A segment of dna has 320 nitrogen bases. if 40 of them are cytosine, how many are thymine
NISA [10]
Correct answer - 120 for Thymine.

Why? - 320 Nitrogen bases.
Cytosine = 40, Cytosine = Guanine.
Therefore Guanine = 40.
320 - 80(Cytosine and Guanine)
240.
Adenine and Thymine = ?
Adenine = x and Thymine = x.
2x = 240.
X = 240/2
X = 120.
Adenine 120, Thymine = 120, Cytosine = 40 and Guanine = 40.

What is the job of tRNA
exis [7]

Answer:

To make our mRNA

Explanation:

I think it is this one, but I am not sure, sorry if it is wrong. :(  

But I do know this, I think it might help you:

A transfer RNA (tRNA) is a special kind of RNA molecule. Its job is to match an mRNA codon with the amino acid it codes for. You can think of it as a kind of molecular "bridge" between the two. Each tRNA contains a set of three nucleotides called an anticodon.

Treating a sick mango for fungal diseases involves using a fungicide. All susceptible parts of the tree should be thoroughly coated with the fungicide before infection occurs. If applied when the tree is already infected, the fungicide will have no effect. Fungicide sprays need to be reapplied on new growth.

One possible result of chromosomal breakage is for a fragment to join a nonhomologous chromosome. What is this type of chromosom
san4es73 [151]

Answer:

Translocation

Explanation:

Changes in chromosome include deletions, duplications, inversions, and translocations.

  • Deletion occurs when an end of a chromosome breaks off.
  • Duplication is the presence of a chromosome segment more than once in the same chromosome.
  • Translocation is when a fragment of chromosomal breakage join a nonhomologous chromosome.
  • Reciprocal translocation is a chromosome abnormality caused by exchange of parts between non-homologous chromosomes.
  • Robertsonian translocation occurs when two non-homologous chromosomes get attached, meaning that given two healthy pairs of chromosomes, one of each pair "sticks" together.

Waters in the coastal ocean tend to be more productive than waters of similar depth in the open ocean. What is the main reason f
Jet001 [13]

Answer:

The coastal ocean seems to be more productive than the waters of the similar height in the open ocean due to ample availability of water, sunlight, and nutrients. The coastal ocean has more nutrients due to the process of upwelling, that is, movement of water offshore by the currents.

Also, water situated on the continental shelves is comparatively shallower and thus it is turbulent. This mixing or turbulence keeps settling the nutrients stirred up and accessible, and eventually, ample of nutrients erode off the continents themselves and so water nearby to the shore seems to be greater in nutrients.  

On the other hand, in the surface water away from the coastlines, usually, there is a lot of sunlight but no availability of adequate nutrients. Therefore, the majority of the ocean surface is not much productive.
