How has the lab technique PCR helped scientists study evolutionary relationships?
PCR helps, specifically, with finding homology between sequences of dna quickly and spefically where scientists want to look in the genomes. PCR, by using 'primers,' pinpoint exactly where they want to make copies of DNA. By making these copies, they can be read by a machine and from there, 'multiple sequence alignment' can be performed to examine evolutionary relationships. These sequences and homology matter to scientists such as structural biologists who want to find out the specific 3D shape of homologous proteins or RNA. They can use homology in, say mice (mammal) DNA sequences to make predictions about the shape of human proteins/RNA--therefore finding ways to attack a 3D structure with a new synthetic medicine.
What else can I help you with?
Can you Compare the updated classification of protists with the older one?
The updated classification of protists uses molecular data to group organisms based on evolutionary relationships, leading to a more accurate and comprehensive classification system. In contrast, the older classification relied heavily on morphological characteristics, resulting in some inaccuracies and uncertainties in the relationships between different protist groups. The new classification system has helped to clarify the diversity and evolutionary history of protists.
How do you get rid of air plants on shrubs?
Burning is a good technique, it helped me get rid of the air plants on my shrub.
What two major developments helped scientists explain the fossil record?
The theory of evolution by natural selection, proposed by Charles Darwin, helped scientists understand the gradual change of species over time recorded in the fossil record. Additionally, advances in radiometric dating techniques provided scientists with the ability to determine the age of fossils more accurately, allowing for a deeper understanding of the timeline of life on Earth.
Robert Hook's discovery helped scientists learn more about?
Robert Hooke's discovery of cells in 1665 helped scientists understand the fundamental unit of life and laid the foundation for the field of biology. His work led to the development of the cell theory, which states that all living organisms are composed of cells.
Muslim scientists made major advances in the field of optics. This helped them to treat which part of the body?
its is the eyes
Which technique helped scientists in the 1800 to identify cell organelles?
The development of the light microscope in the 1800s helped scientists identify cell organelles. This allowed for better visualization of the internal structure of cells and facilitated the discovery and characterization of organelles such as the nucleus, mitochondria, and chloroplasts.
How has the theory of evolution affected the science of taxonomy?
The theory of evolution has influenced taxonomy by providing a framework to understand and classify species based on their evolutionary relationships. Taxonomists now use evolutionary principles to group organisms into categories that reflect their common ancestry, leading to a more systematic and comprehensive classification system. This has helped improve our understanding of biodiversity and the relationships between different species.
Why do scientists classify life?
They classify life so that 1. we can learn more. duh. but the other reason is so that they can discover new things in life and help save lives.:*) I hope i helped with this question
What is the furthest step that has been achieved in study of human origin?
The furthest step achieved in the study of human origins is the discovery of ancient hominid fossils that provide important insights into our evolutionary history. These fossils have offered valuable information about the species that preceded modern humans and helped to uncover our evolutionary relationships with other hominids. Scientists continue to make advancements in this field through the use of genetic research, archaeological evidence, and comparative anatomy studies.
Why did DNA technology lead to more use if cladistics?
DNA technology allowed for the direct comparison of genetic material between organisms, providing a more precise and objective way to establish evolutionary relationships. This data could then be used in cladistics to construct more accurate phylogenetic trees and classification systems. Overall, the use of DNA technology in cladistics helped to improve the accuracy and reliability of evolutionary relationships among organisms.
Which scientists helped to determine the shape of DNA?
The scientists who helped determine the shape of DNA were James Watson and Francis Crick.
Why did DNA technology leadre use of cladistics?
DNA technology revolutionized the study of evolutionary relationships by providing a way to compare genetic sequences directly, allowing for more precise and objective determination of relationships between species. Cladistics, a method of classification based on evolutionary relationships, became popular in the wake of DNA technology because it provided a systematic way to organize the newly available genetic data into branching family trees. This helped researchers understand the relatedness of species and how they evolved over time.

The updated classification of protists uses molecular data to group organisms based on evolutionary relationships, leading to a more accurate and comprehensive classification system. In contrast, the older classification relied heavily on morphological characteristics, resulting in some inaccuracies and uncertainties in the relationships between different protist groups. The new classification system has helped to clarify the diversity and evolutionary history of protists.

How has genetics helped in our understanding of evolution?
Genetics has helped in our understanding of evolution by providing insights into how variations in DNA sequences can lead to differences in traits among organisms. By studying genetic changes over time, scientists can infer how species have evolved and diversified from a common ancestor. Comparing genetic similarities and differences between different species also allows for the reconstruction of evolutionary relationships and the development of phylogenetic trees.
How have microscopes had an effect on classification?
Microscopes have allowed scientists to observe minute details of organisms, leading to the discovery of new characteristics that aid in classification. This has helped in identifying new species, understanding evolutionary relationships, and revising existing classification systems based on morphology and cell structure.
What are 3 ways to determine the phylogenetic relationship among species?
DNA sequencing: By comparing the genetic sequences of different species, their evolutionary relationships can be inferred based on the similarities and differences in their DNA. Morphological characteristics: Examining the physical traits and structures of species can provide clues about their evolutionary history and how closely related they are. Fossil records: Studying the fossilized remains of species can reveal their evolutionary history and help determine their phylogenetic relationships with other species.
