MRNA: AUG AAU UUA GCG ACA
polypeptides: Met or start, Aan, Leu, Ala, Thr
1. The type of mutation that occurred in this strand of DNA is deletion. This may have happened because a small part of the DNA sequence was lost when broken ends were rejoined when the DNA was being repaired.
2. It is not likely that these mutated genes could produce a working protein because the polypeptides were completely changed, which would cause the protein to not work properly.
3. When a seed first absorbs water, it begins to grow. The mutation could cause the plant to be unable to absorb water. Therefore, the plant would be unable to germinate.
Autobiographical memory refers to memory of specific events that had occurred during the course of one' lifetime. Autobiographical memory is divided into two major groups which are episodic and semantic memories. Episodic memory recollects time, location and people while semantic memory recollect general facts. An example of autobiographical memory is the memory of college graduation event.
Answer:
Natural selection can be described as a phenomenon in which individuals of a population which are better adapted to survive in an environment are favored by nature as compared to the individuals of the population which lack better characteristics to survive in the environment.
Through natural selection, evolution occurs and the allelic frequency changes over a period of time. The process of evolution as well as change in the allelic frequencies does not occur just by a single individual, rather it is a collective effort which takes a lot of time. Hence, we say that natural selection changes the population and not a single individual.
A male with a mutation in a gene on the X chromosome is typically affected with the condition. Because females have two copies of the X chromosome and males have only one X chromosome, X-linked recessive diseases are more common among males than females.
