Where and what form is eukaryotic DNA found?
Where and what form is eukaryotic DNA found?
Where and in what form is eukaryotic DNA found? It’s found in the cell nucleus of a eukaryotic cell as chromosomes. How are the long DNA molecules found in eukaryotes packed into short chromosomes? DNA is wound tightly around histones and form nucleosomes.
What is the name for the process that copies a sequence of DNA nucleotides into a complementary sequence of RNA nucleotides?
Transcription
What are the tips of eukaryotic chromosomes called?
To prevent the loss of genes as chromosome ends wear down, the tips of eukaryotic chromosomes have specialized DNA “caps” called telomeres. Telomeres consist of hundreds or thousands of repeats of the same short DNA sequence, which varies between organisms but is 5′-TTAGGG-3′ in humans and other mammals.
What principle states that hydrogen bonds can form only between certain bases in DNA?
base pairing
What are these unpaired bases called?
Each transfer RNA (tRNA)) molecule has three unpaired bases called the anticodon. They are complementary to one mRNA codon. The tRNA will read the codon and deliver the correct amino acid to the right spot to build or synthesize the protein.
What are the 5 steps of translation in order?
Translation (Protein Synthesis)
- Initiation. In this step the small subunit part of the ribosome attaches to the 5′ end of the mRNA strand.
- Elongation.
- Termination.
What are the steps of translation protein synthesis?
Stages of Translation in Protein Synthesis
- Initiation: Ribosomal subunits bind to mRNA.
- Elongation: The ribosome moves along the mRNA molecule linking amino acids and forming a polypeptide chain.
- Termination: The ribosome reaches a stop codon, which terminates protein synthesis and releases the ribosome.
What is created by Translation?
The entire process is called gene expression. In translation, messenger RNA (mRNA) is decoded in a ribosome, outside the nucleus, to produce a specific amino acid chain, or polypeptide. The polypeptide later folds into an active protein and performs its functions in the cell.
What is the end result in protein synthesis?
The end result of translation in protein synthesis is a newly made protein. During transcription, DNA is copied to messenger RNA (mRNA) in the nucleus. When a stop codon is reached in the mRNA, the ribosome releases the polypeptide chain, which can then fold to form a protein.
What is created as a result of translation?
The molecule that results from translation is protein — or more precisely, translation produces short sequences of amino acids called peptides that get stitched together and become proteins.
What is another name for production of RNA by reading the DNA code quizlet?
The process by which the genetic information encoded in DNA is copied into messenger RNA (mRNA) is called transcription.
What is the end result of the translation portion of protein synthesis quizlet?
what is the end product of translation? opposite nitrogenous bases, and instead of thymine it’s uracil because it’s RNA. opposite nitrogenous pairs, and instead of thymine it’s uracil because it’s RNA. use mRNA for the nitrogenous bases on the codon chart.
What is found at the site of protein synthesis?
Ribosomes are the site of protein synthesis, and they convert the coded information in messenger RNA (mRNA) into an actual protein molecule. The mRNA molecule carries the message contained in your DNA to the ribosome.
What are the two steps of protein synthesis and where do they occur?
Protein synthesis can be divided broadly into two phases – transcription and translation. During transcription, a section of DNA encoding a protein, known as a gene, is converted into a template molecule called messenger RNA (mRNA).
Which of these is the primary site of protein synthesis quizlet?
Proteins are synthesized at ribosomes.
