Answer:

What are the differents parts of a bacteriophage?

The tailed phages have three major components: a capsid where the genome is packed, a tail that serves as a pipe during infection to secure transfer of genome into host cell and a special adhesive system (adsorption apparatus) at the very end of the tail that will recognise the host cell and penetrate its wall.

Where is the DNA stored in this virus?

Where is DNA stored in viruses?

The genome of most DNA-containing viruses that infect eukaryotic cells is transported (with some associated proteins) into the cell nucleus, where the cellular DNA is, of course, also found.

Elanso [62]

<span>Oxygen travels to insect tissues through tiny openings in the body walls called spiracles, and then through tiny blind-ended, air-filled tubes called tracheae. Therefore, insects obtain oxygen through the spracles, which are small abdominal holes that lead into traecheal tubes called tracheae that branch into smaller tubes called tracheoles. From there, oxygen diffuses into body cells.</span>

Number the following steps in the correct order and tell which stage it occurs in:

Sedaia [141]

Answer:

The correct answer is given below:

Explanation:

1. A cleavage furrow or cell plate forms, separating the nuclei - Cytokinesis. During cell division, after division of nucleus, cytoplasm divides by furrow in an animal cells and by cell plate formation in the plant cells.

2. Chromosomes line up at the equator and chromatids are attached to spindle fibres—Metaphase. During metaphase all the chromosomes get arranged on the equatorial plane or the central plane

3. Nuclear membrane and nucleolus reappear- Telophase. The nuclear membrane starts to form around each of the daughter chromosomes and nucleolus also reappears in the daughter nuclei.

4. Genetic material replicates and is joined at the centromere- S-phase of the interphase. Duplication or copying of the DNA occurs in this phase

5. Centromeres divide and single-stranded chromosomes move to the poles- Anaphase. During anaphase, the sister chromatids of each chromosome gets separated and move to the opposite poles.

Answer:

see below

Explanation:

amplification: MUTATION = a type of mutation

independent assortment: MENDELIAN = how different

genes independently separate from one another

when reproductive cells develop

nondisjunction: MUTATION = a type of chromosomal

mutation

translocation: MUTATION = another type of chromosomal

mutation

codominance: MENDELIAN = a relationship between two

genes where neither allele is recessive and both

are expressed

insertion: MUTATION = a type of mutation

radiation: MUTATION = causes mutations

virus: MUTATION = causes mutations as the virus

replicates

deletion: MUTATION = a type of mutation

law of dominance: MENDELIAN = one of Mendel's laws

of inheritance

sex linked traits: MENDELIAN = linkage is an exception

to Mendel's law of independent assortment

incomplete dominance: MENDELIAN = when none of the

factors of a gene is dominant and there is a blend,

such as a red flower crossed with a white flower

turns out pink

law of segregation: MENDELIAN = one of Mendel's laws

of inheritance

substitution: MUTATION = a type of mutation
