Ap Ch 17

Question 1

Gene expression

Answer 1

a process by which DNA directs protein synthesis, including two stages: translation and transcription

Question 2

Transcription

Answer 2

is the synthesis of RNA using information in DNA

Question 3

Messenger RNA(mRNA)

Answer 3

is the genetic material that gives instructions to make proteins and is the product of transcription

Question 4

Translation

Answer 4

is the synthesis of a polypeptide bond, using information in the mRNA

Question 5

Ribosomes

Answer 5

organelles in the cell where the site translation takes place

Question 6

prokaryotes

Answer 6

organisms that are bacteria, translation of mRNA can begin before transcription has finished

Question 7

eukaryotic

Answer 7

organisms that have linear DNA, the nuclear envelope separates transcription from translation

Question 8

primary transcript

Answer 8

is the initial RNA transcript from any gene before prossecing

Question 9

Central Dogma

Answer 9

is the concept of cell going to the process DNA-RNA-protein

Question 10

What are the two types of secondary structure?

Answer 10

Alpha helix and beta pleated sheets

Question 11

polypeptide

Answer 11

the bonds in amino acids that make proteins and there are three structures

Question 12

Codon

Answer 12

is the three nucleotide sequence in mRNA

Question 13

Anticodon

Answer 13

is the three nucleotide sequence in tRNA

Question 14

Triplet code

Answer 14

a series of nonoverlapping, three-nucleotide words

Question 15

Methionine

Answer 15

is the amino acid that starts synthesis of protein.

Question 16

AUG

Answer 16

is the section that methionine is found in a codon chart

Question 17

Reading Frame

Answer 17

reading left to right in triplets

Question 18
