The following statements are correct EXCEPT: A) Information in the DNA is transcribed int mRNA and translated into proteins B) Information in the DNA is translated int mRNA and transcribed into proteins C) Information in the DNA is copied by DNA polymerase D) The lagging strand during DNA replication is synthesized continuously to form the okazaki fragments E) B and D
In apoptosis, a process of programmed cell death, the cell undergoes controlled degradation of cellular components including nuclear DNA Researchers have noted that if the DNA is isolated from an apoptotic cell, it appears as distinct bands of multiples of approximately 145 bases in length. Why does this occur? Multiple Choice There is a specific DNase that digests DNA every 145 base pairs. DNA sequences that appear every 145 base pairs allows for easier DNA breakage. DNA that is wrapped around the histones is not being degraded. DNA is coated with transcription factors every 145 base pairs.
During replication of a DNA molecule, the daughter strands are not produced in exactly the same manner. One strand, the leading strand, is made continuously toward the replication fork, while the lagging strand is made in fragments in the opposite direction. This difference in synthesis of the two strands is the result of which of the following? O a. DNA polymerase is not efficient enough to make two "good" strands of DNA O b. The two template strands are antiparallel, and DNA polymerase can only synthesize DNA in the 5' to 3' direction O c. The lagging strand is the result of DNA breaks caused by exposure to UV light Od. The cell does not contain enough nucleotides to make two complete strands Oe. Both B&D
Use the picture to solve for the following.
What is the function of DNA primase in DNA replication? to insert new bases during elongation, using the parent strand as a template to anneal (splice) smaller fragments of DNA to create one continuous strand to create an RNA primer to initiate DNA replication to create replication bubbles by unravelling the parental strands of DNA all of the above
Arrange the steps of DNA replication in the order that they occur. First step Helicase unwinds the DNA double helix. Last step Answer Bank DNA polymerase synthesizes DNA. RNA primers are added. DNA ligase joins DNA fragments together. RNA primers are removed. Single-stranded DNA-binding proteins bind to each template strand.
DNA polymerases are processive, which means that they remain tightly associated with the template strand while moving rapidly and adding nucleotides to the growing daughter stand. Which piece of the replication machinery accounts for this characteristic? Helicase Sliding Clamp Single Stranded Binding Protein Primase
Which of the following is matched correctly? DNA helicase: unwinds DNA prior to transcription DNA polymerase: adds RNA nucleotides during transcription DNA polymerase: adds DNA nucleotides during replication RNA polymerase: adds RNA nucleotides during translation All of the above are correctly matched
DNA polymerase 1 has 5' - 3' polymerase activity. 5'-3' exonuclease activity and 3'-5' exonuclease activity necessary for DNA replication. Mutations in the gene that encodes DNA polymerase 1 may cause the enzyme to lose its function. Match the consequence of the lost function mutation to the corresponding lost activity.
Identify whether each of the following descriptions applies to typical prokaryotic genomes only, typical eukaryotic genomes only, both, or neither, according to lecture. Answer options may be used more than once or not at all. Composed of double-stranded DNA only. Each chromosome has a centromere. Species with larger genomes have more genes. [Choose ] [Choose ] prokaryotes only neither eukaryotes or prokaryotes eukaryotes only both prokaryotes and eukaryotes [Choose ]
As the strands are synthesized in replication, which of the following is true? the leading strand is synthesized continuously from the 5' to 3' direction while the other strand is synthesized discontinuously in the 3' to 5' direction both strands are synthesized in the 5' to 3' direction the strand that shows the Okazaki fragments is synthesized in the 3'-5' direction. both strands are synthesized continuously
Below is the 5’–3’ strand of a double-stranded DNA molecule with the following nucleotidesequences (all belong to an exon):5’ C C T A T G C A G T G G C C A T A T T C C A A A G C A T A G C 3’ 1. If the above DNA strand is the template (antisense) strand and the DNA molecule is transcribed that produced a functional mRNA. Assuming there are no mutations, the said mRNA is then brought to the site of protein synthesis,a. what would be the amino acid sequence of the synthesized polypeptide chain?b. how many possible kinds of tRNA molecule that will bring the 2nd amino acid observing wobble hypothesis? List down their anticodons.
