Which cell structure are known as director of cell and little neculeous respectively?
The cell structure known as the "director of the cell" is the nucleus, as it houses the cell's genetic material and regulates various cellular activities. The term "little nucleolus" refers to the nucleolus, which is a dense region within the nucleus responsible for ribosome production. Together, these structures play crucial roles in maintaining cellular function and protein synthesis.
What organelle of a cell is responsible for synthesis of new molecules?
The organelle responsible for the synthesis of new molecules in a cell is the ribosome. Ribosomes are the sites of protein synthesis, where they translate messenger RNA (mRNA) into polypeptide chains, which then fold into functional proteins. Additionally, the endoplasmic reticulum (specifically the rough ER) is involved in the synthesis and processing of proteins, while the smooth ER is responsible for lipid synthesis. Together, these organelles play key roles in the production of various biomolecules.
What is a attached ribosome?
An attached ribosome is a ribosome that is bound to the endoplasmic reticulum (ER) membrane. It is involved in the synthesis of proteins that are either secreted by the cell or inserted into the membrane. These proteins play crucial roles in various cellular functions.
Enzymes are produced as a direct result of which process?
1)protein synthesis 2)photosynthesis 3)respiration 4)enzymatic hydrolysis
What play many key roles in the manufacture of proteins?
Ribosomes are a crucial component in the manufacture of proteins, as they are responsible for translating the genetic code from mRNA into a specific sequence of amino acids. Transfer RNA molecules also play a key role by bringing the correct amino acids to the ribosome during protein synthesis. Additionally, enzymes and various factors are involved in the regulation and coordination of protein synthesis within a cell.
What is the one job in whack most RNA molecules are involved?
RNA molecules are most involved in protein synthesis, specifically in the process of translation where messenger RNA (mRNA) is decoded by ribosomes to produce proteins. RNA molecules such as transfer RNA (tRNA) and ribosomal RNA (rRNA) play key roles in this process by carrying amino acids and forming the ribosome structure, respectively.
What are the differences between methionine and cysteine in terms of their roles in protein synthesis and cellular functions?
Methionine and cysteine are both amino acids that play important roles in protein synthesis and cellular functions. Methionine is essential for initiating protein synthesis, while cysteine is important for forming disulfide bonds that help stabilize protein structures. Methionine is also involved in the methylation of DNA and RNA, while cysteine is important for antioxidant defense and detoxification processes in cells. Overall, methionine and cysteine have distinct roles in protein synthesis and cellular functions, with methionine being more involved in the early stages of protein synthesis and cysteine playing a key role in protein structure and cellular defense mechanisms.
What is the relationship between glycine and alanine in terms of their roles in protein synthesis?
Glycine and alanine are both amino acids that play important roles in protein synthesis. Glycine is the simplest amino acid and is often used as a building block in the structure of proteins. Alanine, on the other hand, is a non-essential amino acid that can be synthesized by the body. Both glycine and alanine are involved in the process of protein synthesis, where they are incorporated into the growing protein chain according to the genetic code provided by DNA.
Which cell structure are known as director of cell and little neculeous respectively?
The cell structure known as the "director of the cell" is the nucleus, as it houses the cell's genetic material and regulates various cellular activities. The term "little nucleolus" refers to the nucleolus, which is a dense region within the nucleus responsible for ribosome production. Together, these structures play crucial roles in maintaining cellular function and protein synthesis.
What is the function of the nucleulous?
The nucleolus is a prominent substructure within the nucleus of eukaryotic cells, primarily responsible for the synthesis and assembly of ribosomal RNA (rRNA) and the formation of ribosome subunits. It serves as the site where rRNA is transcribed, processed, and combined with ribosomal proteins imported from the cytoplasm. This process is crucial for ribosome production, which is essential for protein synthesis in the cell. Additionally, the nucleolus plays roles in cellular stress responses and regulation of the cell cycle.
What are the roles of two organelles?
The mitochondria carry out aerobic cellular respiration, and ribosomes carry out protein synthesis.
What is a attached ribosome?
An attached ribosome is a ribosome that is bound to the endoplasmic reticulum (ER) membrane. It is involved in the synthesis of proteins that are either secreted by the cell or inserted into the membrane. These proteins play crucial roles in various cellular functions.
How many loops and stems does trna has?
tRNA (transfer RNA) is composed of one loop and three stems. The loops and stems play important roles in tRNA's ability to bind to specific amino acids and the ribosome during protein synthesis.
Enzymes are produced as a direct result of which process?
1)protein synthesis 2)photosynthesis 3)respiration 4)enzymatic hydrolysis
The substance being synthesized in the cell is most likely a?
protein, as proteins are the most abundant macromolecules synthesized in cells and play a variety of essential roles in cell structure and function. Proteins are synthesized through a process called protein synthesis, which involves transcription of DNA to mRNA and translation of mRNA to protein at ribosomes.
What play many key roles in the manufacture of proteins?
Ribosomes are a crucial component in the manufacture of proteins, as they are responsible for translating the genetic code from mRNA into a specific sequence of amino acids. Transfer RNA molecules also play a key role by bringing the correct amino acids to the ribosome during protein synthesis. Additionally, enzymes and various factors are involved in the regulation and coordination of protein synthesis within a cell.
What percent of DNA codes for protein synthesis?
Approximately 1-2% of the human genome codes for protein synthesis. The rest of the DNA is involved in regulating gene expression, controlling cell functions, and having other structural roles.
