T_roy- Week 5- DNA

Which is not characteristics of DNA molecule:

• Double helix.

• The two strands in a DNA are antiparallel.

• Has sugar-phosphate backbone.

• A pairs with U, G pairs with C.

The process to transfer genetic information from DNA into an RNA molecule is called ____________________.

The process to synthesize a protein from the instructions in mRNA is called _______________________.

If a parental DNA strand has the base sequence A-T-T-G-C-A-C-T, in DNA replication DNA polymerase would synthesize a new strand with the sequence:

• A-T-T-G-C-A-C-T.

• T-A-A-C-G-T-G-A.

• C-G-G-T-A-C-A-G.

• The sequence of the new strand cannot be determined from the information given

Which one is component of DNA nucleotide?

• A phosphate group

• A deoxyribose sugar

• A nitrogen-containing base

• A ribose sugar

An DNA molecule has in total 2000 nucleotides. Knowing that there are 300 Adenine nucleotides. How many nucleotides of Cytosine? Write only the number in the answer.

The genetic code: three amino acids represent one nucleotide.

• True

• False

The process to duplicate the parent cell DNA is called replication.

• True

• False

DNA mutation is infrequent changes in the nucleotide sequence of DNA.

• True

• False

When two Adenine is replaced by two Guanine in the DNA sequence, the mutation is called.............
