Answer:
Both leading and lagging strands
Explanation:
DNA replication is the enzyme of DNA replication that forms new DNA strands. However, the enzyme cannot start the process of synthesis of new DNA strands by itself but needs small primers. Primers are the small RNA sequences synthesized by RNA primase on both leading and lagging strands.
These primers are elongated by DNA polymerase by the addition of deoxyribonucleotides according to the sequence of the template strand. Since DNA replication on both lagging and leading strand is carried out by DNA polymerase, RNA primers are present on both lagging and leading strands.
A) Discuss the anatomical changes that occurred in the bipedal hominin
The changes that occurred are the loss of the capability in hands to grasp on branches. This is because of the presence of an opposable thumb. Another change is the loss of walking on 4 legs. The hominids started to have an upright posture, have long legs and walk on their two feet.
b) How they reflect habitat adaptation
The species lived in wooded areas like forests. This is why they required the grasping abilities on their feet and hands to be able to move in the trees while holding branches. Shifting to unwooded areas like the grasslands made them lose some of their abilities. This is because they were no longer needed.
c) Discuss the hypothesis that propose why the change occurred.I
It was necessary for change to occur due to the fact that forests were becoming fragmented and patchy. Food also became dispersed and scarce. This made the species use more energy to get food and also have free hands for them to be able to pick up food. They also gained an upright posture.
d) How can 3D scans and printing be applied to other areas of science.
3D scanning has been used to scan many objects from different museums. It has also been used to identify the age of fosils and artifacts. 3D printing can be used to create prototypes in scientific technology research. It is also used to analyse features of objects.
e) What applications can they have
3D scanning and printing has been applied in architectural surveys to provide accurate measurements increasing on productivity and saving on time. It has also been used in health to create a detailed study of body parts and produce comfortable prosthetic limb for patients.
Answer:
CGC AUA CCG - RNA
CGC ATA CCG - DNA
Explanation:
Uracyl (U) is present in RNA instead of Thymine (T)
Also opposite RNA/DNA molecules pair with each other.
Adenine pairs with Uracyl (RNA)/Thymine (DNA)
Cytosine pairs with Guanine (both RNA & DNA)
