Answer:

The restriction endonucleases in bacteria (b) they provide a defense mechanism against infection by viruses

Explanation:

The restriction endonucleases is a protein that is produced by the bacterias that interacts with the DNA of them and gives protection to the bacterial cell by defending against viruses.

Is important to remember that viruses go into different organisms just with a copy of DNA that wants to replicate inside of them creating more and more copies until it breaks the hosting cell and this is how the infection spreads. This protein restricts (that's the reason of its name) or stops the replication stage of the virus DNA by cutting it into many pieces stopping in this way the spread of the infection and the death of the bacteria.

lara31 [8.8K]

Answer: AUG GU UGG AAU

Explanation: Since it's a point mutation which only effects single nucleotide; so in CGA codon, the second codon, deletion mutation has been occured while mRna strand is going to be synthesized, this has shortened the length of the resulting protein developed from these codons.

Since RNA contains uracil instead of thymine, so in place of thymine (T), uracil has been placed.

Given the parents AABBCc × AabbCc, assume simple dominance for each trait and independent assortment. What proportion of the pro

Anit [1.1K]

Answer:

3/4

Explanation:

If we assume simple dominance and independent assortment for each trait, we can use Mendel's Law of Segregation to predict the phenotypic proportions in the offspring of the parental cross AABBCc x AabbCc.

AA x Aa

F1 genotypes: 1/2 AA, 1/2 Aa
F1 phenotypes: all A

BB x bb

F1 genotypes: 1 Bb
F1 phenotypes: all B

Cc x Cc

F1 genotypes: 1/4 CC, 2/4 Cc, 1/4 cc
F1 phenotypes: 3/4 C, 1/4 cc

We want to know the proportion of progeny with all dominant phenotype (A_B_C_). Since the genes are independent, we can multiply the probabilities of each gene to obtain the overall probability of having a ABC progeny:
