How is rRNA important for making proteins?
Ribosomal ribonucleic acid, also known as rRNA, is important for making proteins because these proteins help to link evolutionary relationships of a species. Each rRNA consists of 40% of protein.
Why do scientists study proteins to find evidence for evolution?
Proteins reflect DNA sequences, so scientists study proteins to look for genetic similarities and differences in organisms.
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.
Which type of molecule would be used to determine relationships in the science of comparative biology?
DNA and proteins
What is the similarity in the structure of a protein and nylon?
Proteins are made from amino acids. Proteins are made up of long chains of amino acids joined together by peptide bonds.Proteins are polymers. Amino acids are their monomers.
State how comparing the amino acid sequence of a protein can provide evidence that evolution has occured?
Proteins are excellent sources for evidence of evolution, because their structure is determined genetically. Genes code for the amino acid sequences of proteins, so variation in protein structure can be directly linked to genetic variation. In fact, in the years prior to the ability to sequence DNA, the amino-acid sequences of proteins were used to infer the DNA sequences of the genes that coded for them. Since evolution is defined as genetic change within populations, proteins and their patterns of variation provide powerful evidence for that.
Do two proteins that have similar amino acid sequences have similar functions even if they are isolated from different organisms?
Functional similarity depends on the similarity percentage and the positioning of the conserved residuesin the sequences that are important for interaction. Usually the sequences showing 35% or more MAY tend to show functional similarity but again as i said it ALSO depends on the conserved residues in the sequences which may be located in the active site.
How did amino acids fall into the evolutionary theory?
Amino acids are not part of evolutionary theory. Evolution is the change in allele frequency over time in a population of organisms. The theory of evolution by natural selection explains much of the mechanism for evolution. Alleles are different molecular forms of the same gene. This means different alleles could code for the manufacturing of different proteins, or proteins with different functions. Proteins are made of amino acids, which is as close as amino acids get to the theory of evolution. If it were some other molecule then the theory of evolution would still be explaining much the same thing.
How are evolutionary relationships important in classification?
Evolutionary relationships are important in classification because they help us understand the relatedness between different organisms. By studying similarities and differences in anatomical structures, genetic sequences, and other characteristics, scientists can group organisms into taxonomic categories based on their common ancestry. This helps in building a more accurate and informative classification system that reflects the natural history and diversity of life on Earth.
Genetic material must be able to?
it must be able to produce complete working proteins, have the ability to adapt to changes, to reolicate faithfully and they must allow for evolutionary change
What has the author Joakim Bjerketorp written?
Joakim Bjerketorp has written: 'Novel adhesive proteins of pathogenic Staphylococci and their interaction with host proteins' -- subject(s): Host-bacteria relationships, Stapholococcus aureus, Virulence (Microbiology), Microbial invasiveness, Bacteriophages
What sources of information do taxonimists use to determine evolutionary relationships between groups of organisms?
Taxonimists use several different pieces of information... previously it was based on similarities in FORM, of body, body parts, skeleton, etc. Now genetic information is used, but there are still various pieces to look at. for example, the types of muscle proteins in fish can be used to estimate relationships. Really, it is a conglomeration of many different pieces, and not all of them agree, because some give protein data more weight, and some give other features more weight.
