Please select the correct statements about the process of transcription. RNA polymerase works by adding nucleotides one by one through complementary base pair matching. The resulting RNA molecule will have exactly the same bases as DNA. RNA polymerase works by adding nucleotides one by one through complementary base pair matching. The resulting RNA molecule will have U (Uracil) in place of T (Thymine). RNA polymerase is the enzyme that transcribes DNA from the template strand. The RNA polymerase tracks along the DNA and helps match bases. The A base in DNA pairs with a U base in RNA, while a T base in DNA pairs with an A base in RNA

Transcript

00:01 Okay, now i want to answer this question, let's talk about dna.

00:03 Question number one says dna polymerase, and we have to choose the correct option.

00:08 It says produces dna from mrna, and this is false because this is what normally happens, okay? from dna to mrna, this process is called transcription, and the enzyme responsible here is rna polymersics.

00:24 And this option a is talking about this, okay? and the enzyme that does this process here is a type of rna polypricis.

00:32 It is called rna -dependent dna polymerase.

00:36 So this is false, because what dna polymeris actually does, it is going to produce dna from dna.

00:43 It means it is going to participate in the process of dna replication.

00:47 Option bises assembles the nucleotin.

00:49 It is true because if this is your parental strand of dna, your dna polymerase is going to build a complementary dna strand.

00:57 If this is going to be your parental strand, and this is going to be the new strand that dna polymerase has produced and this black strand is going to be complementary to the greatest strand.

01:08 It means according to base pairing rules where i think is going to pair with timing and cytosing with 1.

01:14 So let go for option c that says responds to signals that initiate cell division and this is also true.

01:22 So we have option d that says all are correct and this is false because option a is not true.

01:28 And option e says b and c are correct and this is the answer for this question.

01:32 Okay, option e.

01:32 Now let's go for the next question that says, which of the following statements are false about your application.

01:39 This is question number two and let's look at the options.

01:41 Option a says dna polymerase works in a 5 to 3 direction.

01:46 Remember that your dna polymerase, say here, it's going to get the parental strand from 3 to 5 in a 3 to 5 direction, and it is going to polymerize from 5 to 3 direction.

01:59 Okay, so practically option a is true and this is not the answer because we're looking for the false work.

02:02 Option b says the enzyme primates as a dna primer.

02:08 And this is false because if this is your parental dna strand and you want to synthesize, here you're like a daughter strand, you're going to acquire dna polymers.

02:17 But dna, but this dna polymeris cannot start synthesizing the dna strand out of nothing.

02:21 It is going to require a short segment here that is called a primer.

02:26 And this primer is rna...
