Question 23

Name the DNA and describe it

Answer 23

It’s deoxyribonucleic acid and its a molecule made of 2 strands coiled to form a double helix

Question 31

Function of RNA

Answer 31

It takes information from DNA in the nucleus to the ribosomes for the synthesises of protien

Question 32

2 types of RNA

Answer 32

Messenger RNA mRNA Transfer RNA tRNA

Question 33

Function of mRNA?

Answer 33

Form a copy from the DNA code

Question 34

What is meant by transfer RNA

Answer 34

Carries amino acid to the ribosomes to form the protien

Question 35

What are the 2 stages of protien synthesis

Answer 35

Transcription Translation

Question 36

Describe the process of transcription

Answer 36

.Takes place at nucleus .Part of DNA double helix unwind and expose the bases along the strand .The sequence of bases of DNA is copied to mRNA molecule .The mRNA leaves the DNA and passes out of the nucleus to the cytoplasm

Question 37

Describe process of translation

Answer 37

.Translation takes place at the ribosomes .coded consist of sets of 3 bases in mRNA .mRNA attach to the ribosome .tRNA molecule with anticodon complementary to the codon on mRNA molecule carry its specific ammino.acid to ribosome .another tRNA bring along a second ammino acid .ammino acid bind together and process continues adding ammino acid to growing chain form polypeptide chain

Question 38

What are the 3 bases in mRNA call (triplets)?

Answer 38

Codon
