Answer:
DNA plasmid that contains both "old" and "new" gene segments and confers new characteristics to the organism in which it is placed.
Explanation:
During the genetic engineering procedure, which aims at producing an organism with better and desirable characteristics, a DNA called PLASMID is usually used to convey the gene of interest into the organism.
A plasmid is a self-replicating extra-chromosomal DNA found in the bacterial genome. The plasmid becomes a RECOMBINANT PLASMID when a foreign DNA of interest is inserted into it, in order to act as a vector (carrier). Therefore, a recombinant plasmid is a DNA plasmid that contains both "old" i.e bacterial genome and "new" i.e foreign gene segments and confers new characteristics to the organism in which it is placed.
A molecule is a group of two or more atoms held together by chemical bonds. A compound is a substance which is formed by two or more different types of elements which are united chemically in a fixed proportion. All molecules are not compounds. All compounds are molecules.
Answer:
. A DNA molecule in a human chromosome can be up to 250 million nucleotide-pairs long; in contrast, most RNAs are no more than a few thousand nucleotides long, and many are considerably shorter.
Answer:
NH2 group combines with COOH group to form CONH group after releasing water
Explanation:
A peptide bond is formed between two R groups of amino acids by eliminating a molecule of water. If two amino acid joins, then a dipeptide link is formed. When three amino acid joins, then a tripeptide link is formed. And in case when many amino acid joins, then a polypeptide link is formed. A protein chain usually has several amino acid residues ranging from 50 to 2000 in numbers. Since a polypeptide chain is formed after the removal of water , it is known as amino acid residues.
Generally , NH2 group combines with COOH group to form CONH group after releasing water
