Organisms contain thousands of different proteins composed of how many different amino acids?
Organisms contain proteins composed of 20 different amino acids. These amino acids can combine in various sequences to form the thousands of proteins found in living organisms.
How is biochemistry used to determine evolutionary relationship?
Biochemistry is used to determine evolutionary relationships by comparing the sequences of biomolecules like DNA, RNA, and proteins from different species. By analyzing the similarities and differences in these sequences, scientists can infer how closely related different organisms are and construct evolutionary trees to show the relationships between them. This helps in understanding the common ancestry and divergence of species over time.
How do organic polymers contribute to biological diversity?
Organic polymers such as proteins, nucleic acids, and carbohydrates are essential building blocks in all living organisms. The unique sequences and structures of these polymers give rise to the diversity of biological functions and properties observed in different species. For example, variations in amino acid sequences of proteins contribute to the diversity of enzymes and structural proteins that drive biological processes. Similarly, differences in nucleic acid sequences lead to genetic diversity and enable the adaptation of organisms to different environments.
Why would different organisms have many different proteins from one another?
DNA codes for RNA which codes for tRNA anticodons that are attached to the amino acid which will make up the polypeptide chain and ultimately the protein. Basically, DNA is the blueprint that will ultimately decide which proteins will be made. Proteins are made up of sequences of amino acids. If two organisms have similar amino acid sequences, that means that they must have similar DNA that told the cells to make those amino acid sequences.
What are the sequences in Dna that determine the Genetic Program?
The sequences in DNA that determine the genetic program are genes. Genes are specific sequences of DNA that encode instructions for making proteins, which are the building blocks of cells and perform various functions in the body. Through the process of gene expression, these instructions are used to carry out the genetic program, influencing traits and functions in an organism.
How do you think the variation in amino acid sequences would impact the functionality and characteristics of different organisms?
The variation in amino acid sequences can impact the functionality and characteristics of different organisms by affecting the structure and function of proteins. Changes in amino acid sequences can alter the shape and activity of proteins, leading to differences in biological processes and traits among organisms.
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 is a genetic trait determined by the genetic code within a DNA molecule?
A genetic trait is determined by specific sequences of nucleotides in the DNA molecule. These sequences are transcribed into RNA, which is then translated into proteins. The proteins produced influence the expression of traits in an organism.
The DNA sequences that make up the genetic code of an organism determine which traits the organism will exhibit.?
Instructions coded by DNA sequences are translated into proteins which express an organism's physical traits

Why do scientists study proteins to find evidence for evolution?
Scientists study proteins to find evidence for evolution because proteins are essential molecules that carry out many functions in living organisms. By comparing the sequences of proteins across different species, scientists can uncover similarities and differences that provide clues about how different species are related and have evolved over time. This can help shed light on the evolutionary history and relationships between species.
What are the differences between amino acid sequence and nucleotide sequence in terms of their composition and function?
Amino acid sequences are made up of building blocks called amino acids, while nucleotide sequences are made up of building blocks called nucleotides. Amino acid sequences determine the structure and function of proteins, while nucleotide sequences determine the genetic information in DNA and RNA.
What do the ribosomes create?
rRNA and associated proteins creates ribosomes.
What bears genetic code?
Genetic code is carried by DNA (deoxyribonucleic acid), which is composed of sequences of nucleotides. These sequences determine the traits and characteristics of living organisms by encoding instructions for protein synthesis. In addition to DNA, RNA (ribonucleic acid) also plays a crucial role in translating the genetic code into functional proteins. Collectively, these molecules form the basis of heredity and biological diversity.
The genetic code directs the synthesis of hundreds of different kinds of?
proteins in living organisms by translating the information stored in DNA into specific sequences of amino acids. This process is essential for cell function and the overall functioning of an organism.
