Nonsense mutation. It is a type of genetic defect in which an amino acid codon is substituted by TGA, TAG, or TAA stop codon. A genetic code that indicates the end of protein manufacturing inside the cell is a stop codon. The three stop codons are nucleotide base triplets that present an integral role in intracellular protein synthesis.
Physiological and anatomical changes are ...

The sugar of RNA is much more reactive than the sugar of DNA. RNA is an acronym for ribonucleic acid, and it is a molecule made up of nucleotides, and it is found inside the cell structure. Each nucleotide in RNA is comprised of a nitrogen base, ribosomal sugar, and phosphate.
The nitrogenous RNAs include adenine, guanine, cytosine, and uracil, which replaces thymine in DNA. RNA is a ...

The largest animal is the blue whale at about 98 feet in length and 220 tons. When a baby blue whale is born, they weigh up to three tons and measure about 25 feet. After that, they will gain about two hundred pounds a day for the first year. They can grow up to up to one hundred feet and weigh up to two hundred tons.
Their hearts and other parts of the body are rather large, and the ...

The hairpin loop forms in an mRNA strand during transcription and causes the RNA polymerase to dissociate from the DNA template strand. This process is called intrinsic termination, and the participating sequences are called terminator sequences.
The Stem-loop or hairpin loop occurs when regions of the same strand, typically complementary in nucleotide cycle when read in opposite ...

RNA polymerase. In molecular biology, RNA polymerase is an enzyme that synthesizes RNA from a DNA template. RNA polymerase opens the double-stranded DNA so that one strand of the exposed nucleotides can be employed as a pattern for the synthesis of RNA, a process called transcription.
The transcription factor and its associated transcription mediator complex must be fixed to a DNA ...

Biology is a field of study. It is a type of science subject. This field of science studies organisms that are living, and they study the life of those organisms. It also studies chemical processes that occur in organisms. There are certain basic fundamentals that make up the study of biology. One is the cell theory. It states that the cell is the most important part of life.

The correct answer to this question is cellulose. Paper towels are made of fibers that are cellulose. The fibers are made from things like wood, cotton, and some other plants. The fibers are molecules are large and they are made of molecules that are small and linked together.
All of the small molecules are combined so that cellulose is formed. Sugar molecules are also formed. With ...

Proteins cannot store energy but they can do a lot of things that the body may need. For example, they are meant to do a lot of roles. For example, they would need to work closely with cells to make sure that the different organs of the body will be working properly.
They are also in charge of making sure that the functions of the body will be properly regulated. They are also ...

The one that is not a principle of the cell theory is that very few cells reproduce. This is one of the things that cells do. They will always reproduce. Actually, it is crucial that they will reproduce because if they do not reproduce, it will be hard for the different tissues and organs to survive.
There is a need for them to reproduce often so that there are always new cells that ...

Most people would call this person a botanist or a horticulturist. There are some people who may have a hobby of taking care of plants. You would call people like these gardeners because they normally love to tend to their gardens without a lot of effort.
Someone who would be called a “plantsman” can be someone who is obsessed with anything that is related to plants. There ...
