What is the mechanism by which binding of testosterone to the testosterone receptor leads to upregulated gene transcription
Answer:
This binding causes a conformational change in the receptor which enters into the nucleus and binds DNA to activate transcription
Explanation:
Testosterone is a steroid hormone responsible for inducing protein synthesis and growth of tissues with androgen receptors. Testosterone receptors, also known as androgen receptors, are a class of nuclear receptors activated by binding androgenic hormones (e.g. testosterone) in the cytoplasm, whose binding induces a conformational change of the receptors that are subsequently translocated to the nucleus. Within the cell nucleus, these activated receptors form homodimers that bind DNA in order to promote the transcription of target genes capable of regulating cell growth, cell cycle progression and survival.

Answer: The conversation process where nitrogen gas combines with hydrogen to form ammonium ions is known as THE ACTION OF THUNDERSTORMS while when air in the top layer of soil comes into contact with certain bacteria, nitrogen in the air is converted by NITROGEN- FIXING MICROORGANISMS.
Explanation:
About 79% of air is composed of gaseous nitrogen. However, only a few microorganism can make use of this nitrogen. The important sources of nitrogen for plants and most living organisms are the inorganic nitrogenous compounds in soil. In nature, nitrogen is constantly being removed from the soil and returned to it through the NITROGEN CYCLE
Conversation of gaseous Nitrogen into nitrogenous substances such as ammonium and amino-compouds are carried out by:
--> The action of thunderstorms, and
--> NITROGEN- fixing microorganisms.
During thunderstorms, Nitrogen reacts with oxygen to form nitric oxide. The nitric oxide is oxidizes to Nitrogen peroxide which dissolves in rainwater to form nitric and nitrous acid. When these acids enter the soil, they combine with mineral salts to form nitrates. The nitrates then, dissolve in soil water and are absorbed by the plants. These nitrates are converted into plant proteins and become part of the plant body.
Some microorganisms such as the Nitrogen fixing microorganisms are able to absorb nitrogen from the atmosphere and change it into amino-compouds and proteins. Examples of such microorganisms include:
--> the free living bacteria: these include the azotobacter and clostridium
--> the symbiotic bacteria: the rhizobium which is found in the root nodules of leguminous plants

Explanation:
Only a very few flowering plants have been able to invade the oceans. But the few marine ones are very successful. What are some reasons for the small number of marine flowering plants
Answer:
1. High osmotic pressure due to the hypersaline nature of marine habitats
2. The dependence of flowering plants on pollinating insects for fertilization. These insect pollinators are however, absent in the marine environment.
3. Competition from already-established sea weeds and grasses provides another challenge to flowering plants invadingnthe oceans.
4. Constant changes in the environment as well as temperature changes too
Explanation:
The marine environment is a hypersaline environment with a high salt concentration relative to that of the plant cell. Due to high salt concentration of the marine environment, their is high osmotic pressure on living oragnisms found therein. Organisms must have well-adapted osmo-regulatory mechanisms to counteract the high osmotic pressure of their environment. Therefore, flowering plants face the challenge of removing excess salt from their cells or else lose water to their environment, hence resulting in the death of the plant. However, most flowering plants lack this ability and thus, have found it difficult to invade the oceans.
Flowering plants depends on insect-pollinators for fertilization. However, these insect are not found in the oceans, and as such, it is difficult for flowering plants to invade the oceans.
Well-adapted seaweeds and grasses serve as competitors for any invading flowering plant. Since the flowering plants are not yet adapted for life in marine habitats, they lose out in this competition.
The oceans are constantly in a state of frequent turbulence and change due to tides and currents. Also, the temperature of the oceans are very low and fluctuations in the temperatures of the ocean do occur, utimately serving as obstacles to invading flowering plants to adapt to life in the oceans and seas.

Scientists have discovered a new marine bacterial species called Vibrio nuigii. They have isolated ten strains of this bacterium and determined their whole genome sequences. Only one of the strains (which the scientists named Vir1) is virulent and causes disease in oysters. Describe three ways in which the scientists could use their knowledge of the bacterial genome sequences to identify the genes responsible for virulence.
Answer:
1-by transfecting small interfering RNAs against target genes of interest
2-by using comparative genomics strategies in order to infer functional relationships among target genes of interest and homologous genes responsible for virulence in other bacteria (e.g., antibiotic resistance genes)
3- by inducing mutations through site-directed mutagenesis in order to study gene function (i.e., by examining the effects of knockout mutations)
Explanation:
Whole-genome sequencing (WGS), also known as complete genome sequencing, refers to Next Generation Sequencing technologies that allow the obtention of the entire genetic sequence of an organism/cell, which can be used as a reference genome to understand gene function, evolutionary relationships, etc. The information provided by WGS technologies allows making many different types of genetic analyses in order to understand gene function. First, the nucleotide reference sequence can be used to design complementary small interfering RNAs that trigger degradation of target messenger RNAs (mRNAs) by the RNA interference (RNAi) pathway, thereby inhibiting gene function (in this case, inhibiting genes associated with virulence in the bacterial strain). Second, a reference genome is required to perform bioinformatic data analyses in order to identify homologous genes associated with virulence in evolutionarily related bacteria, allowing identify, for example, antibiotic resistance genes or sequence polymorphisms (e.g., single nucleotide polymorphisms, SNPs) associated with gene function. Third, the information provided by a reference genome can also be used to trigger site-directed mutagenesis (for example, by using the highly precise CRISPR-Cas9 genome editing technology) in order to knock out specific genes of interest and thus analyze if the bacterial strain is still infectious.

Various strains of bacteria are able to transfer genes to eukaryotic hosts. This process of horizontal gene transfer often results in the formation of enzymes in the host organism that assist in metabolic pathways. What is the most likely explanation for why bacterial genes are able to successfully transfer genes that produce enzymes in eukaryotic cells?
Answer:
Due to conjugation.
Explanation:
Bacterial genes are able to successfully transfer genes that produce enzymes in eukaryotic cells because of conjugation process. Conjugation is a process by which one bacterium transfers its genetic material or genes to another bacterium or cell through direct contact with it. During conjugation, the bacterial cells serves as the donor of the genetic material, and the eukaryotic cell serves as the recipient that receives the genes.
