Answer:

Extremophiles are a relatively small group of bacteria that thrive in extreme conditions. An example is Picrophilus torridus

Pathogenic bacteria are the bacteria which cause diseases.

Eubacteria are classified into Chlamydias, Cyanobacteria,Gram-positive bacteria, Proteobacteria, and Spirochetes.

The spherical shape Bacteria is called cocci , the rod shape bacteria is called bacilli and the spiral shape bacteria is called spirilla

Gel analysis of fragments in step 6 shows that even though the undigested DNA and DNA digested with HindIII are both 1000 bp, th
Soloha48 [4]

Answer:

Size of the band varied

Explanation:

In the given question, the options are not provided but based on the information provided in the question, it can be predicted.

When the DNA was digested by the HindIII, then the length of the digest came about 1000 bp and the undigested DNA was also found 1000 bp.

When both the bands were analysed by Gel electrophoresis then the bands do not run to the same distance therefore this shows that the size of both the bands was not equal and their size varied.

Thus, the size of the band varied is correct.

A line graph has a vertical axis labeled "Average plant mass (g)^ * and a horizontal axis labeled "Herbicide (g/plant)." What in
SSSSS [86.1K]

Answer:

The correct option is D. The average mass of plants exposed to 3 g of herbicide was 10g.

Explanation:

As the vertical axis is labelled as average plant mass, it will make the y- coordinate.

As the horizontal axis is labelled as Herbicide (g/plant), it will make the x-axis.

The coordinates for the given value are (3,10). 3 will be the value of the x- coordinate. Hence, it will show the average mass of the plant at the plotted point which will be 3 g.

10 will show the value of the y- coordinate which will be the amount of herbicide given to the plant.

Hence, Dis the correct option.

Suppose that a scientist deletes the AAUAAA consensus sequence, the poly(A) tail, or the 5' cap from pre‑mRNAs in an mRNA. She t
Andrej [43]

Answer:

<h2>AAUAA deletion- (B ) </h2><h2> </h2><h2>Poly(A) tail deletion- (C) </h2><h2> </h2><h2>5' cap deletion-  (A) </h2>

Explanation:

(A) introns are not removed from the pre-mRNA due to 5' deletion;

(B) the pre-mRNA is not cleaved at the cleavage site due to AAUAA deletion

(C) the mRNA is not transported to the cytoplasm due to poly A tail deletion;

AAUAA deletion:  if we delete the AAUAA  sequence then there is the change of sequence of pre- mRNA that the pre-mRNA is not cleaved at the cleavage site .

Poly(A) tail deletion: Poly(A) tail is the long tail of Adenine in the 3' end of mRNA, after the deletion of Poly(A) tail, it affects the transport of mRNA from the nucleus to the cytoplasm and  the mRNA is not transported to the cytoplasm if tail is deleted.

5' cap deletion; the effect of 5' cap deletion is that introns are not removed from the pre-mRNA. The process of intron removing and exon joining is called RNA splicing.
