Chromatin and chromosome are the two types of condensed structures of the DNA molecules. follicle stimulating hormone receptor is FSHRwhat are the specific conventions as to how genes are written?1) when referring to a gene always italicise the letters but do not italicise its related protein the vehicle that ensures stable maintenance of the genetic info and facilitates its transmission to the next generation.
-Genetic material in a cell undergoing motosis/meosis (cell division)-We have 23 pairs of chromosomes 46 in total. The DNA molecules are condensed 50 times than its normal structure in the chromatin fibres. histone protein isa linear and highly compacted and organised DNA molecules with associated proteins which encodes genetic informationthe region of a chromosome which links sister chromatids.
Honor Code. follicle stimulating hormone receptor is FSHRwhat are the specific conventions as to how genes are written?1) when referring to a gene always italicise the letters but do not italicise its related protein Community Guidelines. It can result in one daughter cell with an extra chromosome (2n+1) and the other daughter cell missing one chromosome (2n-1) When chromosome nondisjunction occurs in somatic cells how is the … When chromatin is condensed and further organized, we have chromosomes . what is the name and structure of the basic unit of chromatinfunctions as a linker protein that creates the ring structure for the nucleosome chains thus stabilizing the chromatin fiber; it is THE ONLY HISTONE protein not at the nucleosome core, helps further condense the genetic materialwhat is the name of the 30nm coiled fibre like structure of nucleosome that makes up the chromosome?give 5 main differences between euchromatin and heterochromatin1) euchromatin stains lightly , hetero stains darkly what are the names of the 2 different types of heterochromatinwhat are the main features of constitutive heterochromatin?what are the main features of facultative heterochromatin1) areas of this gene sequence can differ between cell typeswhy are histone tails important to the structure of the solenoid fibre ?they are used in the packaging and folding of nucleosomes into chromatin into chromosomes by their R groups interacting with the R groups of the histone tails of other nucleosomes.
Mitotic Phase, sister chromatids are separated and a complete set of chromosomes is delivered to each pole of the cell. typically found in proteins that mediate transcriptional silencingmultisubunit enzyme complexes that use the energy provided by ATP hydrolysis to change the positions of nucleosomes on DNA.
important for meiosis and mitosis as its where the spindle can attach.repetitive DNA sequences at the end of the chromosome which which act to preserve the integritry of the chromosome and prevent loss of any DNA. Then recruits other proteins, including nucleosome remodeling complexes or other enzymes that act on DNAbind to specific methylated lysines.
Each chromosome (unreplicated form) consists of one chromatid. "Cap" the ends of the chromosome to prevent essential DNA reacting with molecules which could potentially cause cancerDNA sequences from which DNA replication is intitiated in the S phase of the cell cyclenumber of chromosomes in the nucleus of an organisms cell (its 46 for a human)length of DNA which can be transcribed and codes for a functional protein or functional RNAwhat is the function of a promoter region in a gene?DNA sequence at which the machinery for transcription is assembledfirst nucleotide in the gene sequence that is transcribed into RNA during transcriptionDNA which is transcribed but not included in the mature mRNADNA sequences that are transcribed and included in the mature mRNADNA sequences which indicate the point at which to end transcription1- names of genes that describe their function e.g.
What does chromosome nondisjunction do in somatic cells? Learn vocabulary, terms, and more with flashcards, games, and other study tools. They are then looped and condensed into what is known as the chromosome-Area where the chromatids of a chromosome are attached.-A specialized region on the centromere that links each sister chromatid to the mitotic spindle.-one of two identical "sister" parts of a duplicated chromosome the failure of homologous chromosomes or sister chromatids to separate as they normally do during cell division.
The chromosomes move until they form two groups near the poles of the spindle OR by definition Either of the two daughter strands of a replicated chromosome that are joined by a …
Chromosomes are structures within the nuclei of eukaryotic cells that contain DNA combined with proteins.
the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed. Start studying IGE-unit1- genes, chromatin, chromosomes.
Chromosome pairs of the same length, centromere position, and staining pattern that possess genes for the same characters at corresponding loci. Generates sites for the bonding of proteins containing domains known as bromodomains.an important means of modulating any process that involves accessing the DNA. Learn vocabulary, terms, and more with flashcards, games, and other study tools. Diagrams. Start studying Chapter 8: Chromosomes, chromatin and the nucleosome.
Chromatin is the genes uncoiled in the G0 phase and chromosomes are genes coiled and compacted together before cytokinesis and after Gap 2.
The cell's chromatin condenses into chromosomes during prophase. How is DNA shaped?
The major purpose of chromatin is to pack the double-stranded DNA into the cell nucleus with the aid of histone proteins. Help Center.
Like a twisted ladder.
histone protein isa linear and highly compacted and organised DNA molecules with associated proteins which encodes genetic informationthe region of a chromosome which links sister chromatids. Contains one double-stranded DNA molecule.series of events that lead to the replication and segregation of chromosomal DNA during cell division.how many sets of identical chromosomes a cell containsthe copy of each chromosome inherited from the mother is homologous to the copy inherited from the father ( it contains the same genes and gene order but different versions of each gene). This could be because heterochromatin is more condensed or because the nuclease reacts different with DNA bound by specific heterochromatin proteins.a location in the chromosome at which DNA replication beginsremoves the positive charge from lysine side chains and thereby alters interactions with the negatively charged DNA. The two look different:
(gap phase I), cell growth occurs until cells attain a minimum size that is required to progress to the next phase.
