Mcq On Regualtion Of Gene Expression In Eukaryotes

The process of gene expression converts the information stored in DNA into a functional product - protein. This is achieved through the processes of transcription and translation, whereby the DNA code is converted into a protein.

1. Eukaryotic Entities

In the presence of a cAMP molecule, it catalyzes protein synthesis.

(b) Have only operons assisting in gene expression

Transcription takes place in the nucleus and translation in the cytoplasm.

(d) Transcription occurs in the cytoplasm and translation occurs in the nucleus.

Which of the following is not a programming language?

A) Python

B) Java

C) Fortnite

Answer: (C) Fortnite

A genomic DNA contains functional units, which are groups of genes regulated by promoters,

Genes

(b) Operons

(C) Anticodon

(d) Codon

Which of the following is an example of a programming language?

Answer: (b) Java

All regulatory proteins have a shared DNA binding motif that is distinctively flexible in their protein sequences, allowing them to interlock with one another.

The Outside Groove of DNA Helix

(b) The Major Groove of DNA Helix

(c) The Minor Groove of DNA Helix

(d) The Inner Groove of DNA Helix

What is the answer to (a) or (b)?

Answer: (b)

Regulatory proteins can quickly bind to the promoter region at the front of the gene, sometimes even overlapping the promoter, in order to turn off transcription. This site is known as the

(a) Regulatory Site

(b) Operator Site

(c) Suppressor Site

(d) Transcriptional Control Site

Which of the following is a type of computer memory?

Answer: (b) RAM

Seemingly, a protein found in vertebrate cells binds to clusters of 5-methylcytosine, which keeps the regulated gene in the “off” position. This protein’s role in gene regulation is the result of this action.

Methylation

(b) Translación

(c) Enhancer Expression

(d) Operator Suppression

Answer: (a) This sentence is bold

6. Eukaryotic gene transcription is regulated by transcription factors.

Metabolites that bind to the cis-acting elements

(b) Cis-acting elements failing to bind to trans-acting factors

(c) Cis-acting elements binding to trans-acting factors

(d) Repressor proteins that bind to operator sites

Which of the following is true?

  • a) 1 + 1 = 3
  • b) 1 + 1 = 4
  • c) 1 + 1 = 2

Answer: (c)

The ability of some proteins to bind to specific sequences is a basic tool of genetic regulation.

Regulatory DNA Sequences

(b) Regulatory RNA Sequences

(c) Enzymes of Cells

(d) Promoter Portions of Genes
