Answer:
tRNA and mRNA can leave the nucleus.
Explanation:
tRNA, when mature and correct, can leave the nucleus and enter the cytoplasm. mRNA can leave the nucleus through pores in the nuclear membrane. However, DNA cannot leave the nucleus, it has to be transcribed into RNA.
Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. ... Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.
Answer: B. Neurotransmitters; C. Enzyme components; E. Hormones
Explanation: Aminoacids have a variety of functions because they can create proteins. These long and complex molecules perform important roles in different biological processes: they are responsible for the formation of enzymes and hormones. In neurotransmitters, the glutamate appears to be related to functions of the brain, like learning and memory. Other functions of the aminoacids are regeneration of muscular cells, have a role in imunology, growth of tissue, production of collagen and others.
Answer:
The non- template strand will have the same sequence as the mRNA except, Thymine, T, will be replaced by Uracil, U, in the mRNA. The orientation will also be the same.
Hence, the mRNA sequence will be
5' AUGCCAGUCAUC 3'
This is because both the non- template strand and the mRNA are complementary to the template strand. Hence, they will have the same orientation as well as sequence except for thymine and uracil.
