54 Biotechnology Demystified 6. A human gene: (a) codes for one protein. (b) consists of three organic bases. (c) depends on accurate translation by the RNA polymerase. (d) all are correct. 7. RNA polymerase: (a) makes mRNA (b) must bind to the DNA (c) assembles amino acids. (d) links amino acids together through peptide bonds (e) a and b are corect. (f e and d are correct. The code for a protein: (a) is called a gene. (b) contains nonessential information embedded in the code. (c) must be read out by RNA polymerase to make a functional protein. (d) usually requires excision of unnecessary code after the code is read out. (d) all are correct. 8. 9. Amino acids: (a) are usually coded by more than one sequence of bases. (b) are transported by messenger RNA to the DNA. (e) are assembled into proteins within the nucleus. (d) are held into place by the RNA polymerase. (e) all are correct 10. The DNA: (a) must be partially unwound before the genetic code can be read out. (b) contains the same amount of adenine as thymine. (c) contains the same amount of cytosine as guanine. (d) one strand dictates the composition of the opposite strand. (e) all are cormect.Explanation / Answer
6. A human gene :-
A human gene is DNA molecules. The DNA molecules are formed by four nitrogen bases. Adenine , thymine , cytosine and guanine.
So the correct option i s(a).
7. RNA polymerase:-
- makes mRNA
- must bind to the DNA , in order to form RNA molecules.
- it don't assemble amino acids , it forma RNA molecules from DNA .
- It doesn't link amino acid through peptide bonds.
Hence answer is option (c)
8. The code for a protien :
The correct option is option (a) is called a gene.
9. Amino acids are:-
The correct option is option (a) are usually coded by more than one sequence of bases.
10. The DNA
the correct ption is option(e) all the options are correct.
Hopefully it helps thanks .
