How is information for a specific protein carried on the DNA molecule?
Each protein is coded for by a specific section of DNA called a gene. Together, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene’s DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.
What is the role of mRNA in expressing specialized structures?
Messenger RNA (mRNA) is the molecule that links genes to proteins. Efficient and smooth interactions of the molecules of life allow us humans to function well. This process is called gene expression. As humans and their cells age body protein synthesis change with changes occurring in their metabolism.
Which of the following best describes a gene?
Correct Option – (B) A specific length of DNA responsible for the inheritance and expression of the character. Gene is a particular segment of DNA which is responsible for the inheritance and expression of a particular character.
Where are DNA units stored?
Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). Mitochondria are structures within cells that convert the energy from food into a form that cells can use.
How is information for a certain protein carried on the DNA Quizizz?
How is information for a specific protein carried on the DNA molecule? The order of nitrogenous bases determines the order of amino acids in the proteins synthesized. The amount of thymine and guanine in the DNA molecules determines the length of the genes.
Do humans have RNA?
Yes, human cells contain RNA. They are the genetic messenger along with DNA. The three main types of RNAs are: Messenger RNA (mRNA) – it transfers the genetic information present in DNA to proteins.
What is nuclear tide?
nu·cle·o·tide Any of a group of compounds consisting of a nucleoside combined with a phosphate group and constituting the units that make up DNA and RNA molecules.
What happens to mRNA in the body?
How long mRNA lasts in the body. The Pfizer and Moderna vaccines work by introducing mRNA (messenger RNA) into your muscle cells. The cells make copies of the spike protein and the mRNA is quickly degraded (within a few days). The cell breaks the mRNA up into small harmless pieces.
Where is mRNA found in the cell?
nucleus
The process of making mRNA from DNA is called transcription, and it occurs in the nucleus. The mRNA directs the synthesis of proteins, which occurs in the cytoplasm. mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes.
