Multiple choice biochem 1 which of the following is true of...

1. Which of the following is true of RNA synthesis? Select one: a. All of these b. A long DNA-RNA hybrid helix is formed for the entire length of the transcribed gene. c. A DNA template strand is required. d. An RNA primer is required. 2. Which of the following is true of prokaryotic transcription? Select one: a. The C-terminus of the RNA polymerase must be phosphorylated for RNA synthesis to begin. b. Prokaryotic transcripts are often polycistronic. c. Co-activators must be recruited to unwind nucleosomes. d. The sigma factor is associated with RNA polymerase during elongation and termination.

Transcript

00:01 Okay, i'm going to answer this question.

00:01 We have to talk about dna.

00:03 Well, transcription.

00:04 If this is your dna, your dna is a double -stranded molecule, and it contains genes.

00:09 For example, suppose here you have a gene or here.

00:14 Okay, this is one gene.

00:15 And this gene, when our cell wants to express this gene, it is going to produce a single -stranded mrna.

00:24 In this process of producing this mrna is called transcription.

00:33 Okay, transcription.

00:34 Then this mra is going to leave the nucleus because all of these occurs in the nucleus and it is going to go to the cytoplasm where it is going to bind the ribosomes.

00:43 The fibrosomes are going to read the information covered by this mna and it is going to produce a protein.

00:49 So this protein is going to have the information in this gene.

00:53 So it is particularly just a long process, but well this is the end result of this.

00:58 Question number one says, which of the following is true of rna synthesis? option a says all of these well this is option a option b says along dna rna hybrid elixis formed for the entire length of the transcribed gene and this is false because your rna is made of only rna it is not like a hybrid of dna and rna okay so this is not the answer and hence also option a is not the answer option c says a dna template is randomly required and this is true because dna has two strands, one strand is a coding strand, and another strand is a temporary strand.

01:39 This template strand is going to be useful to produce that mra name...
