[00:00:00]Hello students, welcome back to PQ series lecture. Previous year questions principle of inheritance 22 questions.

[00:00:19]questions because we have time to mq DNA fragments are need 2027 questionna fragments.

[00:01:01]phosphodosphle basic question.

[00:01:19]Next question. If 999 bases scored for free 333 amino acids and one base deletion occurs, number of altered question A99 Basodons or amino acid effect rightific information 22 33.

[00:02:18]The exact answer all downream All down. Tricky question. Next question. Which enzymes join fragments?

[00:02:43]Simple fragment five prime to three prime DNA replication lagging stands or enzyme DNA liase. DNA lies is the enzyme that binds the parental strand with the new strand fragment.

[00:03:24]Next question.

[00:03:26]Direction of DNA synthesis.

[00:03:38]DNA prime to five to three questionnais or small subunit move to prime option five to three prime and yes we got this answer right simple question next question and experiment DNA replication is experimentervol ecoli solutions semicervative method.

[00:05:13]parental daughter DNA simple question straightforward line then genetic code is the nucleotide sequence from five prime to three prime on mRNAs overlapping.

[00:05:50]So there will be no overlapping ambiguous genetic nonbigetus that's why it is non ambiguous genetic code in genetic code the nucleotides are read in continuous manner degenerate right amino acid non ambiguous amino acid and this multiple coding with different is called as degeneracy or degeneracy of genetic code one of the important features question to question amino acids amino acids amino acid RNA amino Simple questionna.

[00:07:52]This is the central dogma of protein synthesis. Simple straightforward answer to RNA to protein.

[00:08:06]class.

[00:08:09]Next operon is an example of lactose. Operon is the operational unit.

[00:08:36]with multiple genes is called lac operon. Lac operon regulator inhibitors.

[00:09:19]That is a negative regulation.

[00:09:30]TSHNARN after splicing exxons are expressed exons obviously are not used in genetic code option are coding sequence coding sequence exons And they are non-coding sequences.

[00:10:12]are non-coding sequences simple questionna slicing involves it removal of exons.

[00:10:36]Yes, this is the answer. Remove inheritance which acts as a startle question.

[00:11:10]A codein that's why is the initiation.

[00:11:29]Now charge rule states that charge scientist urine pyramid A pairs with P and G pairs with C. This is the complimenting A. So this is the answer B. A pair with C financid in 2,000 base pairs 200 base pairs base pair.

[00:12:33]A T G Cotal base.

[00:12:53]Transcription occurs.

[00:13:07]nucleus and then that is the answer.

[00:13:09]Nucleus is the answer. So transcription nucleus translation cytoplasm transcription nucleus translation cytoplasm.

[00:13:24]Next question. Translation occurs in cytoplasm rights.

[00:13:52]Right.

[00:14:09]UA RNA polymer synthesize RNA polymerase RNA.

[00:14:22]Answer is RNA.

[00:14:36]RNA polymercess question.

[00:15:06]Which chromosome has maximum number of genes in human?

[00:15:22]Chromosome number chromosome number of genetic code means degeneracy amino acid.

[00:15:58]codon or amino acids. Multiple codons will code for one amino acid. So one codon multiple amino acid multiple codons code the same amino acid and this is the answer right. Random coding 64 multiple will be there.

[00:16:36]Operon concept was given by specific operational unit and that is called as operon amino acid specific.

[00:17:05]DNA replication requires DNA concept.

[00:17:18]Yes, we know there is RNA primer. RNA primer.

[00:17:46]So RNA primer is necessary for initiation of DNA replication.

[00:17:59]Majority of questions specific topics% questionsetics evolution topic All the best.
