Which of the following statements about eukaryotic mRNA processing is not correct?

Biology
1 answer:
ch4aika [34]3 years ago
6 0

Answer:

The correct answer will be option-D.

Explanation:

In eukaryotes, the process of transcription takes place inside the nucleus whereas translation takes place in the cytosol. So, mRNA has to export to the cytosol from the nucleus.

Before export, the post-transcriptional modification takes place like 5' capping, 3' tailing and splicing mechanism.

The capping is done at 5' end by adding modified guanine (G) nucleotide which protects the mRNA from exonuclease activity and tailing is done at 3' end by adding adenine nucleotides which provides stability to the mRNA.Splicing removes the junk DNA called introns and joins the exons before export.

Thus, option-D is the correct answer.

You are doing an experiment and plated E. coliin different medias. Media A has onlyglucose, B has only lactose, and media C has
krek1111 [17]

Answer:

A. Glucose:

As lactose is absent will follow the glucose metabolism, so the lac repressor will hold tightly with the operator which leads to the prevention of transcription as RNA polymerase can not bind to promoter so no lactose metabolism.

B. lactose:

In the case or wild mutant lactose metabolism will occur as lactose is present, allolactose binds to the lac repressor thus the operator and promoter are free so transcription starts.  The same result will be in all test except in the case of a mutant repressor.

C. glucose and lactose:

In this case, diauxic growth will occur. This growth takes place when two sugars are present in the media. The preferred sugar will be consumed first That is glucose. Then a lag phase will come which will be followed by the second sugar metabolism that is lactose.  the given two cases :

Lactose will be metabolized first, as operator site mutation prevents repressor protein binding and thus will lead to the constitutive synthesis of lac operon in test B.   The same thing will happen, as in this case also, constitutive synthesis of lac operon will happen in test C.

Cultures grown in the presence of both glucose and lactose are metabolizing lactose. In the test (b) and (c) will be responsible due to constitutive synthesis of lac operon will happen.

VikaD [51]

Answer:

<em>Translation will be affected.</em>

Explanation:

Ribosomes are the sites where the process of translation errors. Translation can be described as the process by which mRNA is converted into the amino acids which make up specific proteins of the body. If a mutation in the genes that code for proteins of the ribosome occurs, then the process of translation will be affected. Faulty proteins may be formed as a result of this mutation which can be harmful for the body.
