How does DNA direct activity in the cytoplasm?

Answer 1

Indirectly by the diverse substances that control the expression [or 'silencing'] of the DNA sequences that produce messenger Rnas, that then propel the 'said info' to the Ribosomes which then produce the enzymes.

Answer 2

Coding for amino acids occurs based on DNA base sequences in groups of three. There 64 three base combinations, three that are "stop" codons and the remaining 61 that code for amino acids to produce various proteins. An online search or search of this site will yield a table showing which base sequences are associated with each amino acid. Since there are so few amino acids relative to base combinations there are many "codes" that produce the same amino acid.

Answer 3

No, in an eukaryote*, DNA will never leave the nucleus. Its code is carried past the nuclear envelope to the ribosomes through an intermediate, mRNA (messenger RNA). The reason for this is primarily because the cytoplasm is rife with hydrolytic enzymes that would degrade the DNA once outside of the nucleus. If the DNA is destroyed, then the cell is out of luck and it will cease to function.

* Note that prokaryotes do not have a nucleus; thus, protein synthesis does occur in the cytoplasm.

Answer 4

First of all, we should think in the making of proteins, or protein synthesis, as a process divided into very defined steps or stages. The first stage starts with the DNA. This outstanding molecule keeps the "biological information" within it, as we know, the genes. In general terms, a gene can be defined as a particular sequence of nucleotides with a defined length. This gene or sequence has to be "copied" into a molecule called messenger RNA. or mRNA, in a process known as transcription. mRNA molecule will serve as "template" for the new protein molecule that is going to be built. The sequence of nucleotides, every three of them, called "codons", will guide the formation of the new protein molecule in a process called "translation". In resume, DNA starts the making of a protein molecule from its nucleotide sequence that will be translated into an amino acid sequence, the monomers of a protein molecule.

Answer 5

DNA directs activity in the cytoplasm through the process of transcription and translation. DNA is transcribed into messenger RNA (mRNA) in the nucleus, which then moves to the cytoplasm where it is translated into proteins with the help of ribosomes and transfer RNA (tRNA) molecules. These proteins carry out various functions in the cell, directing its activities in response to the instructions encoded in the DNA.

Answer 6

Not directly. DNA codes for an RNA transcript which directs the production of a protein.

Answer 7

Yes and the process is called protein synthesis

Answer 8

the rna polymerase attaches and copies an rna version of the dna and the messenger rna enters a ribosome which uses the amino acids as instructions for making the protein.

Answer 9

It helps with the movement of the cell
