The correct answer here is "cell membrane". Generally it makes sure that nothing enters or leaves the cell, except by its highly guarded "gates", such as ion channels, that let some particles through - but they're very picky about whom to let in!
I dont really understand where someone would get this information. was there a document or article you were supposed to read before this if so that would be very helpful.
Answer:
D-DNA molecule
Explanation:
The process of copying the sequence of DNA nucleotide sequences to the mRNA is called Transcriptions. It is the first stage in gene expression for protein synthesis, and<u> it involves the unwinding of the DNA double strands molecules by enzyme</u><u> </u>DNA Helicase into two free strands,(by melting the hydrogen bonds between organic bases), a process initiated by the binding of enzymes RNA Polymerase to the promoter sites on the DNA template; the alignment of the mRNA nucleotides on the single DNA template strands in 3'-5 direction; the formation of hydrogen bonds between the organic bases of the template DNA and that of the messenger RNA single strands,( and phosphodiesterbonds within RNA nucleotide ), to form DNA-RNA complex.
The copying is done in complimentary anti parallel fashion;5'-3' prime. direction.
The hydrogen bonds, between the bases DNA-RNA complexes breaks,and the releases the mRNA which exists through the nuclear pores.Thus this <u>leads to copying of the the coded messages as seqeunce of DNA , from the DNA to the mRNA for gene expressions.</u>
Answer:
Translation of genetic code for protein formation
Explanation:
Answer: A. environmental influences
A development in terms of biology is a gradual process of changes that occurs in an organism until the organism attains maturity or adulthood. Development can be physiological and mental development. Environmental influences are influences of nature on development. Some of the environmental influences are nutrition, altitude, temperature and climate. For example sunny weather conditions in a region can induce dark complexion in the habitants.
