What is bioinformatics?

field of study that combines biology, computer science, and statistics to analyze and interpret biological data.

Tools used in bioinformatics

include DNA subway, which is a software for genome annotation and visualization, and bit scores and muscle sequence similarity, which are used to compare DNA and protein sequences.

What is the DNA Subway?

a web-based platform that allows users to analyze DNA sequences using a variety of bioinformatics tools.

What does DNA Subway provide access to?

several workflows, such as gene prediction, sequence alignment, and phylogenetic analysis, which can be customized for specific research questions.

Who is DNA Subway designed for?

designed for use by students and researchers with little or no experience in bioinformatics.

What are BIT Scores?

a measure of the similarity between two sequences in a sequence alignment.

How are bit scores calculated?

on the alignment score, which reflects the number and quality of matches and mismatches between the sequences.

What does a high bit score mean?

indicate a higher degree of similarity between the sequences.

What is MUSCLE?

a program used for multiple sequence alignment of protein sequences.

How does MUSCLE align sequences?

Muscle uses an iterative algorithm to align sequences, which takes into account the degree of similarity between

What does COI stand for?

cytochrome c oxidase subunit I, which is a mitochondrial gene commonly used in DNA barcoding to identify and classify species

Why is COI a useful tool in biodiversity research?

The COI gene has a high mutation rate and is conserved across many different species, making it a useful tool in biodiversity research such as Ant DNA Barcoding

What is the purpose of inaturalist?

to help users identify and document plants and animals in the natural world, which can aid in scientific research and conservation efforts.

What do you need when creating an academic poster for science?

clear and concise language, visual aids such as graphs and images, and a logical layout.

What does the academic poster need to include?

a title, introduction, methods, results, and conclusion sections to effectively communicate the research findings.

What is the cell wall of fungi made of?

chitin, a tough polysaccharide that provides structural support to the fungal cell

What organelles does fungi possess?

including mitochondria for energy production, ribosomes for protein synthesis, and a unique organelle called the "spitzenkörper" that is involved in hyphal growth and secretion.

What is the symbolic association between fungi and plant root?

Mycorrhiza is a symbiotic association between fungi and plant roots, where the fungi help the plants absorb nutrients and water from the soil.

What are two main types of mycorrhiza?

endomycorrhiza, where the fungal hyphae penetrate the plant root cells,

and ectomycorrhiza, where the fungal hyphae surround but do not penetrate the plant root cells.

What crucial role does fungi play in the ecosystem?

decomposers, breaking down dead organic matter and recycling nutrients back into the soil.

What can fungi evolve into?

highly specialized decomposers, such as the white-rot fungi that can break down lignin, a tough polymer found in wood.

What is a yeast?

a type of fungus that can survive in both aerobic and anaerobic conditions, making it a facultative anaerobe.

What can yeast do in the absence of yeast?

yeast can undergo fermentation to produce energy and alcohol as byproducts.

What is thallus?

a type of plant body found in algae and fungi that lacks true roots, stems, and leaves.

What is thallus reproduction generation?

The phase of the fungal life cycle where the spores produced by the thallus undergo sexual or asexual reproduction to produce new individuals.

What is Marchantia?

a genus of liverworts that have a distinctive umbrella-shaped archegonium, which is the female reproductive structure that contains the egg

What is the archegonium surrounded by?

a protective layer of cells called the perichaetium.

What is meiosis?

a type of cell division that produces haploid gametes with half the number of chromosomes as the parent cell,

What is mitosis?

a type of cell division that produces two genetically identical diploid daughter cells.

How many rounds of cell division does Meiosis have?

involves two rounds of cell division,

How many rounds of cell division does Mitosis have?

only involves one

What is meiosis used for?

essential for sexual reproduction,

What is mitosis used for?

is responsible for growth, repair, and asexual reproduction.

What is fetal pig dissection?

a common laboratory activity in biology courses that involves the examination of a fetal pig's anatomy.

What is the Ureters in pig?

are the tubes that connect the pig's kidneys to the bladder,

What is the larynx in pig?

is a structure located in the pig's throat that plays a role in breathing and vocalization.

What is the pericardium in pig?

a sac that surrounds the pig's heart and helps to protect and lubricate it.

What is The name for pig ears?

"pinnae."

What are tools used in a pig dissection

scalpels, scissors, forceps, and a probe

What is a neuron?

is a specialized cell that transmits electrical and chemical signals in the nervous system.

What is a synapse?

the junction between two neurons or between a neuron and a muscle or gland cell, where neurotransmitters are released to transmit signals.

What does the central nervous system (CNS) consist of?

consists of the brain and spinal cord,

What does the peripheral nervous system (PNS) consist of?

consists of the nerves that connect the CNS to the rest of the body.

What is action potential?

a brief electrical charge that travels down a neuron's axon, allowing for the transmission of signals.

What is the threshold excitement

the level of depolarization needed to trigger an action potential in a neuron.

What is the refractory period is ?

the brief period of time after an action potential when a neuron cannot fire another action potential.

What is a neurotransmitter?

a chemical messenger that transmits signals between neurons and other cells.

What do Common neurotransmitters include?

dopamine, serotonin, and acetylcholine

What kind of effects can neurotransmitters have on the neurons they bind to?

Neurotransmitters can have excitatory or inhibitory effects on the neurons they bind to, influencing the likelihood of an action potential being fired.
