Question

When binary fission occurs, name the type of nucleic acid much information is copied. of nucleic acid involved and how What is the difference between binary fission and protein synthesis: What is meant by "complementarity of bases? What are nucleotide bases? Name the nucleotide bases associated with DNA with RNA. How many nucleotide bases are necessary to code for one amino acid? Name the two different classes of genes. Structural Regulaory What are constitutive enzymes? What are inducible and repressible enzymes?

Answer 1

1. DNA is involved and one copy of DNA is copied

2. binary fission is an asexual mode of reproduction, Replication of DNA take place and protein synthesis is machinary by which protein synthesis take place.

3.nucleotides opposite to original template strand are as complementary bases

4. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).

5.3 nucleotides (triplet codon) codes for an amino acid

6.structrual genes and regulatory genes

7.constitutive enzymes are always present our in constant levels regardless of metabolic State,

inducible enzymes ia an enzyme whose rate of activities can controlled by inducer.

repressible enzyme an enzyme whose production is generally continuous but can be halted if a particular substance is present in concentrations greater than normal
