What do chromosomes do for a cell?
A chromosome is an organized structure of DNAand Proteinthat is found in Cell_(biology).Itis a single piece of coiled DNA containing many Gene, Regulatory_sequenceand other Genetic_sequence. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions.
How do DNAand RNAcode for proteins and determine traits?
DNA and RNA code for proteins through a process called transcription and translation. During transcription, DNA is transcribed into messenger RNA (mRNA), which carries the genetic information from the nucleus to the ribosomes. In translation, the mRNA is read by ribosomes, which synthesize proteins using transfer RNA (tRNA) that brings the appropriate amino acids. These proteins ultimately determine an organism's traits by influencing biological functions and processes.

Is DNA and chromosomes the same thing?
which plant? The chromosome count varies with the species of plant under consideration. Plants have also know to have multiple chromosome doublings - that is sudden creation of species which have 2 3 or even 4 times the proper number of chromosome in their cells. The most notable example of this is wheat.
What is heredity and how does DNA and chromosomes play a part in it?
heredity is the transmission of genetic characters from parents to offspring: it is dependent upon the segregation and recombination of genes during meiosis and fertilization and results in the genesis of a new individual similar to others of its kind but exhibiting certain variations resulting from the particular mix of genes and their interactions with the environment.DNA plays a part in heredity because genes correspond to regions within DNA, a molecule composed of a chain of four different types of Nucleotides-thesequence of these nucleotides is the genetic information organisms inherit. DNA naturally occurs in a double stranded form, with nucleotides on each strand complementary to each other. Each strand can act as a template for DNA_replicationa new partner strand. This is the physical method for making copies of genes that can be inherited.Chromosomes play a part in heredity because a chromosomeis an organized structure of DNAand Proteinthat is found in Cell_(biology). It is a single piece of coiled DNA containing many Gene, Regulatory_sequenceand other Genetic_sequence. Chromosomes also contain DNA-bound proteins, which serve to package the DNA and control its functions.
What is the role of magnesium?
Magnesium is an essential element in biological systems. Magnesium occurs typically as the Mg2+ ion. It is an essential mineral nutrient (i.e., element) for life and is present in every cell type in every organism. For example, ATP (adenosine triphosphate), the main source of energy in cells, must be bound to a magnesium ion in order to be biologically active. What is called ATP is often actually Mg-ATP. As such, magnesium plays a role in the stability of all polyphosphate compounds in the cells, including those associated with the synthesis of DNAand RNA.Over 300 enzymes require the presence of magnesium ions for their catalytic action, including all enzymes utilizing or synthesizing ATP, or those that use other nucleotides to synthesize DNA and RNA.In plants, magnesium is necessary for synthesis of chlorophyll and photosynthesis.
What are three ways that people use restriction enzyme?
Restriction enzymes (REN's) cut or cleve DNA. This cutting process is sequence-specific. Which means, the enzyme does not randomly fragment the DNA (or template strand as it is generally called in many experimental protocols). Instead, the enzyme scans the length of the template until it reaches a specific sequence of 4 - 8 nucleotides. Once this sequence (the restriction site) is reached, the enzyme produces a cut in the template and generates either blunt ends (no overhangs) or sticky ends (having both 3' and 5' overhangs) The primary application of restriction enzymes is is genetic engineering where we want to insert cDNA sequences into plasmids or other vectors.
