Question 1

Part 1

Answer 1

A particular section of the double stranded helix structure of a DNA molecule unwinds, weak hydrogen bond break and the 2 strands unzip.

Question 2

Part 2

Answer 2

A particular gene on one of the DNA strands which codes for specific protein serves as a template onto which mRNA is formed. Enzyme polymeras controls the transfer of code from DNA to mRNA

Question 3

Part 3

Answer 3

Free floating RNA nucleotide in the nucleoplasm form a complementary mRNA strand onto 1 of the DNA template

Question 4

Part 4

Answer 4

A single mRNA strand is formed

Question 5

Part 5

Answer 5

3 nitrogenous bases are known as codon which codes for specific amino acid

Question 6

Part 6

Answer 6

Sequence of the nitrogenous base codon of mRNA forms a complementary of the base triplet of DNA

Question 7

Part 7

Answer 7

Dna base triplet CCA
Rna codon is GGU
Guanine binds with Cytosine
Adenine binds with Uracil

Question 8

Part 8

Answer 8

As the RNA forms. it moves away from DNA the two strand join and twists together again to form double helix structure

Question 9

Part 9

Answer 9

The mRNA strand leaves the nuclear through the nuclear pore into the cytoplasm

Question 10

Part 10

Answer 10

Code obtained by mRNA is taken to rRNA in cytoplasm
