Answer:

Because each chromosome was duplicated during S phase, it now consists of two identical copies called sister chromatids that are attached at a common center point called the centromere.

What could you make or do to make sure your bean plants stay upright and don’t fall down?
nlexa [21]

Answer:

I got this off of g o o g l e

Explanation:

I put pairs of small fence posts (one on each side) down the row. I then tied twine to the fence post and ran it on either side of the plants. This keeps them from falling over to the side. If you plant thick enough they won't fall to the front or back.

How does cloning work and work are the basics​
Musya8 [376]

Answer:

How cloning works: In reproductive cloning, researchers remove a mature somatic cell, such as a skin cell, from an animal that they wish to copy. They then transfer the DNA of the donor animal's somatic cell into an egg cell, or oocyte, that has had its own DNA-containing nucleus removed. ... This young animal is referred to as a clone.  

Basics of cloning:

Isolation of target DNA fragments (often referred to as inserts)

Ligation of inserts into an appropriate cloning vector, creating recombinant molecules (e.g., plasmids)

Transformation of recombinant plasmids into bacteria or other suitable host for propagation.

Screening/selection of hosts containing the intended recombinant plasmid .

Only the proteins that the bacteria Escherichia coli (E. coli) needs are synthesized at any given time. For example, when lactos
nataly862011 [7]

The correct answer is A. Lac repressor.

Lac repressor prevents lac gene which are found in the DNA of Escherichia Coli from being expressed for many times.

Lac repressor is termed as DNA which binds proteins. It allows the expression of genes from coding which are made for proteins to be involved in metabolism of lactose which is in bacteria.

When there is no lactose which is available in the cell, then the genes are being repressed. Lactose are being converted to allolactose if they are available.

In pea plant the trait of yellow seeds (YY) is dominant over green seed (yy). Explain the inheritance pattern of F1 ad F2 genera
storchak [24]

Answer:

F1= All Yy

F1= All yellow

F2=  1/4 YY: 1/2 Yy: 1/4 yy

F2= 3/4 yellow: 1/4 green

Explanation:

The allele for the yellow-colored seeds (Y) is dominant over the allele that imparts green phenotype (y). A cross between two pure breeding yellow seeded and green seeded plants would obtain all yellow seeded plants in the F1 generation. Self-pollination of F1 progeny would obtain F2 generation in following phenotype and genotype ratio:

Phenotype ratio= 3/4 yellow: 1/4 green

Genotype ratio= 1/4 YY: 1/2 Yy: 1/4 yy
