c-  a protein coding sequence  

Gene is the functional unit of heredity and  functional unit of Gene is DNA because genes are made up of DNA. In  molecular terms, a gene commonly is defined as the entire nucleic acid sequence that is necessary for the synthesis of a functional polypeptide or a protein. So gene gives instructions to form a protein with the help of RNA.

Prions are best described as —— 1)complete virus particle? 2)DNA molecules preotected by dna shell? 3)infectious rna molecules? 4)Self-replicating misfolded protiens?

The correct option is 4). Prions are self-replicating misfolded proteins.

Briefly explain the four levels of protein structure. In your answer refer to a protein haemoglobin and catabolite gene activator protein where applicable.

Protein primary structure is the sequence of amino acid residues linked by peptide bonds in the polypeptide chain.Protein secondary structure is the local ordering of a polypeptide chain fragment stabilized...

3.2 Briefly explain the four levels of protein structure. In your answer refer to a protein haemoglobin and catabolite gene activator protein where applicable.

The four levels of protein structure are primary, secondary, tertiary, and quaternary.Specific order of amino acid linked by peptide bond forms a primary structure.Polypeptides bend and fold to form a three-dimensional shape...

Examine the differences between DNA and RNA. Explain why DNA is the most favorable molecule for genetic material and how RNA compares to it in this respect.

1. DNA is a double helix, with two chains bonded together and twisted, and RNA is a single helical molecule,with only one chain twisted. 2. DNA has the base Thymine...

How does protein form? Explain how different bonds contribute into protein hierarchical structure. Give one example which demonstrates four protein structures.

In the process of translation, a protein is synthesized based on m-DNA. After protein synthesis, posttranslational modifications (covalent chemical and enzymatic modification of the protein, protein splicing, protein folding) begin...

why does the change in only one DNA base of a gene does not always result in a different protein being produced by the gene

CHANGE IN DNA BASE GENEAbstract: Base substitution involves swapping one nucleotide for another during DNA replication, base substitution can lead to three different sub-categories of mutation; missense, nonsense and silent...

Definition of cryptic satellite DNA: A satellite DNA sequence that cannot be separated from the main-band DNA by density gradient ultracentrifugation. What's the meaning of main-band DNA.?

Main-band DNA is the DNA sequences, which do not contain the satellite DNA or other repeated sequences. It is the empirical name, which was given to bands on electrophoregram, which...
