What else can I help you with?
Contains its own DNA and ribosomes?
Mitochondria contain their own DNA and ribosomes, allowing them to carry out the process of protein synthesis independently of the cell's nucleus. This is thought to be a result of their evolutionary origins as symbiotic bacteria within eukaryotic cells.
Why are mitochondria able to make their own protein?
Mitochondria have their own DNA and ribosomes, which allow them to synthesize some of their own proteins independently of the cell. This ability is thought to have evolved from an ancient symbiotic relationship between early eukaryotic cells and bacteria.
Which is the longest mRNA?
The longest mRNA in humans is thought to be the mRNA for titin, a protein found in muscle cells. Titin mRNA has over 100,000 nucleotides and is responsible for producing the enormous titin protein that helps muscles function properly.
What is putative gene?
a putative gene is a piece of DNA thought to be a gene based on sequence (ex. Open Reading Frame) but either the protein produced or the function of what is thought to be the expressed protein is not known
Where did the word protein originate from?
The word was coined by a French Chemist in 1838 and comes from a Greek word 'Proteios' meaning the 'first quality' a substance thought to be essential to life by the Greeks. The modern use is from German 'Protein'. This word passed to the rest of the world from Germany via England in 1907
How do the structure of nucleic acids relate to their functions of information storage and protein synthesis?
The structure of nucleic acids, such as DNA, is composed of nucleotides arranged in a specific sequence. This sequence encodes genetic information that dictates the synthesis of proteins. During protein synthesis, the DNA sequence is transcribed into mRNA, which is then translated into a specific sequence of amino acids, resulting in the production of proteins. The specific arrangement of nucleotides in the nucleic acid molecule is crucial for the accurate transmission and interpretation of genetic information for protein synthesis.
What are the most primitive organisms today are thought to have a structure that is too simple to be considered cells.?
Viruses are considered the most primitive organisms that lack the complexity to be considered cells. They consist of genetic material (DNA or RNA) enclosed in a protein coat and are unable to carry out metabolic processes on their own.
Is RNA a thought to be the oldest and most primitive coding mechanism for life?
Yes it is the oldest and most primitive coding mechanism
What is necessary for replication of a prion?
For replication of a prion, there must be a misfolded form of the normal cellular prion protein (PrPc) present. This misfolded prion protein (PrPsc) acts as a template to convert normal PrPc into the abnormal form. The process of conversion is thought to involve a seeding mechanism where the misfolded protein induces other proteins to misfold.
Is endoplasmic reticulum the assembly line?
Yes, the endoplasmic reticulum (ER) can be thought of as an assembly line within the cell. It is involved in the synthesis, folding, and transport of proteins and lipids, acting as a site for cellular processes like protein modification and packaging. The rough ER, with ribosomes attached, is where protein synthesis occurs, while the smooth ER is involved in lipid metabolism and detoxification.
What may be thought of as post-Freudian ideas?
Dreams are thought of as "road maps" to the unconscious. Humans are thought to be motivated by strong, primitive drives.
What may be thought of as post freudian ideas?
Dreams are thought of as "road maps" to the unconscious. Humans are thought to be motivated by strong, primitive drives.
What group can be thought of as one of the words of the genetic message?
Codon combinations can be thought of as one word in the genetic message. Codons are the three-letter sequences of mRNA that correspond to a specific amino acid or a start or stop signal in protein synthesis. Multiple codons are strung together to code for the sequence of amino acids that make up a protein.
How much does it cost to fix a template screen?
about 100 thought 200 pluse tax
Stonehenge is thought to be a primitive what?
Some scientists believe that Stonehenge is thought to be a primitive form of observatory. It could have been used to show the relationship between the stars and the planets. Others believe that it was warning to others not to come to that part of the island.
Many scientists think genetic material was composed of protein because?
Protein was originally thought to be the genetic material because of its complexity, protein is made up 20 different amino acids while DNA only consists of four bases. This was logical as the complexity would account for diversity in organisms. But after more research was done it was realized that DNA was actually the genetic material.
What are some sentences with the word synthesis in it?
Her writing was a beautiful synthesis of complex thought and emotion. The students had to write a synthesis for their final project. According to the microscope slide, the cells were undergoing synthesis. Synthesis of the two chemicals in the unmarked beakers led to an explosion.
