If you were a scientist developing a drug that would block viral replication which steps would you choose to block?
The steps of viral replication are attachment, penetration, uncoating/disassembly, transcription/translation, and assembly/release. Choose the one you believe will be the most effective for blocking the viral replication without harming humans and their DNA replication.
What section of the periodic table includes the s block and p block?
S-BLOCK IS FROM GROUP # 1-2 P-BLOCK IS FROM GORUP # 13-18 S-BLOCK IS FROM GROUP # 1-2 and P-BLOCK IS FROM GORUP # 13-18
What is the block of sulfur?
Sulfur (S) is a p-block element.
Which block contains 5 orbitals?
The D-block
What block are the transition metals found in?
The inner transition metals belong to the f block on the periodic table. Examples of f block elements are cerium, gadolinium, terbium and lutetium.
What is Corepressor and their function?
The metabolite that when bound to the repressor (of a repressible operon) forms a functional unit that can bind to its operator and block transcription.
How is a non-constituative gene turned off?
repressor proteins block the gene physically and prevent transcription from occurring
What is L-tryptophan and how does it affect us?
An amino acid, a protein building block that can be found in many plant and animal proteins. L-tryptophan is called an "essential" amino acid because the body can't make it. It must be acquired from food. L-tryptophan is used for insomnia, sleep apnea, depression, anxiety, facial pain, a severe form of premenstrual syndrome called premenstrual dysphoric disorder (PMDD), smoking cessation, grinding teeth during sleep (bruxism), attention deficit-hyperactivity disorder (ADHD), Tourette's syndrome, and to improve athletic performance.
Why is it important for DNA to condense before dividing?
DNA condensation is used to block the transcription and translation of a number of genes. It is part of "epigenetics" by condensation of the DNA the polymerase can no longer bind.
What are three ways in wich protein bind to enhancer of a gene can work to regulate gene expressions?
1- enhance transcription 2- attract RNA polymerase 3- block acces to genes

What does the addition of methyl groups to DNA cause?
Block RNA polymerase from attaching to DNAorcan directly switch off gene expression by preventing transcription factors from binding to promoters, segments of DNA that promote expression of a particular gene.
How do cells control gene expression?
The promoter allows the gene to be transcribed. It helps RNA polymerase find where a gene starts. An operator is a DNA segment that turns the gene "on" or "off." It interacts with proteins that increase the rate of transcription or block transcription from occurring.
On what organelle in the cell does protein synthesis occur?
Protein synthesis takes place in the ribosomes and also in the Rough Endoplasmic Reticulum (RER).
What are four ways transcription is repressed?
Transcriptional repressors: Proteins that bind to specific DNA sequences near the promoter region of a gene and block the binding of transcription factors and RNA polymerase, preventing transcription initiation. Chromatin remodeling: Repressive chromatin modifications, such as DNA methylation or histone deacetylation, can make the DNA inaccessible to transcription machinery, hindering transcription initiation. Transcriptional interference: Overlapping or nearby transcriptional events can interfere with each other, leading to the repression of one or both transcription processes. RNA-mediated repression: Certain non-coding RNA molecules can bind to mRNA transcripts, inhibiting their translation and subsequently repressing gene expression at the post-transcriptional level.
When was Block to Block created?
Block to Block was created in 1981.
