Is the meaning acid sequence of the two organisms are similar would their DNA be also similar Why?

Yes. If the amino acid sequence of two organisms are similar, then the organisms’ DNA sequences would also be similar. The central dogma of biology states that DNA contains the key for RNA, which then codes for proteins. During transcription, the two strands of DNA unwind.

How are amino acid sequences related to DNA?

genetic code, the sequence of nucleotides in deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) that determines the amino acid sequence of proteins. Though the linear sequence of nucleotides in DNA contains the information for protein sequences, proteins are not made directly from DNA.

How are amino acid sequences used to determine common ancestry?

That two species and their common ancestor have similar DNA is strong evidence supporting evolution. Protein amino acid sequences can also be used to compare similarities between species. Proteins are made from amino acids and the sequence of these amino acids is controlled by genes.

Which type of evidence for evolution compares DNA and or amino acid sequences of organisms to see how closely related they are?

Molecular clocks are used to determine how closely two species are related by calculating the number of differences between the species’ DNA sequences or amino acid sequences. Molecular evidence for evolution includes that all living things share the same biochemical building blocks.

What is the difference between DNA sequence and amino acid sequence?

The key difference between base sequence and amino acid sequence is that base sequence is the nucleotide sequence of a DNA or an RNA molecule, while the amino acid sequence is the string of amino acids linked together in a peptide or a protein. DNA stores genetic information of an organism.

How are amino acid sequences used to figure out if two species are closely related?

Because the DNA sequence determines a protein’s amino acid sequence, a gene shared by two closely related organisms should have similar, or even identical, amino acid sequences. That’s because closely related species most likely diverged from one another fairly recently in the evolutionary span.

How would different amino acid sequences affect organisms?

How do you think different amino acid sequences would effect organisms? … THE SEQUENCE OF AMINO ACIDS IN A PROTEIN DETERMINE ITS FUNCTION. THE MORE SIMILAR THE SEQUENCE BETWEEN TWO ORGANISMS, THE MORE SIMILAR THE FUNCTION OF THEIR PROTEIN, THE MORE SIMILAR THEIR FUNCTION IN EACH ORGANISM.

How are amino acid sequences of two organisms similar?

If the amino acid sequence of two organisms are similar, then the organisms’ DNA sequences would also be similar. The central dogma of biology states that DNA contains the key for RNA, which then codes for proteins. Transcription and translation are the two phases of protein synthesis. During transcription, the two strands of DNA unwind.

What is the similarity between DNA and proteins?

The DNA will be similar because DNA acts as a direct blueprint for the proteins. The sequence of bases in DNA codes, in sets of 3, for specific amino acids. The code is read from the DNA by mRNA (messenger RNA); that is then translated by tRNA into amino acids.

How do you determine the amino acid sequence of a protein?

The amino acid sequences of a protein are determined by the genes that code for the proteins. By determining the amino acid sequence of homologous proteins in different organisms, such as the ribosome proteins, you can determine what the gene sequence is. The more similar a gene sequence is, the more closely related the organisms are.

How do scientists determine how closely related two species are?

In general, scientists say the longer ago two species split, the more distantly related they are. You may need to remind your students about the nature of DNA, genes, proteins, and amino acids and how they differ from one another. DNA is a molecule made up of four types of units called bases.
