What is the name of the family of DNA binding proteins that function to package DNA into chromatin?
histones are the proteins that compact and order DNA into subunits in the first step of the making of chromatin
Can mercuric chloride denature protein?
Yes, mercuric chloride can denature proteins by disrupting their structure through binding to thiol groups present in amino acids such as cysteine. This binding can lead to protein misfolding and loss of function.
Proteins that function as chemical messengers?
Examples of proteins that function as chemical messengers include hormones like insulin and growth factors. These proteins are released by specific cells to communicate with target cells, regulating various physiological processes such as metabolism, growth, and development. By binding to specific receptors on the target cells, these messenger proteins can trigger a cascade of molecular events leading to specific cellular responses.
What are the functions of rRNA?
The primary function of rRNA is in protein synthesis – in binding to messenger RNA and transfer RNA to ensure that the codon sequence of the mRNA is translated accurately into amino acid sequence in proteins. The function of rRNA is to serve as a location for protein synthesis. rRNA is the location in which mRNA and tRNA are able to come together to synthesize proteins.
Eukaryotic are controlled by what group of proteins?
Eukaryotic cells are controlled by a group of proteins called transcription factors. These proteins regulate the transcription of genes by binding to specific DNA sequences and influencing the expression of those genes. They play a crucial role in gene regulation and cell function in eukaryotic organisms.
What is the name of the family of DNA binding proteins that function to package DNA into chromatin?
histones are the proteins that compact and order DNA into subunits in the first step of the making of chromatin
What is the function of single strand binding proteins in DNA replication?
Single strand binding proteins in DNA replication help stabilize and protect the single-stranded DNA during the process, preventing it from forming secondary structures or being degraded.
What what is the function of a 'hydrophobic island' on the surface of a protein?
These are called hydrophobic patches. They are frequently involved in recognition and binding of ligands and other proteins.
Function of binding buffer?
When alkali or acid is added to a pH solution, a binding buffer will help prevent the pH from changing. There is also the elution buffer which is used to clean out any proteins which are leftover.
How do dna-binding proteins in prokaryotes regulate genes?
Clever mechanisms turn genes off and on so that they only function when there is a need for their services
What type of proteins require a covalent bonded prosthetic group to function properly?
Proteins such as haemoglobin and myoglobin which require haem groups covalently bonded to the proximal histidine (HisF8) residue for O2 binding.
Can mercuric chloride denature protein?
Yes, mercuric chloride can denature proteins by disrupting their structure through binding to thiol groups present in amino acids such as cysteine. This binding can lead to protein misfolding and loss of function.
What has the author N Ulfig written?
N. Ulfig has written: 'Calcium-binding proteins in the human developing brain' -- subject(s): Molecular neurobiology, Calcium-binding proteins

What does the binding of regulatory proteins to DNA do?
Regulate gene transcription.
Are proteins hydrophobic and how does this property affect their function within biological systems?
Proteins can be both hydrophobic and hydrophilic, but their hydrophobic regions play a crucial role in their function within biological systems. These hydrophobic regions help proteins fold into their proper three-dimensional shapes, which is essential for their specific functions. Additionally, hydrophobic interactions between proteins and other molecules can drive important biological processes, such as protein-protein interactions and membrane binding.
What keeps intracellular receptors from binding to DNA?
chaperone proteins (chaperonins)
