Me answer these questions you so much in a hurry 1. if a segment of one strand of dna molecule has 234 adenine bases, how many cytosine bases does the other strand have? a 0 b 234 c 117 d there is not enough info to answer 2. the central dogma of biology states that a an rna molecule attaches to the dna b enzymes unwind the dna molecule in two strands c the dna leaves the nucleus d dna polymerase adds in new nucleotides 3. which process would follow dna replication? a dna replication b mitois and cell divsion c rna replication d celluar resprition

1.The correct answer is: D - There is not enough info to answer

This can be explained via Chargaff’s rule. Chargaff’s rule states that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine the (1:1 ratio of complementary bases).  

But, since we have information only for one strand of DNA’s adenine we cannot determinate how many cytosine bases does the other strand have.

2.The central dogma of molecular biology can be  shortly defined as: Transcription of DNA to RNA which is then translated into proteins. So, none of the answers is correct.

Central dogma is an explanation of how genetic information flow within the living cell (DNA-RNA-protein).The central dogma includes transfer such as:

•DNA to DNA (DNA replication)

•DNA to RNA (transcription)

•RNA to proteins (translation).

It is firstly stated by Francis Crick.

3.The correct answer is: B - mitosis and cell division

Replication of DNA occurs in the S phase of interphase-first stage of cell division. After the growth, replication and preparation, cell is ready to enter the M phase (mitosis or meiosis, depending on type of cell). After the M phase, cell undergoes cell division through cytokinesis (physical separation of two daughter cells). Before each phase, there is a checkpoint where the cell is checked and controlled in order to progress or deny further development.

the rocks are classified by the geological process they are formed by. the three main groups of rocks are igneous, metamorphic, and sedimentary. minerals are not they are classified under the chemical classes they are in. these groups include silicates, sulfates and carbonates.
