As DNA replication begins the DNA molecule is broken apart into two ________ strands.
Serjik [45]
As DNA replication begins the DNA molecule is broken apart into two complementary strands. DNA replication is the process by which DNA makes a copy of itself during cell division. The process occurs in all living and is the basis for biological inheritance. The process starts with the separation of DNA strands in the double helix. Then replication for is formed followed by the binding of bases to each strand. Then the last step is termination of the Replication process

Word bank: (Thermosphere) (Aurora boreal is) ( Large-scale air turbulence and mixing at this layer) ( Stratosphere) (The coldest
Lyrx [107]
  • Thermosphere - Fourth layer of Earth's atmosphere.
  • Aurora Borealis - Ionosphere layer of thermosphere.
  • Large-scale air turbulence and mixing at this layer - Troposphere
  • Stratosphere - Second lowest layer of Earth's atmosphere. No Air turbulence so airplanes fly in this layer.
  • The coldest temperatures in the atmosphere occur at the junction- of Stratosphere and mesosphere
  • Maximum ozone - Ozone layer in Stratosphere

Explanation:

Atmosphere is formed by mixing of gases. The layers of atmosphere is given below.

1. Troposphere -

  • The first layer of the atmosphere.
  • Weather occurs in this layer.

2.Stratosphere -

  • The second layer of Earth's atmosphere.
  • Contains Ozone layer.

3. Mesosphere -

  • The third layer above the stratosphere.
  • Coldest layer.

4. Thermosphere -

  • The fourth layer of the atmosphere.
  • Warmest layer.
  • Ionosphere - lowest level of thermosphere above mesosphere.
  • Aurora Borealis, Northern and Southern lights are seen in this layer.
  • Exosphere - outermost layer of thermosphere.
  • Satellites are in this layer.
  • Outer space with no gravity.

Forward primer: 5'-AGTCTACTCGTAACCGGTTACC-3' Reverse primer: 5'-TAAGGCATCATGGTAACCGGTT-3' The two primers above have the melting
CaHeK987 [17]

Answer:

Short answer is primers are partially complementary.

Explanation:

Forward primer: 5'-AGTCTACTCGTAACCGGTTACC-3'

Reverse primer: 5'-TAAGGCATCATGGTAACCGGTT-3'

When we write reverse primer 5' to 3' we can easily see that

3'-TTGGCCAATGG---5' is complementary to the forward primers'

5'---AACCGGTTACC-3' sequence. So instead of binding to the template DNA these primers might bind each other resulting with reduction of efficiency of DNA amplification.
