Answer:
A single nucleotide polymorphism (SNP) is the most common gene variation found among people. A SNP represents a change in a single DNA block, called a nuecleotide, being able, for example, to replace a nucleotide cytosine (C), with a nucleotide thymine (T), guanine (G) or adenine (A) in the genome. They represent the 90% of all the human gene variations.
Explanation:
Answer:
E. rER \to Golgi \to secretory vesicle \to environment
Explanation:
A protein that is normally localized in the cytoplasm has been engineered so that it will be secreted from the cell instead will follow the following sequence:
Rough endoplasmic reticulum (RER) (where the protien is being snthesized)-------------> Golgi apparatus (where the sorting and packaging of the protien occurs)-----------------------> Secretory vesicles-------------------------> Environment.
Hence E. rER \to Golgi \to secretory vesicle \to environment is the right answer.
The sequence of the mRNA complementary strand for the given sequence of the strand will be 'AUG CUU GAG GGG UCC'.
The name of the decoding process is translation, and ribosomes are involved in this process.
The process of the synthesis of protein begins with the process of transcription. In this process, the DNA is unwinded, and the RNA polymerase binds to the promoter region and transcribes the codon corresponding to the amino acids. The transcribed mRNA strand is then translated by the ribosomes. The ribosomes reads the codons and the tRNA brings and attaches the related amino acids in a sequence resulting in the formation of a protein.
The protein synthesis is crucial as the proteins are responsible for the structure and functions of the different cells of the body.
Sickle cell anemia is a genetic disorder, in which a point mutation changes the codon for the glutamic acid to valine. This leads to the formation of an abnormal shape of the hemoglobin which decreases the ability of it to efficiently transport oxygen.
