I will answer this by example: BCD is unweighted code, XS3 is weighted by 3 code.

0 in BCD 0000, XS3 0011

1 in BCD 0001, XS3 0100

2 in BCD 0010, XS3 0101

3 in BCD 0011, XS3 0110

4 in BCD 0100, XS3 0111

5 in BCD 0101, XS3 1000

6 in BCD 0110, XS3 1001

7 in BCD 0111, XS3 1010

8 in BCD 1000, XS3 1011

9 in BCD 1001, XS3 1100

Addition in recombinant DNA means to remove non coding or non functional DNA and inserting the functional or coding seuence.


weighted codes are the codes which having the specific weight asign to the each number position, non-weighted codes are the codes which having the no weight


weighted code-8421 (BCD) binary, hex, octal ETC. non-weighted code-grey codes, excess-3 etc.


The non-coding sections of a gene are known as introns. The coding sections of a gene are known as exons.


The result you get from reading the gel from the bottom up is called the anti-coding (or non-coding strand).


Coding DNA or exons are varying among individuals. But non-coding DNA doesn't vary among individuals and they don't carry information about gene expression patterns. Therefore, non-coding DNA is used in forensic analyses.


First of all a gene by definition codes for something so there is no such thing as a "non coding gene". To your question non-coding DNA is no more prone to mutation. A mutation in a non-coding region is far more likely to passed onto offspring because a mutation has no effect on the organism that gets it. A mutation in a gene is more likely to be bad thing than beneficial. So over time (many generations) there are more differences in non coding regions of DNA between individuals. This why DNA fingerprinting looks at differences in non coding regions between people to find unique profiles.


DNA fingerprinting identifies and replicates the non-coding gene sequences.


An intron is a non-coding section of a gene. This is spliced out before the creation of the final mRNA.


Junk DNA is non-coding DNA it does not code for protein.


Coding in accounts payable nothing but an invoice number which will be generated automatically towards customer transation or a payment.


There is not a direct relationship. The reason is, much of the DNA in organisms is non-coding, that is, does not contain genes. Non-coding DNA can be duplicated or lost (as can coding DNA), so in theory, a less complex organism can, through duplications of its non-coding DNA, generate a larger overall genome than a more complex organism.


they are non-coding mRNA sequence in a mRNA strand but are not found in DNA as they are removed during mRNA processing before the formation of protein


Coding is another name for programming. To get a computer to do what you want, it has to be told what to do. Programs tell it what to do, and it takes programmers (coders) to write the programs.


LIght Weight Programming means the coding should be small .


"Coding segments" is the term given to genes, segments of the DNA strand that code for a protein. Much of an organism's genome is non-coding segments, portions that do not have a role in protein synthesis.


DNA is a double helix. So during replication it unwinds and separates into two strands. One strand will be called the non-coding and the other will be called the coding strand. The non-coding strand will be the template for the new one.


Coding in the medical field is assigning a specific code for each procedure to ensure that patients are charged accordingly. Coding in a business sense is assigning a specific code for each operation of the business to allocate costs and income. For example, sales might use an "S" for coding.


An intron is the non-coding region of a gene cut out by enzymes. An exon is the coding regions of a gene then spliced together with introns.


Introns are non coding part ....that will be remove during splicing.


The top strand, which is drawn 5' to 3' and which contains the promoter sequences in the conventionally written orientation (such as the TATA box) and which has the same sequence as the new RNA (except for U instead of T) is the plus strand or the sense strand or the non template strand or the coding strand. The bottom 3' to 5' strand is the minus, or template, or antisense strand. Your sequence therefore is the coding strand, but the RNA is transcribed off of the non-coding, template, or antisense strand.


According to me,when this strand is transcribed the mRNA formed is not coding for any mino acid that is why this portion of gene is removed from DNA.


The genome is the totality of all genetic material, both coding sequences (genes) and non-coding sequences, in an individual organism.


what is weighted codes: The decimal value of a code is obtained summing up the positional values. weghted binary code s are those which obey positional weighting principle. each position of number represents a specific weight. There are millions of weighted code The most common one is 8421 Non weighted codes: This codes are not positionaly weghted. each position with in the binary no is not assgned to afixed value.Examples of nonweghted code is ASCCI, GREY CODE, EBCDIC CODE etc


genes are the segments of dna. dna is the whole genome and it contains coding sequences as well as non-coding sequences and the coding sequences are the genes. A gene codes for a protein. A full single gene can be present at one place on dna, or fragments or parts of a single gene may be present at different locations on dna with non-coding region in between.
