. coli) and then getting the bacteria to produce the protein encoded by that gene.
