It's a region of DNA that binds DNA Polymerase to begin replication.
Answer:An explosion disturbs the gas and dust in the nebula.
Explanation: Scientists believe that the solar system was formed when a cloud of gas and dust in space was disturbed, maybe by the explosion of a nearby star (called a supernova). This explosion made waves in space which squeezed the cloud of gas and dust. Squeezing made the cloud start to collapse, as gravity pulled the gas and dust together, forming a solar nebula . Just like a dancer that spins faster as she pulls in her arms, the cloud began to spin as it collapsed. Eventually, the cloud grew hotter and denser in the center, with a disk of gas and dust surrounding it that was hot in the center but cool at the edges. As the disk got thinner and thinner, particles began to stick together and form clumps. Some clumps got bigger, as particles and small clumps stuck to them, eventually forming planets or moons . Near the center of the cloud, where planets like Earth formed, only rocky material could stand the great heat. Icy matter settled in the outer regions of the disk along with rocky material, where the giant planets like Jupiter formed. As the cloud continued to fall in, the center eventually got so hot that it became a star, the Sun, and blew most of the gas and dust of the new solar system with a strong stellar wind. By studying meteorites , which are thought to be left over from this early phase of the solar system, scientists have found that the solar system is about 4,600 million years old!
The perirhinal cortex is particularly important in visual recognition and receives more input from the occipital lobe than from other cortical areas. In addition, the perirhinal cortex is a cortical region in the medial temporal lobe that is made up of Brodmann areas 35 and 36. It obtains highly administered sensory information from all sensory regions and is usually accepted to be a significant region for memory.
The correct answer is C. Virus.
Virus falls on the gray area which is between nonliving and living things.
Virus is referred to as the small infectious agent which replicates only inside the living cells. Virus can infect life forms plants and animals and microorganisms, for example, archaea and bacteria.
They live in form of independent particles which are referred to as virions. Some viruses can evolve from plasmids.
<u>Answer:</u>
Point mutations occur when only one nucleotide is altered affecting only one location or point of the DNA strand.
While Frameshift mutations are caused by the deletion or insertion of a number of nucleotides.
These altered nucleotides affect the triple nature of gene expression disturbing the whole reading frame. All the codons after mutation are different translating a completely different protein. That's why frameshift mutations cause more problems than point mutations.
