The p arm is the shorter arm of the chromosome. The q arm is the longer arm. For chromosomes which are metacentric, the arms tend to be the same length. For submetacentric, acrocentric, or telocentric, the p and q arms show clear differences in length- and thus are classified accordingly.

The two chromatid arms on a chromosome are what?

The two chromatid arms on a chromosome are identical copies.


When DNA is copied to form chromosomes that have 2 sister chromatids this is called DNA .?

Each chromosome has two arms, labeled p (the shorter of the two) and q (the longer). The p arm is named for "petite" meaning 'small'; the q arm is named q simply because it follows p in the alphabet. (According to the NCBI, "q" refers to the French word "queue".) They can be Metacentric A chromosome is metacentric if its two arms are roughly equal in length. In some cases, a metacentric chromosome is formed by balanced Robertsonian translocation: the fusion of two acrocentric chromosomes to form one metacentric chromosome. Submetacentric If arms' lengths are unequal, the chromosome is said to be submetacentric Acrocentric If the p (short) arm is so short that is hard to observe, but still present, then the chromosome is acrocentric (The "acro-" in acrocentric refers to the Greek word for "peak."). In an acrocentric chromosome the p arm contains genetic material including repeated sequences such as nucleolar organizing regions, and can be translocated without significant harm, as in a balanced Robertsonian translocation. The domestic horse genome includes one metacentric chromosome that is homologous to two acrocentric chromosomes in the conspecific but undomesticated Przewalski's horse. This may reflect either fixation of a balanced Robertsonian translocation in domestic horses or, conversely, fixation of the fission of one metacentric chromosome into two acrocentric chromosomes in Przewalski's horses. A similar situation exists between the human and great ape genomes; in this case, because more species are extant, it is apparent that the evolutionary sequence is a reduction of two acrocentric chromosomes in the great apes to one metacentric chromosome in humans Telocentric A telocentric chromosome's centromere is located at the terminal end of the chromosome. Telomeres may extend from both ends of the chromosome. For example, all mouse chromosomes are telocentric Holocentric With holocentric chromosomes, the entire length of the chromosome acts as the centromere. Examples of this type of centromere can be found scattered throughout the plant and animal kingdoms with the most well known example being in the worm, Caenorhabditis elegans.


What is a list of the 3 parts of a chromosome?

Telomere - The ends of the chromosome. Centromere - The primary constriction of the chromosome. Chromatid - A single molecule of DNA. The centromere also divides the chromosome into a short arm (p) and a long arm (q).


If p equals q then q equals p?

yes


What does the 24 in chromosome 8q24 mean?

8 is the chromosome number, q means the long arm of the chromosome, and the 24 is the position on the long arm. It's like coordinates to find the position on the chromosome.

What does the q in chromosome 8q24 mean?

The 'q' refers to the long arm of the chromosome. A prototypical condensed chromosome has two arms: a short arm and a long arm. The 'p' stands for the French word 'petit' (which means small). The 'q' doesn't stand for anything in particular, but because 'q' comes after 'p' in the alphabet, it is used to refer to the long arm of the chromosome.

If p q and q r then p r. Converse statement B.A syllogism C.Contrapositive statement D.Inverse statement?

Converse: If p r then p q and q rContrapositive: If not p r then not (p q and q r) = If not p r then not p q or not q r Inverse: If not p q and q r then not p r = If not p q or not q r then not p r


What is the sum or difference of p and q?

The sum of p and q means (p+q). The difference of p and q means (p-q).


What is the truth table for p arrow q?

If p = 50 of q then q is 2% of p.


What is the theory of kelvin's double bridge experiment?

Theory: - Kelvin's bridge is a modification of whetstone's bridge and always used in measurement of low resistance. It uses two sets of ratio arms and the four terminal resistances for the low resistance consider the ckt. As shown in fig. The first set of ratio P and Q. The second set of ratio arms are p and q is used to connected to galvanometer to a pt d at an Approx. potential between points m and n to eliminate the effects of connecting lead of resistance r between the known std. resistance 's' and unknown resistance R .The ratio P/Q is made equal to p/q. under balanced condition there is no current flowing through galvanometer which means voltage drop between a and b, Eab equal to the voltage drop between a and c, Eamd. Now Ead=P/P+Q ; Eab=I[R+S+[(p+q)r/p+q+r]] ------------(1) Eamd= I[R+ p/p+q[ (p+q)r/p+q+r]] ---------------------(2) For zero deflection->Eac=Ead [ P/P+Q]I[R+S+{(p+q)r/p+q+r}]=I[R+pr/p+q+r] ----(3) Now, if P/Q=p/q Then equation… (3) becomes R=P/Q=S ------------------------------------------------------(4) Equation (4) is the usual working equation. For the Kelvin's Double Bridge .It indicates the resistance of connecting lead r. It has no effect on measurement provided that the two sets of ratio arms have equal ratios. Equation (3) is useful however as it shows the error that is introduced in case the ratios are not exactly equal. It indicates that it is desirable to keep r as small as possible in order to minimize the error in case there is a diff. between the ratio P/Q and p/q. R=P/QS


How do you write the negation of if and then?

If p then q is represented as p -> q Negation of "if p then q" is represented as ~(p -> q)

Why does multiplication or division with a negative number yield a negative answer?

The assertion in the question is not always true. Multiplying (or dividing) 0 by a negative number does not yields 0, not a negative answer.Leaving that blunder aside, let p and q be positive numbers so that p*q is a positive number.Thenp*q + p*(-q) = p*[q + (-q)] = p*[q - q] = p*0 = 0that is p*q + p*(-q) = 0Thus p*(-q) is the additive opposite of p*q, and so, since p*q is positive, p*(-q) must be negative.A similar argument works for division.
