A DNA sequence is shown. AAT - CCG - GTG Which sequence best shows the result of a substitution mutation in the DNA?

1 answer:

6 0

Mutations are sudden spontaneous random changes that occur in the genetic make up of an organisms. A substitution mutation is a type of mutation that exchanges one base for another, for example a change in a single base such as switching an A to a G). Substitution could cause a change of codon to one that encodes a different amino acid and cause a small change in the protein produced. In the above sequence AAT-CCG-GTG in substitution of a single base

Can anyone help with one or two of these questions? ill give brainliest

Marianna [84]

Answer:

1. 1.00(1/2)^151/30.2= 31.3 g

2. 24g-->1.4 g = 4 half-lives, so 4*5730= 22920 years

3. 64g-->2.0g = 5 half-lives, so 12.5/5= 2.5 hours

What determinant of mean arterial pressure would be directly affected by lasix, and would this typically raise or lower mr. unde

Marysya12 [62]

<span>By definition, the two determinants of mean arterial pressure are cardiac output and total peripheral resistance. It has been shown that Lasix decreases cardiac output and total peripheral resistance. Diuretics increase urine production, so it will lower mean arterial pressure.</span>

Ryan wants to see if storing his batteries in the refrigerator will make them last longer. He goes to Target and buys four batte

bulgar [2K]

<span>The battery which Ryan kept in fridge, assuming it was well protected from any moisture or water, it would tend to play the CD longer than the one stored in a desk drawer. This is because storing batteries in a cool dry location while protected from any moisture or water, can help to prolong shelf life. This is due to the fact that low temperatures tends to slow down the electric current flow within the electrolyte fluid inside the battery, hence, the rate of power dissipation is reduced thus slowing down of the power drain from battery by the electric current flow . Thus, the battery stored in the fridge tends to have lost less power, if any, compared to the one stored in a desk drawer.</span>

Each anticodon carries _____________ amino acid.

AfilCa [17]

Answer:

Do you use the codon or Anticodon to find the amino acid?

String of amino acids make up protein's primary structure. anticodon – a sequence of three nucleotides on a tRNA molecule that bond to a complementary sequence on an mRNA molecule. The anticodon sequence determines the amino acid that the tRNA carries.
