Which of the next pairs is mismatched? RNA polymerase – makes a molecule of RNA from an RNA template DNA ligase – joins segments of DNA DNA gyrase – relaxes supercoiling in DNA forward of the replication fork transposase – cuts DNA spine, leaving “sticky ends” DNA polymerase – makes a molecule of DNA from a DNA template
RNA polymerase – makes a molecule of RNA from an RNA template Clarification: RNA polymerase is an enzyme that catalyzes the copying of a DNA sequence into an RNA sequence throughout transcription. RNA polymerase makes use of a DNA template for the synthesis of an RNA strand. RNA polymerase can be referred to as DNA-dependent RNA polymerase. Throughout transcription, DNA helicase unwinds the double helix of the DNA whereas the RNA polymerase catalyzes the synthesis of an RNA strand from the DNA.
1. The reply is; C When mRNA joins with the subunits of the ribosome, tRNA begins to herald amino acids equivalent to the linear sequence of codons on the mRNA. The tRNA enters the ribosome within the A website of the ribosome, the amino acid detaches and types a polypeptide hyperlink with the opposite amino acid within the P website and the tRNA dislocates, empty, from the E website.
The reply is; C
Throughout replication of DNA, DNA will not be minimize into items. DNA helicases unwind and unzip the DNA double strand and the DNA polymerase begins to copy every stand. This happens by including complementary base pairs to the main and lagging strands.
The reply is; C
In Eukaryotes the place the nucleus is compartmentalized by a nuclear membrane from the cytoplasm, the mRNA strikes from the nucleus via the nuclear pores and goes to the cytoplasm. Within the cytoplasms are ribosomes which might be factories for translation of proteins. The mRNA binds with the ribosome subunits and translation begins into proteins.
The reply is; B
Base pairing rule ensures that the integrity of genes is maintained throughout replication and transcription. Cytosine can solely pairs with Guanine, whereas Adenine solely pairs with the Thyinumes or Uracil (in RNA). This reduces the error price of mismatch pairing.
The reply are as follows;
1)mRNA – a) carries the instruction for protein synthesis from the nucleus to the ribosome 2)tRNA – b) transports amino acids to the ribosome to construct the protein 3)rRNA – c) concerned within the functioning of the ribosome sub-units
b half is true Clarification: plss make me brainliest
C. The few errors made by DNA polymerase are normally corrected by restore enzymes. Clarification: DNA replication is a vital course of, because the daughter cells will want the identical DNA because the guardian. DNA replication makes this occur. Throughout DNA replication, some errors might happen. Whereas these errors are few and much between, they nonetheless do occur. If a number of errors happen, this might outcome within the harm of DNA. Restore enzymes, reminiscent of DNA ligase, assist restore the errors within the DNA so all the pieces goes easily. Restore enzymes repair the DNA so no genetic info is misplaced.
copies of dna Clarification:
DNA polymerase makes a molecule of RNA from a DNA template Clarification: DNA polymerase is an enzyme concerned within the technique of DNA replication. DNA replication replicates or synthesizes a brand new DNA replicate from the parental DNA. The enzymes talked about within the query carry out a specified operate which is matched with their description aside from DNA polymerase as this enzyme is chargeable for including nucleotides to the synthesizing strand from the template strand f DNA. Thus, the chosen possibility is right.
DNA polymerase strikes alongside the previous strand within the 3′-5′ path, creating a brand new strand having the identical 5′-3′ path.
The solutions can be:
c) DNA is minimize into items…
c) it enters the cytoplasm in direction of the ribosome
b) it’s put collectively utilizing base pairing guidelines
rRNA – concerned within the fuctioning of the ribosome sub-units. tRNA – transports amino acids to the ribosome to construct the protein. mRNA – Carries instruction for protein synthesis from the nucleus to the ribosome If you would like to know extra concerning the query, learn on: Translation is the tip level of the protein sythesis course of. That is the place switch RNA (tRNA) carry within the amino acids that pair up with the messenger RNA (mRNA) code created from the DNA of the nucleus. This happens within the ribosome. DNA is minimize into items within the technique of DNA cloning not replication. Throughout replication, DNA first unwinds and unzips with the assistance of an enzyme referred to as helicase. This creates a fork in between the double stranded DNA, exposing every strand. Every of those strands function the template for the brand new molecule, particular to the code. The DNA polymerase helps by including complementary bases to create the mRNA, which is the transcription course of. The mRNA is patterned based mostly on the DNA template it was created from. It’s put collectively utilizing base pairing guidelines. There are solely 4 bases and this contains guanine, cytosine, adenine and thymine. Equally, mRNA have 4 bases as properly, however as an alternative of thymine, it has uracil. Guanine solely pairs with cytosine and vice versa. Thymine pairs with adenine, and adenine pairs with uracil (on RNA). There are various kinds of RNA. mRNA is called the messenger RNA. Because the title it delivers the code to the ribosomes, which is able to inform the cell what amino acids it must make particular to the DNA template it copied from the nucleus. tRNA is called the switch RNA. Its operate is to herald the amino acids to the ribosome. tRNA comprise 3 particular bases that code for a particular amino acid. It matches up with the mRNA that got here from the nucleus. Earlier than tRNA are available, mRNA interacts first with rRNA or ribosomal RNA. This particular RNA is discovered within the ribosome. When mRNA enters the ribosome and binds with the rRNA, their interplay triggers tRNA to method.
The right reply is C) RNA polymerase makes a molecule of RNA from an RNA template. Clarification: RNA polymerase works when the transcription is in course of. Transcription is the making of an RNA strand from a DNA strand that was separated however will come right into a helicoidal form once more. Subsequently, the RNA polymerase makes a molecule of RNA from a DNA template. Additionally, the template has Thymine as an alternative of Uracil (solely present in RNA) so it is DNA.
The right reply might be option-RNA is created from DNA utilizing base-pairing guidelines. Clarification: The method of synthesis of RNA from one strand of DNA is called the transcription. Throughout transcription a number of enzymes act which helps within the synthesis of RNA one among which is RNA polymerase. The RNA polymerase catalyze the addition of a nucleotide to the rising RNA strand utilizing base-pairing rule. The bottom-pairing rule means that A will bind U as an alternative of thymine in RNA and G will bind C within the complementary strand. Thus, option-RNA is created from DNA utilizing base-pairing guidelines is the right reply.
