Answer 1

7) B- one new and one old strand in each helix

• The new strands formed  over the templates of old strands will have complementary nucleotide bases. Thus two daughter DNA molecules those formed will have one new strand and one old strand. So other options are wrong,

8) A) chromosome

• It is a unit of inheritance present on the locus of the chromosome and determines the expression of the trait.gene is not found in transfer RNA, enzyme, protein. Inside the nucleus - gene is located in chromosome, so it is the most appropriate answer.

9) A) carry aminoacids to ribosomes-

• tRNA carry specific aminoacids to ribosomes for synthesis of polypeptides. ribosomes is the site of protein synthesis.mRNA carries coded information for protein synthesis.. mRNA itself transfers nucleotides to the nucleus. Promoter in the transcription regulates On and Off of the DNA,

10) C) messenger RNA

• mRNA has a methylated region at the 5' terminal called cap, which help in attachment with ribosome, thus carring genetic information to the nucleus. thus all other options are wrong
• All other RNAs funcions are described in the above question.
