What is A spore producing reproductive structure of a fungus called?
Sexual spores are found to be formed in different strains of the same species. Spores are reproductive cells that can develop into new individual.
What is a pure substance which is formed by a chemical reaction between two or more different substances called?
A compound is the pure substance formed from the chemical combination of two or more different elements.
When a new substance is formed with different properties than the original substance it is called a?
physical change
What happens during rna splicing m?
Gene splicing means cutting of gene in fragments and rejoining them according to need There are two phenomenon by which gene splicing occur one is natural i.e. post transcriptional modification and other is artifically or by chemical agent used generally in recombinant technologyPOST TRANSCRIPTIONAL MODIFICATION: Gene splicing is a post-transcriptional modification in which a single gene can code for multiple proteins. Gene Splicing is done in eukaryotes, prior to mRNA translation, by the differential inclusion or exclusion of regions of pre-mRNA. Gene splicing is an important source of protein diversity. During a typical gene splicing event, the pre-mRNA transcribed from one gene can lead to different mature mRNA molecules that generate multiple functional proteins. Thus, gene splicing enables a single gene to increase its coding capacity, allowing the synthesis of protein isoforms that are structurally and functionally distinct. Gene splicing is observed in high proportion of genes. In human cells, about 40-60% of the genes are known to exhibit alternative splicing.Gene Splicing MechanismThere are several types of common gene splicing events. These are the events that can simultaneously occur in the genes after the mRNA is formed from the transcription step of the central dogma of molecular biology.Exon Skipping: This is the most common known gene splicing mechanism in which exon(s) are included or excluded from the final gene transcript leading to extended or shortened mRNA variants. The exons are the coding regions of a gene and are responsible for producing proteins that are utilized in various cell types for a number of functions.Intron Retention: An event in which an intron is retained in the final transcript. In humans 2-5 % of the genes have been reported to retain introns. The gene splicing mechanism retains the non-coding (junk) portions of the gene and leads to a demornity in the protein structure and functionality.Alternative 3' splice site and 5' splice site: Alternative gene splicing includes joining of different 5' and 3' splice site. In this kind of gene splicing, two or more alternative 5' splice site compete for joining to two or more alternate 3' splice site.A gene-sized fragment of DNA is isolated from another organism. The bases of the fragment are spliced (joined) to the bases of the molecule by using a chemical called ligase.
After plants moved to land what happnend?
adaptive radiation formed mant new land plant species
What is the process by which new species is formed called?
That process is called Speciation!
Some species becoming extinct and new species being formed is called?
Evolution
When deoxyribonucleic acids from two different species are joined together the newly formed molecule known as?
When two different species' DNA is joined together, the resulting molecule is called recombinant DNA. This process is often used in genetic engineering to create organisms with desired traits or characteristics.
What is A spore producing reproductive structure of a fungus called?
Sexual spores are found to be formed in different strains of the same species. Spores are reproductive cells that can develop into new individual.
How do fossils that formed in different rock layers provide evidence-of evolution?
Fossils' existence confirms that species are not fixed but can evolve into other species over time
How many ascospores are formed in an ascus?
there are eight ascospores formed in an ascus
How did Darwin say that new species are formed?
That organisms were modified over time by a process called natural selection. The nonrandom survival and reproductive success of randomly varying organisms.
What is it called when leafy roof formed by tall trees?
A leafy roof formed by tall trees is called a canopy. Canopies provide shade, shelter, and habitat for a variety of plant and animal species in forest ecosystems.
What Charles Darwin is known for?
Charles Darwin is known for his studies aboard the HMS Beagle. He went all around the world to study different species and formed the theory of evolution.
Why is Mantyke called Mantyke?
It is a child form of Mantine, formed by the words 'Manta', from the species of manta rays, plus 'tyke', a child.
How did sedimentary rock got the name?
It is called this because it is formed from different kinds of sediment.
If i don't want to mate with an ugly girl does that make me a different species than her Because for a new species to be formed they have to be different enough and not inbreed.?
Not wanting to mate with someone based on physical attractiveness does not make you a different species. Biological species boundaries involve reproductive isolation, meaning individuals cannot produce viable offspring with members of another species. Preference for attractiveness or mate selection is a personal choice and does not influence biological species classification.
