4-5-2 Protein Synthesis: RNA

Question 1

Protein Synthesis

Answer 1

Process by which Protein is made

Question 2

Is protein made directly from DNA

Answer 2

No

Question 3

3 differences between DNA and RNA

Answer 3

(1) DNA is double strand, RNA is single strand. (2) The sugar in DNA is Deoxyribose, but in RNA, its Ribose. (3) RNA uses Uracil (U) rather than Thymine (T).

Question 4

RNA

Answer 4

Ribonucleic Acid

Question 5

Where in the cell do you find RNA

Answer 5

(1) the nucleus, (2) the cytoplasm, (3) ribosomes

Question 6

Components of Ribosomes

Answer 6

(1) two-thirds ribosomal RNA (rRNA) and (2) one-third protein.

Question 7

The central dogma

Answer 7

information flow is from DNA to RNA to protein. (or in other words, you start with DNA, then RNA is made from the plan in the DNA, then protein is made from the plan in RNA

Question 8

Who proposed the Central Dogma

Answer 8

Francis Crick

Question 9

Transcription

Answer 9

the construction of an RNA molecule from a DNA template.

Question 10

Translation

Answer 10

is the building of an amino acid sequence (a polypeptide) from the plan in an RNA molecule.

Question 11

Evidence that RNA is involved in protein synthesis

Answer 11

If RNA extracted from a virus was injected into a host cell, the cell began to make new viruses.

Question 12

mRNA

Answer 12

Messenger RNA (mRNA) is the blueprint for construction of a protein.

Question 13

rRNA

Answer 13

Ribosomal RNA (rRNA) is the construction site where the protein is made.

Question 14

tRNA

Answer 14

Transfer RNA (tRNA) is the truck delivering the proper amino acid to the site at the right time.

Question 15

Three kinds of RNA

Answer 15

mRNA, rRNA, tRNA
