Correct Answer: Uracil
Explanation:
A nucleotide is an organic molecule that is the building block of DNA and RNA. They also have functions related to cell signaling, metabolism, and enzyme reactions. A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine. RNA contains uracil, instead of thymine.
A nucleotide within a chain makes up the genetic material of all known living things.
Correct Answer: the complete set of an organism's genes and other DNA sequences
Correct Answer: a plasmid used to transfer DNA into a living cell
Explanation:
The term 'Vector' in recombinant DNA methods, refers to a plasmid or other agent used to transfer DNA into a living cell.
Correct Answer: All of the above
Explanation:
Major fructose sources include all fruits and honey.
Correct Answer: axon
Explanation:
Schwann cells or neurolemmocytes are the cells in the peripheral nervous system that form the myelin sheath around a neuron's axon.
Correct Answer: a segment of chromosomal DNA
Explanation:
Gene is a hereditary unit consisting of a sequence of DNA that occupies a specific location on a chromosome and determines a particular characteristic in an organism.
In short it is a piece or segment of chromosome.
Genes undergo mutation when their DNA sequence changes.
Correct Answer: Single?strand binding proteins stabilize the open conformation of the unwound DNA.
Correct Answer: Bronchi
Explanation:
Tubes that bifurcate from the windpipe are called Bronchi.
Correct Answer: It is used to transfer genetic information.
Explanation:
A RNA copy of a DNA gene is called as messenger RNA or mRNA. mRna is used in translation because information is translated from one language (nucleotides) into another (amino acids).
Hence, mRNA is used to transfer genetic information by a cell.
Correct Answer: Small intestine
Explanation:
The digestion process starts in the mouth and the complete digestion process completes in the small intestine where all the nutrients in the food are absorbed.
