L22: string builder | lesson 22 | dsa in java | java. This video is a part of the new playlist of videos on data structures and algorithm in java by coding ninjas The link of the playlist is given in the description below. if you have not yet watched the previous videos go ahead and click the earlier videos and watch them String bundle class and string buffer class are having very much same working only the point is the operations or the methods that are implemented in the core level. In string buffer classes are following synchronized methods. in the stream builder class. So if you are if you have in mind to add more than 16 character like 17 18. The new size will become from 16 to 30 16 into 232 plus 234 initial capacity of the string is.

Overview:

In this activity you will transcribe a sequence of DNA into RNA and translate this sequence into the amino acids that form a protein. You will go through the process of Protein Synthesis to determine what protein is being made. The sequence is given below along with instructions for the assignment and some short discussion questions.

Background Information:

DNA is the genetic material in the nucleus of cells and contains the instructions for all of the processes of your body. DNA is double stranded and made of nucleotides that contain one of four bases: adenine, thymine, guanine, or cytosine. DNA is very important and therefore does. not leave the nucleus. This is why mRNA is created.

Transcription - the process of copying a segment of DNA into RNA

RNA is transcribed from DNA in short segments so that it can leave the nucleus. This short, segment that is copied from DNA uses the same complementary nucleotides as DNA but in place of thymine it codes a nucleotide called uracil. The RNA goes through some cutting and splicing before leaving the nucleus as mRNA. The strand of mRNA now has only the coding portions spliced together.

Translation - the process of coding mRNA into amino acids that create a protein

The mRNA leaves the nucleus into the cytoplasm and floats around until it connects with a ribosome. The ribosome attaches to the 5-prime end of the mRNA. The ribosome reads the mRNA in sets of 3 nucleotides called a codon. Each codon corresponds to an amino acid. As the ribosome reads a codon, tRNAs bring in the corresponding amino acid. The ribosome then attaches the amino acids in a chain as it reads the mRNA and creates a string of amino acids called a protein. There are specific codons to signal start and stop that say when a protein is complete.

Assignment:

You will transcribe a strand of DNA into RNA and then translate this RNA sequence into amino acids that form a protein. Your submission will be of the original DNA strand, the transcribed RNA, and the actual protein chain of amino acids.

2. Using the RNA strand that you transcribed, compare each codon to the chart above and translate that into the correct amino acids to create a protein. (You may write the) amino acid name or abbreviation, but do not use the letter.) What would the amino acid chain be that creates the protein?

Discussion Questions:

1. What is the purpose of mRNA?

2. Why is only part of the mRNA sequence translated into amino acids?

3. Where in the cell is DNA transcribed into mRNA?

4. What nucleotide is used only in RNA to replace a certain nucleotide in DNA?

5. Where in the cell is mRNA translated into amino acids to form a protein?

Today’s a good dayknow it’s finna be sweetI’m listening to Dom on Kennedy streetremembering the west coast where the energy’s sweetI did my yoga this morning so my memory’s peakedbut anyway, off-grid sh*t, nothing to tweetthe city’s still filling up with those who dance off-beatmore than 140 characters, and all of them weakthey walk by, low eye, act like they can’t speakthey walk dogs—when I say that I don’t mean their feetthat’s cause they scared of their neighbors, them they don’t wanna meetbut anyway, this is third generation for memy parents and my grandparents all from DCso I feel like I notice things other folks can’t seeAnd like I represent things other folks can’t beand I rememberall Black on the green lineand all the kids had jobs in the summertimesay what you want about Barry, but he cared for the poorand that ain’t who these new fools working forI tell em, “That aint who these new fools workin for”they tryna kick us all out and just build more storesbut anyway...[HOOK]But Anyway I could go on foreverbout all of the bullthat I’m tryna make betteror even about me and the twenty first letterI feel like I know youeven though we ain’t togetherlive foreverok, you etting moneywell I’m etting peace of mind that you can’t take from meso I feel I’m doing fine and as long as I love meI follow my own signs and the world can’t judge mepretty or ugly.

VERSE 2speed cameras send me pictures in the mailI hate this city sometimes, but oh well...what can I do? Pay the damned ticketthink it’s unconstitutional but I don’t picketthere’s other battles, other cages to rattlethey still lockin us up and tryna herd us like cattleI talk about it cuz nobody else tattlesthey takin juveniles to Iowa, sayin that’llteach embut it won’t.I swear on everything this system is a joke, not rehabilitationand it’s not about hopeit’s about the corporations,ten dollar soapand ten dollars for ten minutes on the phone till you brokewhere they recording every single word that you spokethey probably ignoring every single word that I wrotecu if I ain’t burn it down I was only blowin smoke.[HOOK Repeats]And anyway, I’m just speaking from my hearteven though the industry is tryna keep us aparteven though my enemies be steadily throwing dartsI’mma make it to the end, man I said it from the startso play your partand your positionpen and paper’s like the pots when I’m cookin in the kitchenif I serve it up hot, know the people gon listengon give it all I got, I’m the link that was missingno more wishingcause I’m herevibratin off lovenot the frequency of fearI’mma keep it right there and watch the hate disappeareveryday is my yearget that sh*t clear.
