The average molecular weight of proteins encoded in the human genome is about 50,000. A few proteins are very much larger than this average. For example, the protein called titin, which is made by muscle cells, has a molecular weight of 3,000,000. Estimate how long it will take a muscle cell to translate an mRNA coding for an average protein and one coding for titin. The average molecular mass of amino acids is about 110 daltons. Assume that the translation rate is two amino acids per second.
Answer:
13,636 seconds = 227.3 minutes = 3.79 hours
Explanation:
The titin protein has a molecular weight of 3,000,000 daltons, while the average molecular mass of one amino acid is 110 daltons, so it is expected that this protein is composed of 27,273 amino acids (3,000,000 daltons/110 daltons = 27,272.72). Moreover, and since the translation rate is two amino acids per sec, it is expected that the protein will be synthesized in approximately 3.79 hours (27,272.72/2 = 13,636 seconds = 227.3 minutes = 3.79 hours).

The modern cell theory doesn't say
A all living things are multicellular
B cells are the smallest living unit in all organisms
C all cells come from other cells
D all living things are made of cells
Answer:
A
Explanation:
Modern cell theory states: cells are the basic unit of structure and function for all living things, all cells come from preexisting cells, and all living things are made from cells. It does not state that all living things are multicellular, in fact there are plenty of unicellular organisms. Therefore the answer is A.

Some people's earlobes dangle or flap unattached, while others don't. This trait is genetically determined. Use the genetics simulation to explore the genes that determine whether earlobes are attached or unattached. One trait is dominant and the other is recessive. See what happens when you cross parents with different genetic combinations. Follow the specific instructions for each trial.

Which of the following would be affected when a protein is denatured?
a.) amino groups
b.) primary structure
c.) side chains
d.) tertiary structure
"b" why because primary structure needs protein and if protein denatured,primary structure will affected instantly!
#followandheartallmyquestion
When a protein is denatured by chemical, heat or other substances, the primary structure remains intact. Hence, the correct answer would be the tertiary structure.
Denaturation of proteins generally causes the breakage of weak bonds on which the folding and the entire protein structure is built. When this happens:
the peptide bonds between the component amino acids remain intact. Hence, the primary structure is conservedthe destruction of other bonds means that the secondary and tertiary structures are affected.Agents that are capable of denaturing proteins include high temperature, changes in acidity/basicity, UV radiation, high concentration of salts, and so on.
The correct answer as to which would be affected when a protein is denatured in this case would, therefore, be the tertiary structure.

If u looked at a SA cells and cardiac muscle cells under a microscope, do u think they would look the same or different from each other? Explain ur reasoning HELP MEE PLSSSSS
Answer:
They look a little bit different. SA cells contain fewer mitochondria, fewer myofibers, and a smaller sarcoplasmic reticulum. This means that the SA node cells are less equipped to contract compared to the atrial and ventricular cells.
what are the the four main categories of organic macromolecules ?
Answer:
There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions.
Four main categories of organic macromolecules are as follow:
carbohydratelipidsproteinsnucleic acidWhat are macromolecules?Macromolecules are polymers containing long chains of molecular sub-units known as monomers. These play an important role in biophysical processes and composed of thousands of atoms that are covalently bonded.
Carbohydrate is a biomolecule having carbon, hydrogen and oxygen atom.It is the main source of energy of the body.
Lipids are macromolecules that are insoluble in water and the main function is to serve as structural component of cell membrane.
Proteins are macromolecules that are extremely complex in structure and made up of amino acid residues joined by peptide bonds.
Nucleic acids are biopolymer macromolecules and composed of nucleotide. The function is to carry genetic information which helps to make RNA.
