Which DNA strand is the template strand Which of the followi

Which DNA strand is the template strand? Which of the following statements are true/false? The mRNA sequence is similar to the coding sequence. The mRNA sequence is similar to the gene sequence. The mRNA sequence is similar to the template sequence. The mRNA sequence is complementary to the coding sequence. The mRNA sequence is complementary to the gene sequence. The mRNA sequence is complementary to the template sequence. The gene sequence is similar to the coding sequence. The gene sequence is similar to the template sequence. The gene sequence is complementary to the coding sequence. The gene sequence is complementary to the template sequence.

Solution

1) DNA has two starnds. Template strand and coding strand. Template strand of DNA transcribes the mRNA. It acts as a template for the production or synthesis of RNA which is later translated into protein. This strand is not involved in coding which is why it is also known as non-coding strand. The template strand has the base sequences opposite to that of the base sequences in mRNA.

2) a) The mRNA sequence is similar to the coding sequence :true

b) The mRNA sequence is similar to the gene sequence : true

c) The mRNA sequence is similar to the template sequence : false

d) The mRNA sequence is complementary to the coding sequence : false

e) The mRNA sequence is complementary to the gene sequence : false

f) The mRNA sequence is complementary to the template sequence : true

g) The gene sequence is similar to the coding sequence : true

h) The gene sequence is similar to the template sequence : false

i) The gene sequence is complementary to the coding sequence : false

j) The gene sequence is complementary to the template sequence : true
