What does each phase of mitosis look like

Sphinxa [80]

Interphase: You could not distinguish any parts of the cell.
Prophase: You could clearly see the chromosomes throughout the cell.
Metaphase: The chromosomes where lines up in the middle of the cell.
Anaphase: You could see the chromosomes were separated to ether side of the cell.
Telophase: The entire cell was separated to each side but was not split into its own cell.
Cytokinesis: In this step the cell had totally separated and there was now two separate daughter cells.

atch the statement to the following options.A. One of a pair of chromosomes with similar genetic information and from different

Goryan [66]

Answer:

A. Homologue.

B. Chiasma.

C. Synaptonemal.

D. Synaptonemal.

E. Synapsis.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

Synaptonemal complex can be defined as a network of proteins that is responsible for holding homologous chromosomes (homologues) together.

Generally, a synaptonemal complex (protein lattice) is formed between homologous chromosomes during mitosis and meiosis. Also, synaptonemal complex is important for the formation of the four sister chromatids referred to as tetrads.

Furthermore, the synaptonemal complex (protein lattice) has a tripartite structure which comprises of the following components;

I. SC protein-1 (SYCP1).

II. SC protein-2 (SYCP2).

III. SC protein-3 (SYCP3).

In conclusion, the synaptonemal complex plays a significant role in synapsis, recombination and chromosome pairing.

Matching the various terminologies in genetics with their description, we have;

A. Homologue: one of a pair of chromosomes with similar genetic information and from different sources like the sperm and egg.

B. Chiasma: several X-shaped structures may be visible under the microscope and indicate where crossing over has occurred.

C. Synaptonemal: a lattice of protein holds two replicated chromosomes in precise register with one another.

D. Synaptonemal: four chromatids are held together by a zipper-like structure.

E. Synapsis: a process in which pairs of homologous complex chromosomes line up side by side.

If you buy 3kg of pasta for dinner party how many pounds of pasta are you actually preparing for dinner?

GalinKa [24]

Given :

Mass of pasta buy for dinner party , M = 3 kg .

To Find :

How many pounds of pasta are you actually preparing for dinner .

Solution :

We have to convert 3 kg to pounds .

We know , 1 kg is equal to 2.2 pounds .

So , mass of 3 kg in pounds is :

$M=2.2\times 3\ pounds\\\\M=6.6\ pounds$

Therefore , 6.6 pounds of pasta is preparing for dinner .

Hence , this is the required solution .

Which of the following is true about operons? O Operons afford the organism the opportunity to simultaneously regulate transcrip

mars1129 [50]

Answer:

Operons afford the organism the opportunity to simultaneously regulate transcription of multiple genes, whose products are active in the same process.

Explanation:

Operon is the group of related genes and the operator and promoter sequences that regulate their expression. All the genes in an operon are expressed together and are under the regulation of the same promoter and operator sequences.

Operons consist of the genes that are involved in related metabolic pathways. For example, the genes that code for the enzymes of lactose catabolism are expressed together as lac operon. It allows simultaneous expression of the genes of lactose catabolism only when lactose is present in the medium. Similarly, these genes are inhibited simultaneously in absence of lactose by binding of repressor protein to the operator sequence.
