Is the structure that is found in the nucleus and where genes are located

Chromosomes are composed of

These are the structure of chromosome which contains the dna which packages the nuclear genetic material of the cell

They play crucial role for the accurate distribution of genetic information to the daughter cells.

How many sister chromatids contains in one chromosome

This contains the tightly called double helix structure of dna

Chromosomes are joined together by which allow proper separation during mitosis and meiosis

How many pairs of chromosomes in somatic cells do human have

These are non sex chromosomes that carries genetic information related to the body traits and function

This chromosomes determines the biological sex

What is the chromosome for female

What is the chromosome for males

How many pairs of non sex chromosomes do human have

How many pairs of sex chromosomes do human have

What phase do centromere is visible at

A constriction visible on metaphase chromosomes where two sister chromatids are joined together. It is essential to the survival of the chromosome during cell division.

Chromosome is the site where interaction with the____during cell division

This ensures chromosome stability and proper cell segregation during cell division

Serves as the attachment site for kinetochore

A protein context which that allows the attachment and alignment of the mitotic spindle fibers

This is the functional elements microtubules that separate the sister chromatids during cell division

This attach to chromosomes to the spinal fibers during cell division

What are the different classifications of centromere based on its position

Classification of centromere which the centrome is located in the middle ensures that chromosomes from the p and q arm are equally divided

Classification of centrome which centromere is position is between near one end of the q arm

Classification of centromere which found at the end or slightly of the center between middle and end resulting to one arm longer

It is the physical end of chromosomes which acts as protective cups of chromosome ends and it prevents end to end fusion of chromosomes

This prevents dna degradation resulting after chromosome breakage and it plays a role in synapsis during meiosis

This is a result of dna degradation or chromosome breakage due to collision

This refers to the production of similar genes of offspring from the parent cell

This refers to the pairing of homologous chromosome

Operates at the end of the chromosome this is an enzyme consisting of a protein and an rna component which the rna serves as a template for synthesizing telomere dna

It is an specific chromosomal region found in the satellite stalks of human acrocentric chromosome

What chromosomes do acrocentric chromosome of nuclear organizing region found

It is responsible for the formation of nucleoli during interphase cell cycle also serves as the site of rrna genes and its production

What is the general role of ribosome

How many chromosomes are are found in one copy of acrocentric chromose of humans

How many nor human chromosome have

What are the two types of chromatin

Type of chromatin which is loosely organized extended and uncoiled which is applicable for transcription. It contains active early replicating genes for gene expression during S phase of cell cycle

This refers to dna forming rna to protein

Type of chromatin which is highly contracted genetically inactive and late replicating during the space of mitosis which is does not participate in gene expression

What are the two types of heterochromatin

The type of a heterochromatin is able to switch to active to inactive chromatin depending on the cell type and development

Inactivated x chromosome of female cells are also known as

Condensation of facultative heterochromatin occurs during

Replication of faculty petrochromatin occurs during the late what stage of the cell cycle

Type of Heterochromatin which is the condensed inactivated x chromosome of female cells in which one x chromosome of every female cell is randomly inactivated

Type of heterochromatin which consists of simple repeats of nitrogenous bases responsible for the regulation of crossing over the exchange of genes from one sister chromatid to the other during cell division

Constitutive heterochromatin are commonly found on

A ordered set of events resulting in cell growth and division into two daughter cells

What are the two alternating processes of the cell cycle

A process of cell cycle which is the doubling of its genome which doubles DNA

Process of cell cycle which halving of the genome

This refers to cytoplasmic division

What are the stages of the cell cycle

Stage of cell cycle which is the growth and preparation of the chromosomes for replication in which the cell also experiences growth and prepares for dna replication. This also produce rna and proteins

This is the stage when the dna replication occurs and the duplication of the centrosome

Stage of cell cycle which is the final preparation of mitosis

This is the stage of cell cycle which the nuclear division or the chromosome separates in identical sets and the cytoplasmic division which is the cytokinesis occurs

What are the different stages of mitosis

This occurs during cytokinesis

Ensures correct progression before leading to phases of cell cycle

Cell regulator which levels remain fairly stable but each must bind with the appropriate cycling in order to be activated

Group is added to a variety of protein substrate that control processes into the cell cycle

Cell cycle regulator which controls the g1 to s phase and also prepare dna replication

Cell cycle regulator which regulates s phase and ensures dna duplication

Cell cycle regulator ensures that there is accurate separation of chromosomes in the cell division

Regulatory proteins that find to cdk which levels rise and fall with the stages of cell cycle

G1 cyclins activates what CdK in preparation of DNA replication

Also known as D cyclin

Also known as S phase cyclin

Also known as Mitotic cyclin

It is also known as cyclosome which destroys Cohesin allowing sister chromatids to separate and degrades mitotic cyclins

This holds sister chromatid destroyed by the APC/C

Tumor suppressor protein which functions to block the cell cycle if the dna is damaged and it can also lead to apoptosis when the dna damage is severe.

Mutation of this cell cycle regulator is the most frequent mutation leading to cancer

This refers to the condition where the extreme case of p53 mutation leads to high frequency of cancer in affected individuals

A disease that results when the regulation of the cell cycle is not controlled and normal cell growth and behavior is lost

A cell cycle inhibitor which blocks the entry in the space by binding to cyclins and CdK

Reduce levels of this regulatory protein for outcome for breast cancer patients
