from different organisms

39. is Biofechnolony safe? Explain and elve 3 examples:

Answer 1

Question	Answer	Justification
1	J	Gene is part of DNA which contain information to form RNA and subequnetly protein
2	D	Transcription is process of formation of RNA from DNA
3	E	Sugar phosphate chain makes the backbone of DNA
4	F	Introns are removed as a part of Alternative splicing and doesn't form mRNA
5	I	DNA replication is semi-conservative as newly generated strand have half new and half old content
6	H	tRNA carries the amino acid and release to binding site during translation process
7	G	DNA ligase joins the Okazaki fragments
8	B	rRNA binds with two ribosomal protein units (small and big) and form ribosomes
9	A	Guanine is complementary to Cytosine while Adenosine is complementary to Thymine
10	C	Anticodon region in tRNA binds to codon region via hydrogen binding
