Circles and Ovals DO have lines of symmetry: a circle has an infinite number of them (each is a diameter of the circle) and an oval (ellipse) has two (one along the major axis, one along the minor axis).
Shapes which have no lines of symmetry are irregular ones, eg scalene triangles, along with most parallelograms (ie parallelograms which are not rhombuses) and non-isosceles trapezia.
Some irregular shapes can have lines of symmetry, eg irregular octagons can have 1, 2 or 4 lines of symmetry as well as no lines of symmetry, unlike a regular octagon which [always] has 8 lines of symmetry.

What shapes don't have lines of symmetry?
Ovals; circles; any circular shape with no edges or corners
Do all shapes have lines of symmetry?
not all shapes have lines of symmetry. one example is a triangle.
Shapes with more than 4 lines of symmetry?
A regular hexagon has more than 4 lines of symmetry. Even number sided polygons that are regular and have more than 4 sides have more than 4 lines of symmetry. Circles have more than four lines of symmetry. Squares also have 4 lines of symmetry.

Does all shapes have line of symmetry?
No. Asymmetric shapes do not have any lines (or planes) of symmetry.
How many line of symmetry do perfect circles have?
They have infinite lines of symmetry.

What shapes are in DNA?
Circles and curved lines.
What is the symmetry of sphere?
Three dimensional shapes, generally, don't have lines of symmetry, but a circle has an infinite number is symmetry lines. 3D shapes also don't have rotational symmetry either, but a circle has an infinite number of that as well.
