Consider the separate stages of an animal virus life cycle. Assemble a list of structures and processes that are unique to the virus and would make good drug targets for an antiviral agent. Explain your rationale for each choice.
Answer:
Explanation:
In order to make an antiviral agent, we need to find good drug targets, that is, to find structures and processes that are only present in the virus, so there is no harm on human cells when this antiviral agent is being applied.
In the virion of a naked virus, only nucleic acid and protein are present forming the nucleocapsid. The nucleic acid and proteins of the capsid, specially, are found only in the virus and therefore make good drug targets. For example, we can express antibodies to recognize the proteins of the capsid and guide the immune system to destroy them.
Although virus particles are metabolically inert, one or more key enzymes are present within the virion in some viruses, for example, the reverse transcriptase. This enzyme is only found in viruses and if we find a way to inhibit the activity of this reverse transcriptase, like for example finding a competitor substrate, the virus will not be able to synthesize the DNA needed for its replication.
Regarding processes in the virus life cycle, they all have similar steps: first the attachment of the viral particle onto the cell, then the penetration of the virus, then the synthesis of early and intermediate enzymes using the host cell machinery, and finally the assembly of these viral components and lysis of the host cell to release new viral particles.
The attachment of a virion to a host cell is a highly specific process. Recognition proteins on the virus recognize specific receptors on the host cell. Substances that compete with the virion for these specific receptors can be used. If there is no attachment, there is no infection.

The descriptive term for plants that are sturcturally adapted to withstand protracted dry conditions is ___________.
Answer:
Xerophytic
Explanation:
It is xerophytic and it is gotten from Greek word, Xeros( dry) and phutons(plants). It is an adaptive term that is use to describe plants species that posses structural adaptive features which make them to adapt and survive in areas where there is little water or dry region like desert, or area covered with ices by possessing some mechanism which help them to reduce water loss or concerns water. Examples include cactus, pineapple and some Gymnosperm plants. Some of these plants species posses extensive root system and their leaves are reduced to cacti which does not support water loss.

A mutation has occurred that results in a drastic reduction in mRNA transcription from very high levels to low levels. What region is likely responsible?
Answer:
Enhancer region
Explanation:
An enhancer is a cis-regulatory DNA region that binds to transcription factors in order to stimulate transcription. Enhancer regions are localized both upstream and downstream of the gene whose transcription regulates, at a variable distance ranging from 1 to 100 kilobases (kb) from the transcription start site. The first enhancer to be identified was found in an intron of the immunoglobulin gene. Conversely, a silencer element is a DNA region that binds to proteins known as repressors in order to suppress transcription.

A cell has chloroplasts, numerous ribosomes, an endoplasmic reticulum, and a cell wall. What type of cell is this?
Answer:
The cell with chloroplasts, abundant ribosomes, plus an endoplasmic reticulum, and a cell wall is of the plant cell type.
Explanation:
Plant cells are eukaryotic cells found in all plants, with specific characteristics given their ability to be autotrophic and use solar energy to synthesize their nutrients. The presence of many ribosomes and a developed endoplasmic reticulum is due to their high capacity for plant protein synthesis.
One characteristic that differentiates plant and animal cells is the presence of a cell wall, which surrounds the cell membrane, and chloroplasts. Chloroplasts are responsible for making the process of photosynthesis possible.

How do heredity and inheritance relate to the data presented In these charts
Your risk is greatly raised if any of these relatives have had breast or ovarian cancer. However, until many of these “secondary” relatives have the disease.
What is role of inheritance in breast cancer?A woman's risk of breast cancer nearly doubles if she has a first-degree family (mother, sister, or daughter) who has the disease.
Her risk is nearly three times higher if she has two first-degree relatives. A woman's risk of developing breast cancer is considerably higher if her father or sibling had the disease.
Gene changes that are connected to breast cancer are typically acquired. Only the breast cancer cells experience acquired DNA alterations over time.
Therefore, Hereditary is Breast cancer and Inheritance is Getting Breast Cancer, basically it runs in the family inheriting.

Mutation 1 will cause translation to stop as there is presence of stop codon UAG, UAA, UGA.
What are the stop codons ?
In DNA or messenger RNA (mRNA), a stop codon is a sequence of three nucleotides (a trinucleotide) that tells the cell to stop making proteins. There are 64 distinct codons for trinucleotides. Three stop codons (UAA, UAG, and UGA) and 61 specific amino acids are included.Several codons, or triplet bases, make up the universal genetic code. To reduce coding errors, the standard code has developed over time. The genetic code is made up of 64 codons that are the result of the four bases in nucleic acids being permuted and combined.Since more than one codon can encode for a single amino acid, the genetic code is degenerate. Consequently, 61 of the 64 codons encode the 20 amino acids.The START and STOP codons, two punctuation marks in the genetic code, indicate the conclusion of protein synthesis in all organisms.Because it is the first codon in the transcribed mRNA to undergo translation, the codon AUG is referred to as the START codon. The amino acid methionine (Met) in eukaryotes and formyl methionine (f Met) in prokaryotes are both encoded by the most prevalent START codon, AUG. With the assistance of a few initiation factors, the t RNA recognizes the START codon AUG during protein synthesis and initiates mRNA translation.Amber (UAG), opal or umber (UGA), and ochre (UAA) are the three STOP codons. Charles Steinberg and Richard Epstein discovered Amber" or UAG and gave it the name "amber" after the German meaning of their friend Harris Bernstein's last name. In order to keep with the theme of "color names," the two remaining STOP codons were subsequently given the names "ochre" and "opal."To know more about codons check this:

describe how and where carbondioxide enters the leafe?
Answer:Carbon dioxide cannot pass through the protective waxy layer covering the leaf (cuticle), but it can enter the leaf through an opening (the stoma; plural = stomata; Greek for hole) flanked by two guard cells. Likewise, oxygen produced during photosynthesis can only pass out of the leaf through the opened stomata.

Based on the thin layer of sediment on his flooded farm,
James Hutton concluded that strata:
A Are made of large rocks
B
Settle in vertical layers
C
Are formed by catastrophes like floods and earthquakes
D
Take many thousands of years to form
Answer:
D. Take many thousands of years to form
Explanation:
James Hutton discovered thin layers of sediments on his flooded farm and he concluded that strata was part of the earth surface in the past and thus takes many thousands of years to form.
This led to the principle of uniformitarianism which states that the geologic processes now are the same with the ones in the past.
