Function: to make up genes-holds instructions to make proteins (including enzymes that promote chemical reactions)功能:把携带遗传信息的基因组成蛋白质(包括参加化学反应的消化酶)Facts about RNA 关于RNA的要素 Shape: single helix and other shapes (many shapes)形状:单螺旋和其它形状(多种形状)...
DNA holds the instructions for creating living things. The double helix structure of DNA was described in 1953. In 2003, the Human Genome Project recorded the first sequence of the complete set of DNA in a human. National DNA Day, celebrated on April 25 each year, commemorates the successful...
Supplies instructions for cell processes, like how to make proteins 2. Can be copied each time a cell divides 3. It is. Y Stock NUCLEIC ACIDS DNA DNADNA is a nucleic acid. Within the nucleus chromosomes are made of DNA. DNA contains instructions controlling protein synthesis. DNA Structure ...
DNA is a fascinating topic that holds the key to understanding our biological makeup. It's like a secret code that unlocks the mysteries of life. When we talk about DNA, we're actually referring to the genetic instructions that are passed down from generation to generation. It's like a ...
start along the strand. The enzyme RNA polymerase arrives at this location and becomes part of a promoter complex. All of this is to ensure that mRNA synthesis begins exactly where it is supposed to on the DNA molecule, and this generates an RNA strand that holds the desired coded message....

As a cell prepares to build a new protein, its DNA unzips to expose one strand of the gene with the instructions to build said protein. Then, an enzyme zooms in and constructs a new RNA molecule whose sequence mirrors that of the unzipped gene. This RNA copy, called messenger RNA (mRNA...
The Y chromosome, shown in blue above, is passed from father to son without mixing with the DNA of the mother, so it is in essence tracked intact for generations – with the exception of occasional mutations. Two kinds of mutations make Y DNA genealogically useful. They are STRs, short ...
What can be said about the 3 things outlined in the diagram to the right? It is a nucleotide made up of a sugar, phosphate, and a nitrogeneous base. Which molecule carries out the instructions coded in DNA? mRNA Part of DNA is copied in a process called what? transcription ...
You may or may not provide more direct or additional instructions. You can even just google. I asked DALL-E to “create a picture by interpreting the phrase, ‘when life gives you scraps, make beautiful quilts’.” Next, I included a photo of myself as a young person and asked Chat...
