Histones are proteins that bind to DNA in the cell nucleus and play a role in regulating gene expression, but they do not contain signal sequences for targeting to specific cellular compartments.

Munich Information Center for Protein Sequences was created in 2010.


What similarities in DNA and protein sequences do humans and chimpanzees share?

Humans and chimpanzees share about 98.7 of their DNA sequences and have similar protein sequences due to their close evolutionary relationship.


Which are more conserved DNA or protein sequence?

Protein sequences are generally more conserved than DNA sequences because of the redundancy in the genetic code. Mutations in DNA can sometimes result in the same amino acid being coded for, so changes in DNA sequences do not always lead to changes in protein sequences. Additionally, certain protein sequences are critical for their function, making them more constrained and therefore less likely to change.


What percentage of the human genome is comprised of protein-coding sequences?

Approximately 1-2 of the human genome is made up of protein-coding sequences.


Which parts of a gene are expressed as protein?

Coding sequences of a gene are expressed as protein


When looking at a table depicting the genetic code the base sequences signify?

When looking at a table depicting the genetic code, the base sequences signify the specific arrangement of nucleotides that code for amino acids. Each three-letter combination, or codon, represents an amino acid or a start/stop signal. These sequences are the instructions for protein synthesis in living organisms.


What does the Golgi complex in animal cells do?

Put a marker on proteins to direct them to the right location. Therefore, the Golgi puts special glykoproteins on proteins or cleaves signal sequences off the protein.


What is the sequences of DNA that provides instructions for protein synthesis?

That is called a gene.


What directs newly synthesized protein to its target?

Protein targeting in the cell is carried out via endoplasmic reticulum (ER) and mainly exported by Golgi apparatus (through vesicles). Proteins that have signal sequences will be destined to the nucleus and other organelles. Secretion of proteins to the cell membrane and out of cell by secretory vesicles.


What can protein sequencing tell you about organisms?

Protein (amino acids,precisely) sequences yield much information about the function of the protein more than its species diversity.


DNA sequences that code for proteins are called what?

genes


What does a protein phosphatase actually do to end a signal transduction?

Protein phosphates turn off signal transduction pathways by removing the phosphate groups from the protein kinase, making them reusable and making the kinase inscribe stopping the signal transduction pathway.
