What does queue mean in cell biology?
In cell biology what does the word queue describe? .. the long arm of a chromosome.
Which is defined as a cell structure made of DNA that gives all of the master instructions for the cell centromere chromosome allele gene?
chromosome. a structure made of DNA that gives the master instructions for a cell.
What do chromosomes contain?
DNA molecule In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
What is the function of a chromosome?
Chromosomes are thread-like structures in which DNA is tightly packaged within the nucleus. DNA is coiled around proteins called histones, which provide the structural support. Chromosomes help ensure that DNA is replicated and distributed appropriately during cell division.
Which best describes a gene?
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.
What do homologous chromosomes carry?
same genes The two chromosomes in a homologous pair are very similar to one another and have the same size and shape. Most importantly, they carry the same type of genetic information: that is, they have the same genes in the same locations.
Which is the find as a cell structure made of DNA that gives all of the master instructions for the cell?
which is defined as a cell structure made of DNA that gives all of the master instructions for the cell? chromosome.
How is DNA arranged within a chromosome?
Figure 1: Chromosomes are composed of DNA tightly-wound around histones. Chromosomal DNA is packaged inside microscopic nuclei with the help of histones. These are positively-charged proteins that strongly adhere to negatively-charged DNA and form complexes called nucleosomes.
Can you change your DNA from male to female?
Genetics overall cannot be changed (so far, at least) Sex chromosomes, in particular, determine whether someone will have female or male body parts. As you can see in the image below, these are chromosomes found in a typical person. We each have 23 pairs. The last pair are known as the sex chromosomes.
What is the difference between a gene and an allele quizlet?
A gene is a specific section of a chromosome where the base pairs that code for the characteristic are stored whereas an allele is the actual sequence of the base pairs in the section.
Which description best describes the function of chromosomes?
which of the following best describes the function of chromosomes? enable more efficient packing and transporting of genetic material in mitosis.
What are chromosomes in biology?
(KROH-muh-some) A structure found inside the nucleus of a cell. A chromosome is made up of proteins and DNA organized into genes. Each cell normally contains 23 pairs of chromosomes.
Which describes a gene quizlet?
Which best describes a gene? A segment of DNA that codes for a trait.
What best describes an allele?
The choice that best describes an allele is different forms of the same gene.
Why is the word homologous used to describe chromosome pairs?
The two chromosomes in a homologous pair are very similar to one another and have the same size and shape. Most importantly, they carry the same type of genetic information: that is, they have the same genes in the same locations.
How many homozygous alleles are there in these homologous chromosomes?
Homozygous (and its less common form homozygotic) means “relating to a cell that has two identical alleles for a particular gene at corresponding positions on homologous chromosomes.”
What is all your DNA together called?
Put three billion of these base pairs together in the right order, and you have a complete set of human DNA—the human genome.
Which of the following best describes a characteristic of DNA DNA that makes it useful as hereditary material?
Which of the following best describes a characteristic of DNADNA that makes it useful as hereditary material? There are many different types of nucleotide bases that can be incorporated into DNADNA. The nucleotide bases can also be used to provide the energy needed for reproduction.
Which are replicated during interphase Brainly?
Also, during interphase and before cell division, the DNA is replicated and the chromosomes are duplicated.
How does interphase prepare A cell to divide?
The interphase is the period of the cell cycle which prepares the cell to divide by providing the space for the nucleus and organelles. Space is provided by enlarging the cell. Hence, the cell is capable of functioning and dividing later by its own.
How many sexes are there?
two sexes Based on the sole criterion of production of reproductive cells, there are two and only two sexes: the female sex, capable of producing large gametes (ovules), and the male sex, which produces small gametes (spermatozoa).
How many genders are there?
There are many different gender identities, including male, female, transgender, gender neutral, non-binary, agender, pangender, genderqueer, two-spirit, third gender, and all, none or a combination of these.
What is the difference between a dominant allele and a recessive allele quizlet?
*What is the difference between a dominant and recessive allele? A dominant allele is always expressed or seen. it is in a homozygous (BB) or heterozygous (Bb) pair. A recessive allele is only expressed when in a homozygous pair(bb).
What is the difference between genotype and phenotype quizlet?
What is the difference between genotype and phenotype? The phenotype is an organism's physical appearance, and the genotype is the genetic makeup.
What is the best description of the structure of a chromosome in the nucleus of a non dividing cell?
What is the best description of the structure of a chromosome in the nucleus of a non-dividing cell? One long DNA molecule, associated with many proteins.
What is DNA in biology?
The molecule inside cells that contains the genetic information responsible for the development and function of an organism. DNA molecules allow this information to be passed from one generation to the next.
What below best describes a gene?
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However many genes do not code for proteins.
What phrase best describes a gene?
Which phrase best describes a gene? a segment of a DNA molecule that contains the instructions for producing a trait in an organism. genes in an egg cell.
Which describes a gene?
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.
What is an allele quizlet?
Allele. one of two alternate forms of a gene that can have the same locus on homologous chromosomes and are responsible for alternative traits.
