What is the designation for the short arm of a chromosome?
Chromosome # + pso the short arm of Chromosome 11 is referred to as 11p
What various types of genetic material in order from simplest to most complex?
nucleus → chromosome → gene
Is the smallest gene cell chromosome?
Chromosome 21 is the smallest human chromosome. Inside of the chromosome, there are 48 billion nucleotides, the building blocks of DNA.
What chromosomes can be affected by changes in chromosome numbers?
Any chromosome can be affected by changes in chromosome numbers. This can include trisomy (three copies of a chromosome), monosomy (one copy of a chromosome), or other abnormalities such as deletions or duplications. These changes can lead to genetic disorders or abnormalities.
What is a sat chromosome?
A sat chromosome, short for satellite chromosome, is a chromosome with a secondary constriction that contains highly repetitive DNA sequences called satellite DNA. These regions appear as small, secondary appendages on the chromosome and play a role in chromosome structure and organization.
Is an x chromosome and chromosome the same thing?
An x chromosome is specifically a feminine chromosome. With a x and y chromosome its male, with a x and x, it is a female.
Which chromosome contains the sex gene?
chromosome 1 chromosome 1
What are the name of 23 chromosomes in human body?
No, there are 46 chromosomes in one cell. A gamete, or sex cell, has 23 chromosomes because during fertilization, the female and male gametes (egg and sperm, respectively) come together to form a new cell with 46 chromosomes
What is the designation for the short arm of a chromosome?
Chromosome # + pso the short arm of Chromosome 11 is referred to as 11p
Does an x chromosome looks the same as a y chromosome?
No. An 'X' chromosome looks like an 'X'. The 'Y' chromosome looks like a deformed 'X'. It is noticeably different to an 'X' chromosome. Also, the 'Y' chromosome is only a third of the size of an 'X' chromosome - an 'X' chromosome is 155 million base pares, while the 'Y' chromosome is only 58 million base pairs.
Why do some traits occur mainly in males even though they can be inherited only from their mothers?
Consider recessive traits on the X chromosome. Women have two of these, so it is statistically less likely that a woman would express this recessive trait and much more likely that it would be masked by a dominate X chromosome. If a male gets a recessive X from his mother ( remember, males have one X and one Y chromosome ) it is going to be expressed as there is no corresponding chromosome to mask it.
Why do traits that are controlled by genes on the same chromosome not always appear in the expected ratio in offspring?
I think this has something to do with "crossing over," but I do not remember the details. All I remember is that the allelle of one chromosome may overlap and switch with the allelle of another chromosome, which results in unexpected ratios of the genotypes and phenotypes of traits represented by genes that would normally be found on the same chromosome.
4 chromosome mutations?
Deletion: Part of a chromosome is missing. Duplication: A segment of a chromosome is copied multiple times. Inversion: A segment of a chromosome is reversed in orientation. Translocation: Part of a chromosome breaks off and attaches to another chromosome.
What is the difference between Edward's syndrome and Patau's syndrome?
in Patau there is an extra chromosome in chromosome 13, in Edwars it the extra chromosome is in chromosome 18
What condition is carried on a chromosome other then the sex chromosome?
The gene that causes cystic fibrosis is located on chromosome 7, which is an autosome, not a sex chromosome.
What is the purpose of nucleaus?
A nucleaus is DNA or more definitively a chromosome unbundled. Remember that they only coagulate during Mitosis or Meiosis. The nucleaus also controls the cell
List these in order from smallest to largest chromosome gene cell?
Smallest to largest: Gene (a place on a chromosome); chromosome (there are 46 in human cells); and DNA (because it accounts for all the genetic material in a cell).
