Answer:c. DNA polymerase can join new nucleotides only to the 3′ end of a pre-existing strand.

Explanation:

The double stranded molecule of DNA having the pairing strands in the anti-parallel condition. One strand is remain in configuration as the 5’ to 3’ end, the complementary strand is positioned 3’ to 5’ end.

New DNA strand synthesis occurs from the 3’ to 5’ end as the enzyme DNA polymerase attach itself to the 3’ end of a DNA strand. It will add new nucleotides to the 3' end of the DNA.

Hence, the option (c) is the correct answer.

What separates rabbits/primate from the crocodiles on this cladogram? 9. which organism is most related to the rodents and rabbi

GaryK [48]

Answer:

- According to the cladogram what separates rabbits/primates from crocodiles is that the former have a divergence before the latter and are viviparous.

- The organism that is most closely related to rodents and rabbits in the cladogram is the primate.

Explanation:

The cladogram (see image) shows the evolutionary line that several animal species have followed. According to this, the following conclusions can be established:

Both primates and rabbits/rodents are mammals, with intrauterine development of their offspring, while crocodiles and birds are oviparous, which represents a divergence in their evolution.
The species most related in the cladogram to rabbits / rodents is the primate, since they share several characteristics in common, such as being mammals, skin covered with hair and being viviparous.

Characteristics such as these are what allow the classification of different animal species.
