What is the relationship between the nucleolus ribosomes and proteins?
Nucleolus makes ribosome parts, which makes proteins.
What is the correct pathway of information flow in the cell?
Information is picked up from the dendrites and then transfered to the soma (which is through action potentials) and then transfered to the axon which then goes to the presynaptic terminals that sends the information to the next neuron which will then repeat this flow of information.
Carries the message of DNA to ribosomes?
mRNA (messenger RNA) carries the instructions for protein synthesis from the DNA to the ribosomes.
What is a reterovirus?
A retrovirus is an RNA virus that is replicated in a host cell via the enzyme reverse transcriptase to produce DNA from its RNA genome. The DNA is then incorporated into the host's genome by an integrase enzyme. The virus thereafter replicates as part of the host cell's DNA. Retroviruses are enveloped viruses that belong to the viral family Retrovirida.
Describe the process of transcription in biology?
This process occurs in the nucleus of a cell. Firstly DNA helicase, will break the hydrogen bonds holding together the two strands of DNA. This exposes the bases on the two strands. RNA polymerase then anneals free nuleotides via phosphodiester bonds, via complementary base pairing to one strand of DNA, known as the template strand. Thus a strand of pre-messenger RNA is built, as the RNA polymerase moves along the DNA strand, the two DNA strands join up behind it. RNA polymerase stops the process of transcription when it reaches stop codons, which tell the enzyme to stop annealing nucleotides. The product is a length of pre-mRNA, which can then leave the nucleus throguh the nuclear pores and undergo splicing to remove introns and then translation.
What is a collection of cells containing DNA fragments produced by restriction enzymes and incorporated into plasmids?
A DNA LibraryA collection of cells containing DNA fragments produced by restriction enzymes and incorporated into plasmids is called a DNA library. RNA can manufacture DNA via the action of reverse transcriptase.

What is a major distinction between a transposon and a retrotransposon?
A transposon moves via a DNA intermediate and a retrotransposon via an RNA intermediate.

How do the nucleotides in DNA change?
I don't think they do. RNA changes to DNA when an oxygen atom is removed from the ribose portion of a ribonucleoside diphosphate to make a deoxyribonucleoside diphosphate, via the action of rNDP reductase. http://www.weegy.com/?ConversationId=8907A43Q
What is a basepair?
A basepair is a pair of nucleotides on opposite complementary DNA or RNA strands which are connected via hydrogen bonds.
Carries the message of DNA to ribosomes?
mRNA (messenger RNA) carries the instructions for protein synthesis from the DNA to the ribosomes.
Why is RNA needed to create proteins?
RNA is a single-stranded structure that is copied from an unzipped DNA strand identically, this is called transcription. The RNA strand contains the complementary base pairs for the DNA sequence. The DNA strand has sections that code for specific proteins, so when the RNA strand is created from the DNA, the RNA strand is then able to recreate the sequence that codes for the proteins. The RNA strand leaves the nucleus, via a nuclear pore, and enters the cytoplasm. In the cytoplasm the RNA strand binds to two Ribosomal subunits, and translation is carried out, producing proteins.
What enzyme joins the nucleotides of a DNA strand together?
That depends on the process. During DNA replication, The nucleotides of the lagging strand (Okazaki fragments) are connected by DNA ligase. In transcription, the nucleotides of RNA are connected by RNA polymerase II.DNA Polymerse
How does RNA work together with DNA?
Ribosomal RNA or rRNA is the main constituent of ribosomes. It performs the peptidyl transferase function of combining amino acids together via peptide bonds.
