Molecular Biology

Molecular biology is the study of how molecules (biomolecules such as protein, DNA) communicate in the cell and how the field helps to study them in a external condition.

What are RNA four bases?

RNA are ribonucleic acids that are transcribed from DNA. Unlike DNA, RNA is made up of adenine, guanine, cytosine and uracil (instead of thymine). Although cellular RNA are single stranded they do form secondary structures by interacting intermolecular regions and produce stem loop structure (tRNA is an example)

What has the author Dale Andrew Ramsden written?

Dale Andrew Ramsden has written:

'Recombination and repertoire: the molecular biology of V(D)J rearrangement, and how V(D)J rearrangement affects B cell development and the B cell repertoire'

What has the author Geoffrey Harvey Haggis written?

Geoffrey Harvey Haggis has written:

'The electron microscope in molecular biology'

What finding changed the central dogma of molecular biology?

The discovery of reverse transcriptase was a key finding that changed the central dogma of molecular biology. This enzyme allows RNA to be transcribed into DNA, reversing the flow of genetic information in some viruses. This challenged the traditional concept that genetic information flows only from DNA to RNA to protein.

What are some examples of chiral molecules?

Chirals molecules have a non-superimposable mirror version composed of the same amounts of atoms. Famous examples are Alaine, with a R and S zwitterion, 2-Bromo-2-Hydoxyethanol and 2-Chloro-2-propanic acid and 2-Amino-Pentane and Valine and Carvone and 2-Butanol and 1-Iodopropanol,

How are molecules in wood arranged?

molecules are arranged in good order along the fibers

Why the marker lanes are used during electrophoresis?

The marker lanes are important in electrophoresis because in these lanes peptides or proteins with known molecular sizes and weights (standards) run beside, on the same gel, with the sample and the Rfs (relative mobilities) of the developed bands of the unknown proteins can be compared with those of the standards.

What is the high energy molecule that supplies fuel for cells?

  1. glucose is the primary chemical that supplies energy to a cell
  2. adenosine triphosphate (ATP) is the chemical that storesenergy for direct use by a cell
Glucose and other chemicals that supply energy to a cell are metabolized (either by aerobic respiration or anaerobic fermentation) to manufacture ATP, which the cell can then use directly as it needs energy.

Can a receptor be an antigen?

No, they are entirely two different things. What might stimulate a receptor could be an antigen.

What cells require glucose as an energy to carry out life processes and what mediates the glucose transport across the cell's plasma membrane?

Glucose is virtually the sole energy fuel of brain. Where as, Muscle can derive energy from glucose, fatty acids and ketone bodies; adipose tissue stores and uses triacylglycerols.
Glucose transporters in the cell membrane permit the entry of glucose inside the cells.

How many unit eyes does a fruit fly have?

A fruit fly, also known as Drosophila Melanogaster, has two compound eyes that are each made up of 800 unit eyes. These unit eyes are called ommatidia. Each ommatidium (sing.) contains eight photoreceptors labeled R1-R8.

Site directed mutagenesis is a molecular biology method used to make what?

Site directed mutagenesis, also called site-specific mutagenesis or oligonucleotide-directed mutagenesis, is used to make specific, intentional changes to the DNA sequence of a gene and/or gene products. It is used to investigate the structure and biological activity of RNA, DNA, and protein molecules. Also used for protein engineering.

What is the opsin protein?

The opsin protein is part of a superfamily of G-protein coupled receptors. Each protein in this family has seven transmembrane domains and is found within the plasma membrane. The genome of seeing animals contain various opsin genes. Each have different properites - the different rhodopsins in which they are found can capture light in different wavelengths.

Is the embryo of a pig and calf part of molecular biology?

Is the embryo of a pig and a calf part of the molecular biology

How many molecules are in a pie?

Too difficult to even try to estimate as pies are of many different sizes, pies are mixtures that vary practically infinitely in possible ingredients that can come in widely varying amounts, the molecules in pies vary from small ones (e.g. water) to gigantic polymer molecules (e.g. starches, celluloses, proteins, DNA, RNA), etc.

Perhaps if you reworded your question to identify a specific size and type of pie someone might be able to give you an estimate that might be within a couple of orders of magnitude of the actual number.

Cellular adhesion molecules are?

Cell adhesion molecules are groups of transmembrane proteins that mediate.

What is a DNA related to gene?

A segment of DNA that makes up a gene which may codes for a particular product.

What is full form of ismb?

Intelligent Systems for Molecular Biology.
